75 degree V6 not a new configuration
- Thread starter mandrewz
- Start date
I was Googling around to see if it had been done before and a few bikes (Honda & KTM) and maybe Ferrari and Opel have done unusual V angle engines. I think the V4 derivative of the new NSX engine rumor for the S2000 replacement might hold water.
All Honda F1 V6 engines have an 80 degree V angle, perhaps they choose 75 degrees for packaging purposes on the NSX. However, 5 degrees should not make a huge difference based on the design parameters and application of each engine.

I imagine it was to keep the CoG low. They mentioned that in the opening presentation as a priority.
80 degrees might have been a packaging issue indeed.

I only recall Honda using Isuzu diesels in the 90's and the SLX SUV.
Anyway the engine looks extremely similar to a 80's RA168 Honda turbo F1 engine, that was '80 degree V6 (the similarity is striking)
Odd bank angle is indeed something many have tried before.

That's a good find. I'm really excited to see what this new engine has to offer! The engine tach shows a redline at 7,500 rpm, but I'm still hoping for 8,000 fuel cutoff atleast.
One thing we can all be certain of, Honda knows their way around V6 engines, NA or turbocharged.
It would be very interesting to see how much power they have wrung out of the new NSX engine during their testing regimen.
I'm sure they tested reliability and power at various boost levels.
Equally important will be all the testing they've done on intake and exhaust tuning.
It would also be nice to know the displacement, bore and stroke.
It Ted is glancing askance at a 7500 rpm redline I'm sure it's a short stroke V6 so could be a high revver.
