Just wanted to share some info.
The next gen F80 M3 will have a triple turbo setup with an I6 configuration. The triple turbo will be a combination of conventional turbos and introduce the world's first electrical turbos in a car as well.
What we don't know is whether it will be one small electric turbo combined with a conventional twin turbo setup, or if it's going to be a twin electrical turbo setup with one large conventional turbocharger.
This is significant because it will be the first car to completely eliminate turbo lag from turbo charged engines. The electric turbos spool up instantaneously just above idling rpms providing immediate torque. It other words, we could possibly see maximum torque developed around 1000rpm. This would give the illusion of driving a far more powerful car while puttering around town at low rpms. The torque curve from 800-2000rpm could very well be putting out as much power as a conventional naturally aspirated engine in the vicinity of 600hp. This would give the the feeling of driving a much more powerful engine at very low RPMs which is amazing in traffic.
If we have this electric turbo with a conventional twin turbo setup, we could see remapping easily boosting the 440-450hp the F80 M3 will have to the 500-530hp range.
The S65 V8 is amazing, but once we're given the exact details, I don't think M3 drivers will hesitate jumping to the next car. Minus the exhaust note, the new engine will vastly outperform our current M3s.
Don't ask where I got the information from, that I can't disclose.
Enjoy!
