The Formula One Teams Association (FOTA) has unveiled a raft of changes aimed at reducing the sport’s carbon footprint. The teams have long been under pressure from sponsors who want to be associated with a ‘green’ product and following the results of an environmental research analysis conducted by Trucost, FOTA believes it can cut emissions by over 12 per cent before 2012. According to the report, Formula One teams’ CO2 emissions hit 215,588 tonnes in 2009 of which 0.3 per cent came from fuel emissions during racing and testing. “It has already been possible to reduce Formula One’s total carbon More…

Mark Webber has revealed what was going through his mind as he experienced the worst accident of the season so far. And he has revealed that the chassis involved was the car which won the Spanish and Monaco Grands Prix. Webber hit the back of Heikki Kovalainen’s Lotus on the run to Turn 12 when he was travelling at 300km/h. Webber had recently pitted after a poor start which dropped him from second to ninth place. He was fighting with Kovalainen for position, not lapping him. The car flew through the air and was badly damaged, although it saved his More…

This weekend’s European Grand Prix at Valencia is a significant event in the story of the season from a technical point of view as it was the race where many teams unveiled a device which copies the Red Bull’s “blown diffuser”.

Last year three teams started the season with a double diffuser and, after establishing the legality of it, the rest of the field was forced to follow suit, including Red Bull. This year’s “must haves” so far have been the McLaren F Duct wing and now the blown diffuser. Red Bull is the pioneer and Mercedes, Ferrari and Renault have followed them this weekend. McLaren and Force India are due to follow at Silverstone.

On the grid this season the Red Bull mechanics have been carefully masking the diffuser from view. Although they do have something interesting to hide, in F1 this is often a bluff, indicating that the most interesting part of the car is somewhere else, but they want you to focus on the diffuser!

A blown diffuser is basically a way of using the exhaust gases to interact with the diffuser, which sits at the back of the car at the end of the floor. There are two main purposes for this;

* to try to move the wake from the rear wheels outwards where it will cause less disturbance

* to re-energise the low pressure air at the very back of the diffuser to create more rear downforce.

Rear downforce is important for driver confidence, if the driver feels good rear end stability he will push harder, so the gain on the stopwatch from this kind of development is often not what a simulator tells you it will be, but what the driver actually delivers from it.

The irony is that blown diffuser is not a new concept, unlike F Duct wings or double diffusers. Renault had one in the early 1980s, Frank Dernie put one on the Williams of Nigel Mansell in the mid 1980s and they were common from 1985 onwards. Adrian Newey’s team at Red Bull didn’t invent it, they revived it. The early ones were crude in that the rear of the car often became less stable when the driver lifted off the throttle. Everyone knows a but more about the science now.

They went out of the sport in the mid 1990s due to a change of wording in the rules, but Newey felt that the current rules would make it worth trying again.

The blown element operates independently of the “double” element of the diffuser and whereas double diffusers are banned from next season, the blown diffuser is here to stay.

The Ferrari’s exhaust exits have been moved from the high exit in the top bodywork, which they pioneered in the early 2000s, to the low exit near the floor to feed the diffuser. They stop slightly shorter than the Red Bull ones.

Low exhausts heat everything up in the area behind them and there is a risk here. Less widely reported, there was a new Ferrari gearbox this weekend, only on Felipe Massa’s car, designed to raise the pick-up points of the lower wishbone, in order to keep it away from the hot gases from the low exhausts.

Keeping temperatures under control is important and it was intersting to see a series of red stripes on the rear side section of the Ferrari diffuser. These stripes are of a special paint, which changes its colour in relation to the different temperature of the surface where its applied. In this way the Ferrari engineers could see which part of the diffuser reaches too high a temperature due to the hot gases directly blowing on them.

Ferrari’s update also includes new cooling ideas in the radiators and bodywork for the series of warm weather races coming up in the summer, as they have had problems with the engines in hot countries earlier this season.

This is an important update for Ferrari, who started the season as the pace setters but then lost ground as they got bogged down with developing the F Duct rear wing at the cost of other avenues. Meanwhile McLaren, Mercedes and Renault all stole a march on them.

Renault also had significant upgrades, including the blown diffuser. In this illustration by our technical artist Paolo Filisetti, you can see the old style high exhausts at the top and the new low style ones at the bottom.

Renault continue to push hard, they brought the 22nd iteration of their front wing to Valencia, the ninth race of the season.

And finally Lotus had a good qualifying session in Valencia, with Jarno Trulli the fastest of the new teams, increasing the margin over the other new teams to 1.4 seconds. That said the gap to the slowest of the established teams, ironically Kobayashi’s Sauber, had also grown to over a second.

One key update for Lotus this weekend was a new front wing solution, which owes a lot to design ideas on last year’s Toyota. Many of the engineers at Lotus came from Toyota so this is not altogether surprising.

One of the features of the European Grand Prix was Fernando Alonso’s anger at the actions of Lewis Hamilton when he safety car was deployed and at the length of time it took for the stewards to deal with it. Alonso has tonight accused the stewards of “manipulating” the race, while Ferrari said it was a “scandal”. On lap 9, the safety car was deployed to neutralise the field following Mark Webber’s heavy accident. Hamilton passed the safety car, just, after the second safety car line, in contravention of the rules. The timing of the safety car going out was More…

Sebastian Vettel won the European Grand Prix at Valencia today ahead of Lewis Hamilton and Jenson Button. But the stewards had a busy afternoon, investigating ten drivers in total. It was Vettel’s second win of the season, the seventh of his career and it put him “back on track” as he said, after some races blighted with problems. Rubens Barrichello capitalised on Williams’ improved performance and the safety car to pick up a well deserved fourth place, Robert Kubica was fifth and Adrian Sutil sixth.

And the result was incredibly, close, the winning prediction being just 0.007s out! Fans were asked to predict the gap between Virgin Racing drivers Timo Glock and Lucas di Grassi in qualifying in Valencia. Up to that point Glock had a 100% record of outqualifying the Brazilian, sometimes by a margin of over a second. However Di Grassi took the opportunity to turn the form book on its head and beat Glock by 0.054s – five hundredths More…

Sebastian Vettel took pole position for the European Grand Prix at Valencia, ahead of Mark Webber and Lewis Hamilton. It was a terrific qualifying session with the latest developments on several cars closing the performance gap to Red Bull and McLaren at the front. Throughout the three sessions the benchmark moved between Ferrari, Red Bull, McLaren and Renault and it was close until Q3 when the Red Bulls stretched their legs. It was Vettel’s first pole position since China and the fourth front row lock out for the Red Bull team this season. And this was at a track the More…

Fernando Alonso set the fastest time in the second practice session for Sunday’s European Grand Prix at Valencia in the updated Ferrari, ahead of the Red Bull pair of Sebastian Vettel and Mark Webber. Nico Rosberg was fourth in the Mercedes ahead of Lewis Hamilton. It was close at the front with four tenths of a second separating the first four drivers and all the indications are that this is going to be a very closely fought weekend, as the top four teams, Ferrari, McLaren, Mercedes and Renault close in on Red Bull.

The new rules regarding driver adjustable bodywork have not been well received by fans or by the F1 drivers, it seems. After the FIA World Motor Sport Council announced a new package of aerodynamic rules which will see drivers adjusting their rear wing, in a tightly controlled set of circumstances while close racing, the reaction from many fans and drivers has been negative. To reiterate, the rule is as follows, “The driver may only activate the adjustable bodywork in the race when he has been notified via the control electronics that it is enabled. It will only be enabled if More…

The FIA has taken very firm action against the USF1 team, which failed to make the grid this season as one of the new teams. They have been heavily fined and disqualified from competing in any FIA championship. The action was brought by FIA president Jean Todt, but judged by a separate Judging body under Graham Stoker. This is a departure from the old disciplinary system under Max Mosley, who was both prosecutor and judge in cases like the Flavio Briatore Singapore case. The new Judging Body of the World Motor Sport Council imposed some heavy sanctions against USF1, “a More…

It’s been a big day for the sport with the announcement that Pirelli will be the sole tyre supplier for the next three seasons and a raft of detailed rule changes, including driver adjustable bodywork and the return of the 107% rule in qualifying, to eliminate slow cars. Pirelli was the choice of the majority of F1 teams and of Bernie Ecclestone. The FIA preferred the idea of Michelin, as did McLaren and Ferrari in particular. It is quite a big ask for the Italian company, which has been active in World Rally, but has not made an F1 tyre More…

As you know, I’m a keen student of viral videos; not many people do them well in F1 and there have been plenty of poor ones. I quite like this latest effort from McLaren and Vodafone. They have done some lame ones, but the one where the two blokes build a remote control device and persuade McLaren to let them use it to drive a real F1 car was funny. This one shows Jenson Button and Lewis Hamilton, left to their own devices by their mechanics, building what looks like a 2008 McLaren from a pile of parts. There is More…

Ferrari president Luca di Montezemolo has attacked the new teams in the aftermath of Fernando Alonso losing the Canadian Grand Prix. “In modern F1 races cars with GP2 levels of performance shouldn’t participate,” he said in Gazzetta dello Sport. Montezemolo may have been referring to Jarno Trulli’s Lotus and perhaps the Hispania of Karun Chandhok, which was being lapped when Alonso lost a place to Button. “Our car had the pace to win, I hope in the future there are no more errors in lapping cars which are to our disadvantage, ” he added. “We already gave.” Ferrari have always More…

The Canadian Grand Prix was the most exciting race of the season, but also one of the most interesting tactically. There were some important decisions to be made in qualifying which affected the way teams tackled the first part of the race, but there were also big decisions to be taken during the race, reacting to events. It was clear from Friday practice that the tyres were going to be a big problem in Montreal. They grained very badly and the rears were degrading very quickly. Drivers found that once they started to go, the performance dropped very quickly. There More…

This weekend we are back in Canada after a one year absence. The track is quite different in character from the circuits we have visited so far this season and it is an interesting indication of how the cars perform in a lower downforce configuration.

Montreal is based on a series of chicanes and long straights without a fast corner to its name. As a result the cars run the second lowest level of downforce of the season, after Monza.

To illustrate the difference in detail, take a look at this drawing of the Renault front wing from Turkey and compare it with the photograph of the wing as they have brought it here.

For Montreal they have lost the small upper winglet elements because they don’t need the extra downforce they bring and they don’t want the drag. The wing keeps the same basic philosophy, particularly with the elegant multiple channels on the endplate but it is a good illustration of the differences between a track like Istanbul and a track like Montreal.

It is noticeable, talking to engineers from other teams, how Renault seems to be making small but confident steps at every race. In Istanbul the car was faster than the Ferrari and this seems to be a team on the move. If Mercedes back off on development in the second half of the season, as has been suggested, then Renault may well finish ahead of them in the championship. After their humiliations last year both on track and over the Singapore crash scandal, Renault is an increasingly confident team.

A real brake killer
One of the problems with reducing the downforce on the cars is that the drag effect is not available to the cars when it comes to braking. Montreal is easily the hardest circuit on the calendar on brakes in terms of big, punishing stops. Monaco can be very hard on brakes because they are in use all the time and never get a chance to cool down, which can tip them over the edge.

But for big, brutal stops you cannot beat Montreal and this year the challenge is even greater in the race because the cars are carrying 160 kilos of fuel at the start. We can expect some teams to have brake problems, it’s just a question of how severe they are. The driver spends 16% of the lap time pressing the brake pedal here, which is quite high in addition to the severity of the stops.

According to Brembo, there are seven stops here of which the hardest is the final chicane, where the cars brake from 320km/h to 140km/h in just over 100 metres, which is a deceleration of almost 5g. But this isn’t the one that really kills the brakes, because they have had a chance to cool down on the long straight. It’s the stop at the hairpin which kills them.

For the hairpin the cars go from 290km/h to 60km/h but because the drivers have used the brakes twice relatively soon before, the brakes are already very hot when they are applied for the hairpin. Most of the teams have larger brake ducts here this weekend to help with this problem.

Red Bull F Duct The next talking point from a technical point of view is ironically, something which isn’t here this weekend; the Red Bull F Duct rear wing. The team tested it in practice in Istanbul, but did not use it for qualifying and the race. However our technical artist Paolo Filisetti, obtained some insights into what goes on beneath the skin, which you can see in this drawing.

The main channel is the top one and this puts the air flow out through the channel in the rear of the wing. The lower one has an exit (inset in the drawing) below the rear wing, which puts the air out underneath the wing. This helps to increase the stall, in other words to increase the effect by which the wing sheds drag. It is controlled by a fluidic switch, which is essentially a switch triggered by airflow.

However after trialling it in Turkey, they decided not to bring it to Montreal, where it would have been of great value with the long straights. The team wasn’t satisfied with the way it worked in Turkey, as it drained downforce away. This is something most teams are finding as they try to copy McLaren’s breakthrough.

The specific reason why they have chosen not to even bring it here is that the rear wings are not very high downforce in the first place. Also its likely that they have been focussed on getting it to work on the kind of wing they use for 70% of the races, rather than waste resources on getting it to work on a Canada wing.

McLaren have gone to that effort and they have made a new Canada specification rear wing specifically to work with the F Duct.

There are some suggestions among engineers that taking this line of thinking to its conclusion, we might not see anyone using the F Duct in Monza. Although this sounds counter intuitive with straight line speed the order of the day, in fact the downforce levels are so minimal in the first place there is less need to shed drag.

There was some discussions about the legality of this, as in theory he gained an advantage by not carrying the fuel More…

Sebastian Vettel set the pace on Day 1 in Montreal, setting the fastest time ahead of Fernando Alonso’s Ferrari and Nico Rosberg’s Mercedes. It was a day when pretty much everyone suffered with tyre graining, due to the smooth surface of the track. The rears are suffering in particular and we could see drivers stopping twice in the race if it carries on like this. It’s been chilly all weekend so far in Montreal and although the sun made an appearance this afternoon, it didn’t pull the temperature up much, so that made the tyre graining problems even worse.
