RE: Nissan powers DeltaWing Le Mans bid
Discussion
The videos show it cornering at high speed without too much drama. How, I don't know!
It seems that Nissan have become real innovators and produce some very interesting cars and concepts: Recently, as well as the constantly evolving GTR, we've had the Juke GTR, the Infiniti E-merge and now this!
Who would have thought it of the makers of the Micra and Almera?

. Looks great.
Anybody got Adrian Neweys phone number? Maybe he can explain?
My understanding of this car was that it was designed with a extremely small frontal area to aid straight line speed? Which begs the question why is it open cockpit? Surely this is in turn detrimental and at odds with such a philosophy?
Furthermore, ground effect or aerodynamic grip would only be effective at higher speeds, therefore it doesn't matter how much of that you have, if you have a lack of mechanical grip it is indeed going to understeer like a b
h, what with the thin track?

Presumably steering is achieved with torque vectoring between the two back wheels (and similar with the brakes) since those front wheels aren't going to do a great deal.
You may have something there and I suppose all the weight is between the rear wheels so at the front, there is little understeer with downforce keeping it on the track? (Unless they've just photoshopped the hardware out, Balmoral?)

Not quite, more like GT speed rather than LMP. Also I thought it was a re badged RML Chevy WTCC engine and not in anyway related to the duke as the article claims?It seems that Nissan have become real innovators and produce some very interesting cars and concepts: Recently, as well as the constantly evolving GTR, we've had the Juke GTR, the Infiniti E-merge and now this!

I'm in agreement with the above logic, until someone cleverer comes along and explains how front end grip might be generated.My understanding of this car was that it was designed with a extremely small frontal area to aid straight line speed?

h, what with the thin track? My observation, however, is that the car will be able to scribe a much straighter path through the tighter corners, e.g. the chicanes towards the end of the LaSarthe lap, due to it being much much narrower at the nose.
The videos of it running suggest it doesn't fall over. No, I don't understand how either!

I can't imagine Nissan backing a project with a Chevy engine in it? At least the Inifiniti sponsorship of the Renault-powered Red Bull is within the same group!

The WTCC Chevy Cruze engine isn't a Chevy, its an RML engine.Edited by Speedy11 on Tuesday 13th March 15:15

You may well be right (although not sure how you can tell) but I did say "at high speed" rather than "at race speed".

RML have very strong connections to Nisan don't they? Meaning probably of Nissan origin for the block at least?
Not according to RMl's websiteRML said:
In 2011 RML Engines debuted the new RML Chevrolet FIA Appendix engine, a 1.6 litre Direct Injection turbo engine, the first designed from the ground up by the department. Used in the 2011 RML Chevrolet Cruze, the engine secured 1st, 2nd and 3rd in Qualifying on its first run in public before taking a clean sweep of the podium in the first race of the World Championship. This car / engine combination continues to lead the Drivers' and Constructors' World Championships in WTCC.
The turbo engine concept and castings are designed for capacities between 1.6 and 2 litres, and the first iteration went from sign-off for the project to being on the dyno in less than 8 months. This timeframe included extensive mathematical design optimisation. Although tuned to run on petrol it has been designed to run on any current type of non-diesel fuel in both direct injection and port injection formats.
