In the Car Magazine article that was published last month, they've stated that the new powertrain would include a bi-turbo instead of a triple-turbo (point #4):
Does this mean all bets for a triple turbo are off? I was seriously hoping for a triple turbo engine (two tiny turbos, combined with a large turbo just like the M diesel offerings in Europe). How amazing would it be having near maximum torque just off idle with a set up like this?
Could we get scott26 to confirm this? Also, since this is a next generation motor, and unrelated to the M5/M6 v8, is it possible for the redline to be substantially higher than 7200RPM as found in those?
