Are Renaults being powered by Datsun engines?
Today looking at Formula Renault V6 Eurocup I discovered that the cars run a 3.5L V6 and not a 3L as I had previously assumed. Thinking about the Renault/Nissan association I searched for the spec's of both engines.
The Renault is a V4Y 701 from the Vel Satis and the Nissan a VQ35DE from the 350Z. Both have the same bore and stroke of 95.5mm and 81.4mm respectively, and the same compression ratio.
I take it that these are the same engine, just like the early 90's Mazda 323/ Ford Laser engines but why the different engine codes?
Further confirmation of the "same engine" theory, the Dallara Nissan World Series and Formula Renault V6 have just merged for 2005 and are to be running 420hp Renault engines (50hp up on the current Renault and 5hp up on the Nissan) in the Nissan series Dallara chassis, (Renault series runs Tatuus chassis).
So is the engine Frog or Jappo? It's not like Nissan has ever designed an engine with athletic lungs, however the VQ series engines have been in production since the mid 90's.
Who designed the engine?
Why the different engine codes?
What differences are there?
