I think I want myself a Tesla. LOL
In real world driving, Model S will always be quicker and more responsive than the M5. That is, unless you don't mind sitting at a stop light with the bloody engine revving at 3,500 rpm in launch control mode while passersby give you the finger.
ICE cars have to be "launched" at their peak rpm. Electric motors give you maximum power every time you step on it.
