2014 Engine Rules Confirmed

The World Motor Sport Council voted on the engine regulations for 2014 on Thursday and the proposed changes have now been ratified and accepted. This means that the proposed rules are now accepted by everybody who has a choice about them and so are highly likely to go ahead. But what are the new changes all about?

The Engine

The new engine configuration will be a 1.6 litre V6 using a single turbocharger and energy recovery systems. This layout is a compromise on the original suggestion of an inline 4 to help keep Formula 1 more appealing to sports car manufacturers (read Ferrari mostly!) It also allows the engine to be used as a stressed part of the chassis which helps the manufacturers to build a better car around it.

Direct fuel injection will be used at up to 500bar along with a fuel flow control system to help limit maximum power. The engine speed has been raised to 15000rpm, apparently to allow engineers more flexibility in power and energy management. Because the fuel flow has remained the same this should lead to even more efficient engines than the previous proposals.

There will also be two energy recovery systems. First, a beefed up KERS with twice the current energy storage. It has not been made clear exactly how this will affect its operation during a race yet. It could be the same time allowed to use it with double the power boost, double the time allowed at current power levels or some variation in between. Second will be an exhaust energy recovery system linked to the turbocharger. Turbos are normally run by exhaust gases anyway so exactly what this will turn out to be is still a little unclear.

The Effects

One of the complaints about the new regulations is that the noise will not be the same. Formula 1 cars are incredibly noisy things and it is thought that this is one of the big selling points of the championship. Personally I'm not so sure. No doubt the noise is one of the things that you always remember about seeing a Formula 1 car in person, but its not as if there is suddenly a need to use silencers. It will sound different of course, but you can be sure that it will still be very loud indeed.

Formula 1 has used inline 4 cylinder engines in the original turbo era during the 1980's. Although there was a lot of talk about how fair the turbos were compared to normally aspirated engines, I don't seem to recall any talk at all about the noise.

Efficiency

The efficiency of the engines has been talked about a lot and this is something where I think the FIA are moving in the right direction. The rev limit on the engines has been raised, but in order to take advantage of those extra power cycles you need to fill the engine with fuel. The flow rate has not been raised so that means you absolutely must have a more efficient engine. The only ways around this simple equation is to use more of the wasted power and this is where the energy recovery comes into play. If we assume that the exhaust system will be used for more than just spinning the turbo, this is where the engineers get to start being clever and think up new ways to increase the amount of forward motion from a set amount of fuel. It seems that, as long as a little freedom is given in this area, we might actually see some interesting technology start to appear from F1 again.

I have seen it mentioned that Formula 1 would save more fuel by rearranging the logistics of the races than by reducing the fuel used in the race cars. In purely mathematical terms that is absolutely true, but it does miss the point a little. Fuel prices are not going to go down at any point and it makes no sense for F1 to continue along what is essentially a dead end in car development. The current engines are way beyond what can be responsibly put into a road car already. Changing the rules will bring them back into the area where they have some connection to the cars ordinary people use. A pretty tenuous connection yes, but it is there. Efficiency is the new feature that all cars must have, in much the same way as safety was before it. For Formula 1 to be lagging behind won't be good for its image, and for the manufacturers that image, and the sales it generates, is everything.

Valencia, the Low Point of an Exciting Season

The European Grand Prix at Valencia was definitely more exciting than the last three times it has been run. But sadly in a year of stunning races, this was definitely the most dull. Can anything save this race from being a bit rubbish or is it just a lost case? And how can anyone persuade Bernie to get rid of it? It showed promise early on though...

Qualifying

It was very hot for the start of qualifying and continued to get hotter throughout the session, combined with the slippery track here there was a chance of some errors creeping in. Predictably, Vettel set the early pace but Jenson found a little more speed shortly after as the track improved. Ferrari, McLaren, Red Bull were all very close as the session continued and then Nico Rosberg jumped up to fourth as the last runs began to show that Mercedes are still involved as well. The shuffling started to push Webber and Massa down towards the drop zone but they both saved themselves at the last with Massa taking fastest lap by 0.6 seconds.

In Q2 most of the drivers had their fast laps done nice and early which was lucky for them. Pastor Maldonaldo broke down in the middle of the track and bought out the red flags for a few minutes as a crane had to rescue him. The fast guys didn't bother to go out again after that. Paul di Resta was trying hard at the end but his lap was too scruffy to be quick and he lost out on a place in Q3. His team mate, Adrian Sutil, did make it in though, which made for a good result for Force India.

With 5 minutes of Q3 remaining  the top six was Vettel, Hamilton, Alonso, Webber, Button and Massa. The top 4 all decided to do another run at the end, Webber set off first and Vettel was the last. By the end of his flying lap though, Vettel hadn't improved and jumped into the pits to save his tyres. Webber managed to get a faster time but only good enough for second. Button somehow ended up in 6th place as the cars all came home and another slightly disappointing qualifying session ended.

Race

The cars lined up on the grid on an even hotter day than Saturday which was making the teams nervous about how long the tyres might last.

As the lights went out both Ferraris got good starts with Massa getting the best of all. Hamilton bogged down a little and both of the red cars were past him by the first corner. Alonso made the best of the second turn though by running around the outside and putting himself into third on the way out of the corner. Massa tried to continue his run off the grid but had to back out of it and settle into 4th. In the confusion Button ended up knocked down to 7th as Rosberg squeezed past into 6th behind Hamilton.

By lap 2 Sebastien Vettel had opened up a 1.3 second gap on Webber and didn't look as though he would have any trouble keeping it. As the DRS became active it was Button who was in the best position to take advantage to it. Sadly it didn't seem to be working to well for him, he was getting closer to Rosberg with the flap activated but not close enough to get past. Rosberg started to get a bit ragged as the pressure built, but it was on the way into turn 2 where Jenson finally just forgot to brake for a few metres and dived through on the inside.

Fernando Alonso was closing on Mark Webber up to lap 6 but didn't seem to be making enough headway to get through. In trying to hard he ran very wide on turn 20, right across the astroturf section and giving Webber a little more breathing space. Vettel was widening the gap as Fernando started again on catching Webber.

Lap 10 saw Massa overshoot turn 17 but Hamilton wasn't close enough to take advantage. The pit stops began on lap 12 with Heidfeld and Kobayashi being the first to blink. Hamilton was in the next lap and it was clear that nobody would be able to make the tyres last much longer as Vettel was starting to get some oversteer moments. Webber was the first of the Red Bulls to stop followed by Vettel on lap 15 with Alonso right behind him and Massa the lap after.

Michael Schumacher came out of the pits and tried to take the inside of turn 2 as Petrov was coming past. Vitaly thought the corner was his and turned in, loosening the front wing of the Mercedes. It proceeded to get more broken and despite managing to get past a Force India it ended up trapped under the side of the car by the tie he made it back to the pit. After an investigation by the stewards no action was taken.

The top three drivers were still less than 4 seconds apart by this stage. Webber found himself stuck behind some traffic at this stage which let Alonso get a little closer and the Spanish crowd were starting to get up on their feet every time he went by. He finally found a space and out-braked the Australian on the way into turn 12 and started to open out a gap.

By lap 22 Button was being told on the radio that the cars in front would start "degging" soon, indicating that their tyres would be degrading fast. A couple of laps later and Hamilton was informed that he was on the same pace as the cars behind. Normally this would get Lewis asking what about the cars in front, but not this time. The McLaren cars didn't seem to be showing the same pace they have had in the last few races, and it seemed as though this might be as far up the field as they could make it.

Later on during lap 27, with a fresh set of tyres, Lewis still found enough to put in fastest lap of the race up to that point. His engineer was on the radio asking him, "please manage your pace," or in other words, "don't wear your tyres out too quickly!" Webber made his second stop on lap 29 with Alonso coming in one lap later but he came back onto the track behind Webber.

By lap 30 Lewis was getting warnings from the pit again, this time his rear tyre temperatures were too high. To which he replied, "I can't go any slower." That's the sort of attitude we like to see! As Button pitted for his second time, Webber was catching Massa fast and dived past him as the Brazillian dealt with some traffic on the way into the pits.

Button was on the radio on lap 33, being told that his KERS was not working. This prompted the McLaren engineers to go and get their rubber gloves out. Hamilton was again not doing the right thing and on lap 40 he got another message from the team to up his pace. The reply this time, "I'm going as fast as I can go!"

Now the track started to make its mark on the race properly as no real progress was made by anyone for a long time. There were some good scraps in the midfield, but compared to the races so far this year it was quiet and almost processional. Despite the top three still being within 12 seconds on lap 50 nothing really seemed to be heating up and the top 6 finished as they had been for more than 10 laps.

Vettel seemed to be particularly pleased with this victory for no reason that anyone could fathom out. It just looked like another of his pole to flag victories, despite his romantic claims that its him against the car and the track. Sadly for us it seems to be the track that is the problem. As Tiff Needell tweeted afterwards, "Even Pirelli's best efforts and the wing flappy thing can't turn a truly boring circuit into a racing track."

The final result ended as Vettel from Alonso with Mark Webber taking the final podium position. Hamilton stayed in fourth with Massa, Button and Heidfeld behind that. Jaime Alguersuari got himself a good eighth place to boost his season, despite this being one of only three Formula 1 races ever where everyone who started also finished. And one of those was the infamous Indianapolis race where only 6 cars started.

Valencia is just a track which doesn't seem to inspire any racing and its hard to say why. It's a great location, not as narrow as a street circuit but still with walls that should make mistakes count. Long straights, tight twisty sections. Everything it should need is there, but just put together in a way that makes it dull.

Still, next time out is the British Grand Prix at Silverstone and that is a track that often produces a good race. It can be helped out by the Great British weather of course, but this year there are also major changes to the circuit. Specially designed to create mistakes and introduce more passing. With the added bonus of the Pirelli tyres and DRS this should help make it the sort of race that has been keeping us interested for the first part of the season. Come on the Brits!

Rule Changes, Rule Changes and Changes to the Rules

The FIA have finally decided to implement the long discussed ban on blown diffusers from the British Grand Prix onwards. But of course, that on its own would be too easy, so an there is an extra change to the rules (effective immediately) which bans any change in engine mapping between qualifying and the race. Just to add a little more entertainment it has also been decided to postpone the major engine regulation changes to make Formula 1 greener, from 2013 to 2014.

The ban on hot blown diffusers has been talked about for a little while now and the FIA have finally got round to making a ruling on it. From Silverstone the teams must change their engine mapping so that when the throttle is closed no more than 10% of the maximum fuel flow is allowed into the engine. Some of the teams have been using a system where the fuel flow is kept high but the ignition is retarded so much that the fuel burns in the exhaust. This allows hot gas to exit the exhaust and create more downforce under the car. Now that this is to be restricted, we are left to wonder which cars will be most affected by the change. Its widely believed that Red Bull will see the biggest hit but nothing is certain until the British Grand Prix.

The teams have also been issued another ruling which will take effect this coming weekend in Valencia. Once qualifying is finished there are to be no changes to the engine mapping until the race is underway. Previously it was not regarded as a breach of Parc Fermé rules to plug in a laptop and make alterations to the ECU settings. This allowed the cars to use a far more aggressive mapping during qualifying, and then change the setting down for the race in order to stop the floor and exhaust from overheating. Again Red Bull are thought to be the biggest loser in this change. Their cars never quite seem to have the domination in the race that they show on Saturday.

It should be interesting to see if this has any noticeable effect during the European Grand Prix. Theoretically it is possible to change the engine mapping during a pit stop. But due to the time required, no-one seems to believe that it will happen, which means that the other cars may be a little closer to Vettel than normal. Some are unhappy that these changes weren't left until the end of the season but it does seem to slow down another (presumably) expensive line of research and may even help to close up the championship race. Which is never going to be a bad thing!

Finally the major engine changes that were to be introduced in 2013. It was believed that the FIA had secured agreement for a change to 4 cylinder turbo-charged engines to be introduced in 2013 but now, after a meeting with all the teams a new agreement has been reached. And this time that means that everyone agrees. This will see Formula 1 moving to 1.6 litre V6 turbo-charged engines instead of the current 3.5 litre V8. There will also be a reduction in fuel flow along with a rev limit reduction from 18,000 to 12,000 rpm which should see fuel usage drop by up to 35%. These changes should see the current power output of around 750bhp stay roughly the same. KERS will also be beefed up to twice its current output.

These changes are intended to make the sport greener, but how green can a sport like motor racing really be? These are cars that have no purpose other than moving one man around and around in a circle as fast as possible. Not going anywhere as quick as you can is, by its very nature, a waste of fuel and energy. It is hoped however that the turbo chargers and energy recovery systems may boost the use of the same  technologies on road cars, which can only be a good thing.

In my opinion, the only real way to make F1 greener would be to limit the total amount of fuel used per race and drop that amount season by season. The teams would be allowed to use whatever other sources of energy they can (KERS, solar power, Mr. Fusion etc.) to make up the shortfall and increase the efficiency. Then we might see a technical battle worth watching and it might have a greater impact on the rest of the road-going world.

Canadian Grand Prix is a Four Hour Epic

This year's Canadian Grand Prix was in every way an epic race. Stopped, restarted, rain, sun, safety cars and accidents, this race had it all. And even a fairy tale ending.

Free Practice 3

Early on Saturday third practice saw Vettel fastest again while Pedro de la Rosa took the back wheel off his borrowed Force India. McLaren again couldn't get close to the Ferrari's and Vettel. Mark Webber however didn't get any running at all as his car was pulled apart to try and repair the KERS. Once again the KERS system costs Red Bull. Apparently their System only puts out 66% of the maximum allowed power. They claim that the lower weight and smaller size allow them to gain back performance in other ways. So far the balance seems to be right but if the KERS doesn't work at all, as seems to be happening so far, they are definitely losing out.

Qualifying

As qualifying started Martin Whitmarsh claimed that McLaren are setting the car up for wet weather due to the weather forecast showing a 60% chance of rain during the race. A lot of cars got out nice and early for qualifying 1. It looked as though there could be a chance of rain at any minute and there was also the chance of an accident stopping the session that forced them out for a banker. The drivers were opting for up to 3 flying laps as well, the soft tyres seemed to get faster as the temperature built up.

The top 6 was established pretty early on in the session with Fernando Alonso setting the fastest time. Paul Di Resta put in a fantastic lap to put himself in 8th place by the end of the session. Pedro De La Rosa provided some entertainment by running a little wide and skimming the wall with both wheels causing a shower of sparks. Somehow he avoided any damage and complete his lap but his speed was nothing to write home about.

Q2 saw some pretty close times, with seven minutes remaining the seven drivers were all within 3 tenths of a second. Kobayashi once again proved himself an absolute hero as he tried to get the best out of his car. The rear end got a little loose in the last chicane. He kept his toe down and drifted it round while looking like he was steering straight at champions wall. He survived it but it was clearly not the fastest way to do it. Paul Di Resta was also trying hard but couldn't do any better than 11th this time out. Massa was on top by the end of the session but only by a very small margin.

Q3 was almost settled by halfway through. Most of the cars went out for a second run but failed to improve except for Alonso who jumped just past Massa to put himself second on the grid. The final grid order was Vettel on pole, Alonso second and Massa third. Hamilton ended up in fourth followed by Webber while Button could only climb up to 7th. It turned out that Mark Webber wasn't able to use the Red Bull KERS at any time during qualifying which shows exactly how much damage it can do to the performance.

Race

The track was wet as the start of the race approached, but it wasn't actually raining which raised hopes that the race would be able to start normally. Those hopes were to be dashed though, the safety car was at the front of the grid as the cars pulled away. Jaimie Alguesuari seemed to have made a great decision at this point. He had elected to start from the pit lane to allow the team to make some changes to the car and now he didn't  even have to catch up with the end of the field.

The safety car came in on lap 5 and the teams were put into a race situation on full wet Pirelli tyres for the first time. Vettel tried to start early to get a jump on Alonso but the Spaniard was right with him and trying hard to challenge on the start finish straight. As the rest of the cars followed through Hamilton found himself outbraking Mark Webber. It seemed as though he bounced of the kerb a little and knocked the Australian into a 180. The stewards almost immediately sent out a message that they were investigating the incident, no surprises there!

It appeared that Vettel was pulling out a four second lead, but replays showed that he had a short cut across the grass to help him with at least some of that. As Hamilton tried to regain the positions he had lost after his contact with Webber he came up behind Button. On the way out of the last chicane he got a much better run and dived towards the pit wall to try and overtake. Either Jenson hadn't seen or just wasn't expecting Lewis to be that fast as he moved over and the cars hit each other and Lewis hit the pit wall. Hamilton's car looked as though it was losing a wheel but he tried to make it back to the pits. He had to give that up by turn 5 though and parked it on the track, which bought the safety car back out again.

Jenson dived straight into the pits for a check up and a set of intermediate tyres. The car seemed to be ok and he rejoined the race a long way back and the only one on those tyres. A new message arrived from the stewards at this point. The investigation against Lewis for contact with Webber was dropped (yay!) and a new one was started. This time it was for being too fast under the safety car, Jenson got in on this one as well so that Lewis didn't feel left out.

On lap 12 the safety car came back in one more time and Jenson was handed a drive through penalty. Mark Webber was now in 9th place and trying very hard to improve. Once Jenson had completed his drive through he started to show some real pace on the intermediate tyres. Perhaps this had been a strategic master-stroke? Rubens obviously thought it was a good choice as he dived into the pits to try it out himself. Mark Webber didn't seem to be hanging about and pulled himself up to seventh. Fernando Alonso also liked the look of Button's pace, he dove into the pits for a new set of tyres as well.

By lap 19 the rain was starting to fall again as proved by Button aquaplaning towards the hairpin. It suddenly turned into an enormous downpour which bought the safety car out again to avoid any incidents. Alonso and Button both dived into the pit straight away to get back onto full wets. Sebastien Vettel followed them in next time around and thanks to the safety car not picking up the leader straight away managed to get away with only losing a place to Massa. Even that didn't last long as he also pulled in for a tyre change, Vettel gets all the breaks!

The rain was now increasing even more and  the red flag was shown on lap 25. The cars lined up on the grid Vettel in the lead followed by Kobayashi, Massa, Heidfeld, Petrov, Di Resta, Webber, Alonso, De La Rosa, Button and Rosberg. Kamui had not pitted at any point in the race and could now reap the rewards, a free tyre change and second place on the restart. The rain eventually stopped and the street sweepers were out in force to try and clear the track. The race was finally set to restart after a two hour four minute red flag delay.

The safety car led the cars off and after a few laps Kovavleinen was seen going slowly with what appeared to be a slipping clutch. He made his way back to the pits to retire and as it was announced that the safety car would come in on lap 35 D'Ambrosio jumped into the pits to go to inters. That was one  lap too early as it turned out and he got himself a drive through.

On the restart Vettel made his usual break for it and Kobayashi was too busy defending from Massa to worry him at that point. A fair few cars dived straight into the pit for intermediates and even more did the same on the following lap, including Jenson Button. Next time the Ferraris both went into the pit and had to queue for tyres with Alonso losing out. As he left the pit he ended up in front of Button who immediately tried to get up inside coming into turn 4. Alonso wouldn't give it up though and touched Button, spinning himself up onto the kerb and ending his race. Button got a puncture to show for it and made his way slowly back to the pit once again.

The stranded Ferrari meant that the safety car came out for another run, so Vettel stuck it back into the pit for a fresh set of tyres with no positions lost, while Button found himself in 21st and last place. Another investigation announced for the Button/Alonso incident.

By lap 44 Button had worked his way up to 15th place. Kobayashi was starting to struggle and Massa was trying very hard to take his place. By lap 46 DRS was being enabled and it looked like it was becoming time to change to slicks. Webber was well within the DRS activation zone was not able to take enough advantage to make a pass on Schumacher. Lap 49 and Button was up to 12th place. Buemi was sliding all over the place and that allowed Button to take his place, by lap 50 he was up to 10th.

Mark Webber was the first man to dare to go for slicks on lap 51. Kobayashi made a mistake on the way to the hairpin and Massa got alongside him. Neither of them could get any power down on the way out of the corner and Schumacher took full advantage of the situation and passed the pair of them to put himself into 2nd place. Lap 53 and Button pitted again, this time for slicks, with Schumacher and Massa doing the same on the following lap. Massa moved onto the wet part of the track to pass a back marker, lost all traction and knocked the front wing off his Ferrari but survived to continue to the pits.

Hiedfeld hit the back of a slow Kobayashi and broke his front wing supports. On the following straight the wing fell under the car and sent him flying down the escape road. The debris on the track caused the safety car to come out once more on lap 57. The order was now Vettel, Schumacher, Webber and Button with only 19 cars left in the race.

The race restarted on lap 61 with Vettel immediately opening out a lead on the other three. They stayed in order until the DRS was re-enabled. Then the fight began in earnest, Webber was trying incredibly hard but although he got alongside Schumacher, he ran wide on the final chicane. He had to give the place back and managed to do it without losing out to Button. He tried again next time round but this time couldn't keep the car straight on the way out of the chicane and lost his place to Jenson.

Button's DRS was obviously working better than Webber's as he passed Schumacher well before the chicane and started chasing Vettel. The German had a three second lead with only four laps remaining but Button gained back well over a second on the next lap. Webber finally got past Michael on lap 67 and Button was now only 1.3 seconds behind Vettel. Button went on to set the fastest lap of the race and finally get into the DRS zone on the last lap of the race. The pressure was obviously getting to Vettel and he put a wheel into the wet part of the track and half spun allowing Jenson to sweep past into the lead. He recovered to take second place followed by Webber and Schumacher. Massa used his DRS to catch up to Kobayashi and just managed to get a wheel in front on the line.

Aftermath

An incredible win by Button who had pretty much everything thrown at him during the race. It must have been incredibly dissapointing for Vettel who only made one small error in the whole event, but it was the most costly one it could have been. After everything else working out so well it was surprising to see such a slip-up from the man who, so far this year, could do no wrong.

Hamilton seemed to be trying too hard again. He was attempting moves that few others would try but that is how he got himself a championship. When they work he is the hero of the day, when they don't, he looks a bit foolish. That seems to be the result too often in the last few races, but if they gave out points for effort he would already have the championship sewn up. I'd rather see that than too much caution any day. Button said after the race that he just didn't realise Hamilton was trying to overtake when they touched. According to the team, no hard feelings. But you do have to wonder a little!

Schumacher finally managed to produce a performance worthy of his previous career. Some are saying that DRS cost him second place, but I'm not so sure. Once he was overtaken DRS didn't seem to give him back second place or even third after all.

Button and Alonso were not given Penalties for their contact, thankfully. In an incident packed race it seemed that far too many were being given out. One that changed the result of the race would have been a step too far for what was essentially a racing incident.

Surely there is no way Valencia can top a race like this, even with DRS and Pirelli tyres? I guess we'll find out in two weeks time!

McLaren Nearly Catch Red Bull in Spain

Red Bull's qualifying pace deserted them in the main event in Barcelona as McLaren took the fight almost all the way to the front. The race was the best part of the weekend despite a DRS miscalculation by the FIA, which only proves that the Pirelli P Zero's are the biggest factor in Formula one's rediscovered excitement.

Qualifying

Saturday started badly for Nick Heidfeld after his car caught fire in the third practice session. Heidfeld pulled to the side of the track and got out safely but his car was severely damaged. The team worked as hard as they could but the limited time meant that it couldn't be repaired in time for Q1. Renault claimed that a cracked exhaust was the culprit but there seemed to be a huge amount of fire for that. It may well have been the start, but something a lot more flammable was involved to get the car burning that well.

This meant that there was one less car to beat in Q1 for the remaining drivers which should have taken the pressure off a little. But with a two second difference in performance between soft and hard tyres some of the teams were nervous enough to run the option tyre in the first session. Mercedes and Ferrari both used a set to get into Q2 which cut down on their supply for the race.

In Q2 the usual suspects quickly rose to the top of the time sheets, all of them using the softer tyres. As the end of the session closed in it became clear that Massa's time might not be enough to get to Q3 as he was pushed further and further down the order. The biggest news came from Heikki Kovalainen who put in a last minute lap to beat both Force India cars and take the last place in Q3. It was probably not the best move for the Lotus team from a race strategy point of view, but its great to see them moving up the field regardless.

Q3 was a relatively quiet session. The new tyres are forcing the teams to be very careful about using any when they don't have to. This meant that everyone would only try a maximum of one run, with Scumacher not even managing that. He went out on the hard tyre and came back in before setting a time, which gave him the choice of tyres to start the race on. Red Bull waited just long enough for McLaren to set some times before sending their drivers out. Vettel went first and embarrassed the silver cars by posting a time 0.8 seconds faster than Hamilton could achieve. Webber then went and did the unthinkable by beating his team mate by 0.2 seconds and proving once again that Red Bull are the toppest of the top teams this year. The only other real surprise came from Alonso who, this time out, got rid of his fifth place curse and beat Button to fourth on the gird.

Nick Heidfeld was expected to start on soft tyres due to his lack of running in qualifying, so it was a surprise to seem him line up on the grid on hard tyres. There was speculation that Scumacher would start on hard tyres having saved his softs in qualifying but he stuck with the more standard softs for the first stint.

Off the line Fernando Alonso got a blinder as he brilliantly managed to find a gap and slide past both Red Bulls into the lead of the race in turn 1. In the confusion behind, Mark Webber dropped back behind Sebastien Vettel and Jenson Button lost out even more badly, finding himself in tenth as the smoke cleared. The end of the lap saw Kobayashi in the pit for a new front wing and the race was underway.

The top five cars were very close as the Drag Reduction System activated on lap 3. This showed that the zone was set wrongly as the cars closed in, but didn't get alongside with the rear wing flap open. Button started his fight back regardless, pushing Felipe Massa into a few mistakes early on.

The pit stops started early with some cars coming in on lap 9 and the majority following them in on the next laps. Vettel came in on lap 10 for the first of four stops and ended up behind Button. But not for long, even without the benefit of DRS. Lap 11 saw Alonso and Webber pit in order to stop Vettel gaining too much advantage. As they came out of the pit lane the German dispatched the last of his traffic and ended up directly behind Alonso once more.

By lap 12 almost everyone had completed their first stops, except for Jenson Button and Paul Di Resta who was now up to sixth. It seemed that Button would be trying a three stop strategy despite the lack of success last time it was tried. Lewis Hamilton seemed to have the fastest car at this stage of the race, consistently posting fastesr laps than the people ahead of him.

Jenson finally stopped for new tyres on lap 14 behind some traffic, which stood a good chance of spoiling his race already. Di Resta went longest of anyone though, stopping on Lap 16. Fernando Alonso was still holding his own at the front, with Vettel and Hamilton chasing him hard but not able to make any further progress.

Vettel stopped again on lap 19 putting the hard tyres on this time and cementing the fact that he was on a four stop strategy. As Webber caught the leaders the rest of them started to pit. Alonso failed to stay in front of Vettel after his stop this time around and it seemed that Red Bull would carry on in their usual manner and dominate the rest of the race. But Lewis Hamilton was still putting in fast laps, and even though he stayed out two laps longer than Alonso, he beat him out of the pits and took second place.

By this time Nick Heidfeld had moved onto a set of the brand new soft tyres he had available and started to charge up through the standings. Mark Webber was stuck behind Alonso after a very tight pit lane race and despite having the Drag Reduction System available, couldn't make it past the Spaniard. Despite having massive high speed cornering pace the Red Bull couldn't make enough difference to get past in the slower sections.

Hamilton was gradually closing the gap towards Vettel now. Jenson dropped into the pits again, the three stop strategy still seemed to be working so far. The new tyres also allowed him to start catching up with Alonso and Webber's fight. Webber eventually got close enough to throw himself down the inside and past, only for Alonso to switch back and regain the position at the next corner. Meanwhile Vettel dropped into the pits for yet another set of tyres.

Felipe Massa slowly slid down the order and now his afternoon got worse as he lost the back of his car and stopped sideways just off the track. The engine was still running though and so he continued. Hamilton got a fresh set of tyres to continue his hunt of Vettel. Throughout the afternoon the two Mercedes were fighting each other hard, Michael was making sure to stay in front of his younger team mate this time out.

As the race started heading towards the closin stages, Button's tyres were still surviving, and Heidfeld was climbing further up the score sheet. By lap 48 Webber was in the pits again for a second set of hard tyres, followed by the rest of the front runners. No change in position this time around but it became clear that Vettel was not using the Kers system on the Red Bull. As Hamilton slowly caught up, Vettel's team came on the radio telling him to start using it again.

Kovaleinen came off the track up ended up against the barriers bringing out the yellow flags. Vettel, Hamilton, Button and Alguersuari were put under investigation after the race for failing to slow down in the yellow zone. Hamilton's speed kept the gap to Vettel heading down and down, but the laps were also running out. As Hamilton got into the DRS activation zone it seemed that his car was faster, but the German's defensive driving was faultless. The McLaren looked more settled and much more comfortable holding the racing line than the Red Bull. Despite this Vettel had the better drive out of the last corner and could defend into turn 1.

Felipe Massa was suffering badly by now with what turned out to be gearbox troubles, and dropped out of the race. Jenson was still keeping Webber behind at this time and with the end of the race approaching fast, it was clear the Englishman would take the last place on the podium. Hamilton meanwhile, was getting more ragged behind Vettel and couldn't make up the difference to get past. The race ended with Vettel first and Hamilton only 0.6 seconds behind. Jenson finished third with Webber taking fourth. Alonso ended the race in fifth with Schumacher finally getting a decent result in sixth followed by Rosberg in seventh. Nick Heidfeld finished a great race for him in eighth place.

The steward's investigation after the race ended up with all the drivers involved receiving only a reprimand.

The FIA did get the DRS wrong here. Almost no overtakes came solely from the system but still the race was not another overtake-less bore as usually happens in Spain. From Canada onwards there will be two DRS zones to stop this problem despite the shorter straights. But its the tyres that are really creating the change now. Pirelli have almost single-handedly revitalised Formula 1 into an exciting, dramatic race series. And the only thing that can spoil that is Red Bull walking away with every race. McLaren are closing the gap in the races. But Hispania may fix that for us, if they follow through on their threat to lodge a formal complaint against the teams using blown diffusers in Monaco. The next week should be interesting to say the least. Could we possibly have overtaking at Monaco?!

So How Come There is Overtaking in F1 Now?

2011 has seen an exciting start to the season with plenty of drama, plenty of pitstops and plenty of overtaking. This is something that has been missing from Formula 1 recently, so how come we get so much passing this year?

The FIA have been trying to get more overtaking in Formula 1 for several years now, grooved tyres, movable front wings and forcing the teams to use different tyre compounds have all been used in the past with little success. But this year everything seems to have come together perfectly to create the right conditions for lots of excitement. Strangely the few rule changes this season show that they have less to do with this increase than the FIA and its "overtaking working group" would have hoped. Lets look at the main areas.

Tyres 

Or possibly tires if you're from the USA! The single biggest change this year is the tyre supplier. Pirelli have taken over from Michelin for 2011 to outfit Formula 1 with its endless need for sticky rubber. Pirelli tells us that they were asked to provide a tyre which would provide racing like that seen in Canada 2010 and they have provided even better. There was a fair bit of concern over the life of the tyres in pre-season testing which has (thankfully) not carried over into the season itself. This is mostly down to the temperature ranges during winter testing compared to the summer racing season. But now the warmer months are starting the rubber is working just as designed.

Pirelli have created their tyres with two layers of different rubber compounds. The outer layer is the serious sticky stuff which provides lots of grip but wears out quickly. The inner layer is much more durable but doesn't provide nearly as much cornering force. This is what the teams are talking about when they say the tyres are going into "Phase 2". The stickiness has gone and its time to get into the pits and get a new set. This change in compound leads to large changes in performance happening very quickly at different times for different drivers.

Teams are also required to used two different compounds during the course of one race. Thanks to the knockout qualifying system, this means that a variety of tyres are used at the start. The lap time change between hard and soft can be as much as one second per lap. But when the softer tyre runs out of grip, the harder version still has some left, which again leads to large corner speed differences.

DRS (Drag Reduction System) and Aerodynamics

Over the last few years the bodywork of Formula 1 cars has changed quite a bit. First the winglets all over the sidepods of the cars have been removed. Then the rear wings were narrowed and the front wings widened. This was part of the Overtaking Working Group's suggestions to improve overtaking, but by itself it didn't do the job. The narrow rear wing was introduced (and the winglets removed) to reduce the turbulent wake behind the car. Air that's swirling around is at lower pressure than nice still air and so any following car would not have as much grip as the lead car. The air is still moving quite a lot even with a smaller rear wing though, so larger front wings are required to help create sort the air out for the chasing car.

To improve the situation even more the Drag Reduction System (full description) was introduced. This means that just when a driver needs less drag he can get it. The wing flattens out and the top speed of the car increases. Again a large performance difference is created, this time on the straights.

KERS (Kinetic Energy Recovery System)

The Kinetic energy recovery system has not really factored into much talk of overtaking. It would seem that because all cars have it, its not really a difference in performance. Besides which Red Bull seem to be doing quite well even though they can only get it to work half the time! KERS works by capturing braking energy that would otherwise be lost as heat, storing it, and using it to boost engine power at other points in the lap. The big trick is that it only stores enough power for around 6.5 seconds per lap. This means that a defending driver can use all his boost well before the end of the lap. A chasing driver can still have some left before the lap is over and that, once more, leads to a big difference in speed. This time on acceleration.

Overtaking and Strategy

Large performance differences mean overtaking and Formula 1 this year has seen plenty. The DRS and tyre situation has created the differences but, most importantly, created a change in the performance of the cars during the race. This means that you can't qualify on pole and have the fastest car for the entire race. Each of the cars will have some period being faster than someone else. Maybe not everyone, but someone! The big trick is to take advantage of that change.

Mark Webber showed how important that can be in China. He spent the first stint of his race stuck at the back of the grid going nowhere before a change to the softer tyre put his car back on the performance level of the front runners. The Australian took advantage of that jump in speed to quickly climb the leaderboard. Some well timed pitstops and good overtaking were all he needed to take a place on the podium.

Overtaking is not taking place in just one spot either. There were fears that DRS would mean passing at the end of the main straight and nowhere else. Some good (or possibly lucky?) positioning of the activation zone has stopped it being too much of a sure thing. With luck (always a vital ingredient), the changes can come together and provide a passing opportunity pretty much anywhere on the track. 

The excitement looks set to continue for the rest of the season. The track in Turkey provides several passing places, as we have seen in previous years, so this year should be a classic race.
