I'm just not excited about ///M using the same engine setup as a previous ///M car. Meaning I'll be disappointed if they put another Twin Turbo V8 in the next M5 even if they do combine it with Hybrid Assist. I guess we'll just have to see what engine the next 550i will have since we can pretty much guarantee that ///M will just rework that engine for the next M5. Lol!
