Exactly, and probably less weight, more torque.
JB135MDCT, this news is months old. Do you really think M was going to keep the V8 now, when emissions regs in Europe and US are tightening? The best option is the the S55 engine and develop it so that it can handle about 450-475 hp, if not more. By the time it gets into the next M3, this engine will have had some thorough engineering, kinda like a 21st century RB26DETT or 2JZ-GTE...
