Williams to use Renault engines from 2012

Williams F1 have announced that they will switch to using Renault engines from the start of the 2012 season.

This will cause quite the case of nostalgia for the sport’s more experienced fans, as the last time Williams and Renault teamed up were the glory days of 1989-1997. In this time, the team won 5 constructor’s titles and 4 driver’s championships.

This new deal will cover 2012 and 2013. With the engine regulation change set for 2014, talks are already underway to extend the contract past this time.

Frank Williams has stated:

We are delighted and excited by our new partnership with Renault. This reunites the 
F1 team with a leading car manufacturer and complements our new relationship with 
Jaguar.

At the same time, we are grateful to Cosworth: they have been a fair and reliable 
partner both on and off the track for the past two years and we look forward to 
working with them across our business in the future.

Our previous relationship with Renault was one of the most successful in Williams’ 
history but we will not allow ourselves to dwell too much on the past.

We must look to the future and continue to re-build our on-track reputation, which 
I am hopeful that today’s announcement will help us to do.

Apart from Williams themselves, who will now use the same power plant as world champions Red Bull, the biggest winner here is Renault. The French manufacturer will now supply engines to 4 teams next year, a third of the entire grid.

On the other hand, Cosworth have now been dealt a huge blow, with Virgin and HRT now their only customers, which will do them no good for their image.

Over the last few years, it has been believed that Renault have been allowed to make minor modifications to their engine package, despite the engine freeze since 2008. These changes were to balance the power output between their engines and those of Mercedes.

However, since the refuelling ban last year, it has emerged that the Renault engine is much more conservative in terms of fuel efficiency. It is claimed that teams with Renault engines can run with 10kg less fuel than their rivals (excluding modifications which increase fuel consumption, such as hot blown diffusers).

No equalising of F1 engines for 2010

The FIA has decided that engine equalisation will not take place for 2010.

Engine equalisation is the process where all the different types of engines (4 of them next year) are balanced out in terms of performance, fuel consumption and reliabilty, by adding, removing, retuning and adjusting certain engine mechanics.

Engines in Formula 1 have been frozen (no development allowed) since 2008. However, teams  were allowed to change parts of the engine for reliabilty reasons. But, some engines had a definitive power advantage, and Renault were left behind. The Mercedes engine, for example, is believed to produce 18bhp more than the Renault engine, which is worth around to 3 tenths of a second per lap.

However, this season there will be an even bigger problem with the engines – fuel consumption. The Renault engine, if filled with the same amount of fuel as the Mercedes engine, can do 3 more laps. Because refuelling is banned for next year, it means that Renault can save around 7kg in fuel, which is a massive advantage to have. The Ferrari engines are the most thirsty engines on track, and they will be hugely disadvantaged by this.

Cosworth, as we know, will be returning to supplying F1 engines for the first time since 2006. The FIA has allowed them to develop their engine, as long as it balances out against the other teams. It is apparent that the most important factor for the engines next year will be the fuel consumption. If Cosworth fail to get their engines up to scratch, it will severely damage the Williams, Lotus, Virgin, USF1 and Campos teams.

So, if engines remain around the same as they did last year, Red Bull will be at the biggest advantage here. Their Renault engine means they have 7kg extra in ballast to move around, meaning more flexibility in their chassis design. Provided that Adrian Newey can deliver the goods, they may well be the team to beat next year.

Newey: Red Bull blocked from Mercedes engine deal

Red Bull designer and aerodynamic expert Adrian Newey claims that Red Bull were blocked from getting a Mercedes engine deal this year.

He says that Mercedes users, McLaren and Brawn, decided to block the deal.

Talking at the Motorsport Safety Fund’s Watkins Lecture at Autosport International, Newey says that the team wanted the engines because of the Mercedes teams’ performance advantage:

“The Mercedes engine enjoyed a good advantage over the rest of the field last year. The lap time difference was significant – several tenths of a second. And when you have to find that kind of performance from the chassis, that’s quite a big ask.”

“But in the end Brawn and McLaren blocked us from having the Mercedes engine.”

The team had also looked at using Cosworth engines for 2010, but decided to stay with Renault for the time being, despite reliability issues.

Engine supplier Cosworth have announced that their supplies of CA2010 engines for 5 teams were completed ahead of schedule before Christmas, and are ready to be shipped.

Mark Gallagher, Cosworth’s general manager, said:

“The first batch of CA2010 units is boxed and ready for our customers to press ahead with installation, fire-up and initial testing.”

“We’re looking forward to seeing them all on track next month since there is still a lot of work to do before the season starts.”

“After the very busy summer and autumn months when we were putting our program together it has been very rewarding to see the first engines ready for action thanks to the hard work of everyone here at Cosworth and our suppliers.”

Cosworth are to return to Formula 1 for the first time since 2006, supplying Williams, Lotus, Virgin, Campos and USF1 for next season.
