Well, it’s fast; seriously fast. What else would you expect with 604bhp and a 0-62mph sprint of 3.5sec? But more than that, it’s a fabulous engine that sounds better at half only revs than an M5 does at full chat, while being effortlessly docile to drive in everyday situations. Even the nine-speed automatic gearbox is pretty smooth. The only thing is it’s juicy on fuel, but you were probably anticipating that, weren’t you?
