It's being long time since i've heard anything about Gen V engine
..
I think in the begining there will be two V6 (with ~260 hp and 300 hp..no I4) and v8 (with 370 and 400+ hp). Later there will be some crazy 550+ hp version and basic engine will be replace with 4 cylinder turbocharged engine. V8 will be replaced by new gen. V.V8 with smaller displacement and same or higher HP.
Crazy version get power up.
