This thread belongs in many places but the subject matter is the direction of BMW ///M, of which, I am very concerned.
So basically the web designers put the tags 550 hp and twin-scroll turbo when they did the X6M / X5M preview.
I am concerned because BMW's new head of ///M has said that they are working on a derivative of the X5M / X6M engine for the new M5 / M6. Additionaly, BMW M is looking at perhaps an I4 or V6 turbo for the next generation M3.
I have real problems with turbocharging for the M cars. Even the best turbo motors today have turbo lag and like most M people, I love the engine comes alive near the redline (where the engine spends its time in acceleration). With turbocharging, even the great N54 wheezes at high rpm.
This means our cherished M cars are going to feel like AMGs which is rubbish.
Write BMW, this is going to be awful.
