Re: E92 M3 Engine
The varioram, Variocam Plus tech all does not help out with the compression ratio. They have to do with optimization of the intake air only, like setting up resonance to enhance fuel mix etc. What i was wanting to know was that how come Porsche can do the 12:1 without publicizing some super tech to do it on normal fuel on a road car ...

Re: E92 M3 Engine
CaySman, Thanks for your thought on this and Phil u are more than welcome to comment too. Btw the RS4 engine compression ratio is 12:1 but of course they managed to achieve that by DI technology. Btw I am very impressed by how smooth the Audi V8 engine is when you pull it to the redline of 8250rpm...........I am surprised as Audi are not well known for making good NA engine in the first place. In addition, the it is very light weight too. If I rem correctly it shld be about 20-25kg heavier than the new BMW V8. Anyway, cant wait to see and try the new m3 engine. It will be a gem of engine.........

Re: E92 M3 Engine
I believe that the technology to do it is already out there... efficiency of engine design is also very impt. Besides, look at Ferrari and Lambo... they are also about the same in terms of compression as well and i don't think that they use any special tech as well.
Only thing I can think of for why most car builders don't do it is because of cost and fuel economy... so its not a matter of not being able to do it, it more like whether they want to do it or not.

Audi engineers left n joined BMW M, and vice versa?:juggle:
Wah lao, now S5 got V8 twin turbo. Another gud example of car industry u copy my tech I do likewise. I still maintain that the day when BMW M start using turbos will happen before I retire to my coffin.
