Why Use Cosworth Over Renault (the New Gtr)

[Smurf]

From what I have read, Nissan are using Cosworth in the development of the new GTR. Although this sounds like a good move, why would they not call on the resources at Renault.

I would think Renault through their racing heritage whether formula 1 or other would be in an equal position to advise and provide this advice at a discounted price.

maybe it's more relative to the forced induction knowledge/experience that cosworth has, over renault?

more experience with 6's maybe?? maybe there were already connections with the ppl working on the engine, with those at cosworth, maybe even some JGTC connections?

i guess when it comes to specialists engine tuning, Cosworth might have more know-how - same sort of logic with going to Lotus for suspension tuning... both are up there in their respective fields...

then again, i'm probably the worst person to comment on this... maybe Justin can help out

Nissan and Cosworth have had an on-off relationship going right back to the late-80's. One well known engine developed by Cosworth on behalf of Nissan was the RNN14 Nissan Pulsar GTi-R SR20DET. As for not using Renault's assistance, I guess it's a matter of 'going with what you know' and have Cosworth on board, rather than risk building what would be - in essence - the first French engineered GT-R.

Which would be bad.....

From what ive read its more about Cosworth getting the new GTR to pass EPA regulations which wont be easy for the USA,Renault have lots of Turbo experience from the Turbo era in F1 they also won the most races in the turbo era...

i'd tend to believe in this day and age a matter of financial figures, who can offer what and for how much, and then the contract is awarded to that group. Even though Renault and Nissan share finances, their departments may still operate as totally seperate entities.

I think this is the best news I've heard all day! Cosworth would be the best people to give this task to, didn't they first develop the BOV as well?

It's not exactly like Cosworth are lacking in credentials. They have done turbo all-wheel-drive road cars very successfully in the past (I'm thinking Ford Escort Cosworth when I say that).

Since it was formed in 1958 by Mike Costin and Keith Duckworth, Cosworth has become the most successful engine manufacturer in the history of Formula One, with a string of driver and manufacturer titles to its credit. In addition, it has also achieved enormous success in a variety of formulae, including IRL, Champ Car, WRC, sportscars and MotoGP.

Cosworth began life in a small workshop in London in 1958. However, things quickly grew and a move to larger premises was soon required. The company moved to north London, where it began working on the development of the Ford 105E engine. Cosworth actually achieved its first victory when Jim Clark took a win in the Formula Junior category in his Lotus 18 at Goodwood in 1960.

By the mid 1960s, the company had moved to Northampton where bigger prospects were around the corner. In 1966, Duckworth signed a contract with Ford to develop a new three-litre Formula One engine, and the legendary DFV was born. It got its first taste of victory in 1967, when Jim Clark again provided the maiden victory at the Dutch Grand Prix. The DFV, in subsequent development guises, went on to dominate the sport for 15 years and clinched 155 race wins during that time.

A host of famous names benefited from Costin and Duckworth’s approach – Jackie Stewart, Emerson Fittipaldi, James Hunt and Nelson Piquet all took championships using Cosworth engines during the 1970s.

During the 1970s Cosworth engines crossed the Atlantic to take the Indy/CART world by storm. There, the DFX version of the F1 powerplant began to take an incredible 151 race wins in a 14-year reign, culminating in ten driver’s championships and ten Indianapolis 500 victories.

As the 1980s became the 90s, Cosworth continued to provide winning power, with the Ford Sierra Cosworth RS500 taking the 1987 Touring Car world title and the Cosworth-powered Ford Mondeo winning the World titles for Paul Radisich in 1993 and 1994.

In Formula One, the DFV was replaced by the HB which won 11 races between 1989 and 1993, while Nigel Mansell’s 1993 CART championship and Jacques Villeneuve’s 1995 Indy 500 win were both provided by Cosworth power. In 1994, the Zetec V8 F1 engine was introduced and powered Michael Schumacher’s first world driver’s title. In rallying, the Ford Escort Cosworth notched up numerous wins during the 1990s and the Duratec-R engine in the Focus WRC gave Ford more success.

Bringing the story up to date, in 2004, Cosworth provided the power to 30% of the Formula One grid, as well as to the entire Champ Car World Series and the Ford BP Rallyesport Focus World Rally cars.

Did you really have to do that

[scathing]

The only good engine I can think of made by Renault is their F1 engine, which has little bearing on how to build a decent road car engine. If you look at their street cars, most of the engines are average.

Cosworth has much more experience when it comes to building streetable engines. You've got all those hot Fords (Escort, Sierra, etc) and they tend to do a lot of work for specialty low-volume British marques too, I believe.

I have seen a doc. concerning the Cosworth Empire.

Its beggining and future prospects.

The new Infinity gtr35 ...oh not skyline boys...but INFINITY, is a car designed for the USA so more

than likely will come with soft suspention a large and heavily weighted machine to

compete with the HUMMERS .

As far as Cosworth is concerned.......they have no strengths, all i saw was weakneses.

The flop is about to launch....

^^^ I also heard Nissan are designing a special 'sub- $30,000 GT-R' based on the R31 sedan just for you Tekin, complete with neons, 22inch DaVincenzo wheels, Luis Vuitton pattern crushed velvet interior and triple supercharged steam engine with 88mph speed limiter... should be good for 2006 --> 1885 times...

[700HP-GTR33]

You are just waiting for me to reply.....

Go on have your laugh....I am getting a scooter for my next ride...

This petrols is killing me.

Oh by the way ...you have to have owned a GTR before you can comment on one...

OK lets see what you have said on the other thread..

[scathing]

triple supercharged steam engine with 88mph speed limiter... should be good for 2006 --> 1885 times...

Is Carlos Ghosn also going to go to jail for selling eccies?

Rezz you should not be so unkind to Tekin, he comes from MELBOURNE, he probably has a VALIANT CHARGER at home painted that bloody awful green, with chromies.

I remember hearing something a while back in relation to a patent Cosworth has on a Zircon Sand based casting process - they were going to use it in manufacuring the new GT-R powerplant - could have had some bearing on it.

I think the moulds are made with ZS which ultimately results in the ability to achieve much tighter tolerances...
