Well… Merc has 6L V12 TT… BMW should respond to that … if they are going to go turbo.
600HP M5 or its fucking worthless
Not for much longer…
While the Diesotto sits at the lower end of the engine spectrum, Autobild is reporting that Mercedes has cancelled plans for a future V12 engine codenamed M295 and will instead develop a new twin-turbocharged V8 powerplant. The M295 would have replaced the current M275 family of V12s but instead Mercedes will launch two new turbocharged V8s, with four different power levels.
