BMW M5 versus Mercedes E63 AMG at Dunsfold
James likes it. Stig likes it. But how does the new BMW M5 stack up to Merc's E63 AMG?

So what of the BMW’s 4.4-litre bi-turbo? Is it a genuine M engine in the way that the 5.5-litre so perfectly captures what AMG is all about? Yes, it is. M doesn’t focus on the fripperies to the extent that AMG does, so it’s less shouty at start-up, but once up and running (and in both of these cars you have max torque from less than 2,000rpm) the BMW feels more focused – like it’s aiming at a point further down the road.
There’s a distant fizz of turbo noise, a bass-laden V8 rumble and then this immense surge of power. It’s totally remorseless, gaining strength above 4,500rpm and maintaining it for another 3,000rpm beyond that. It’s major league stuff – I suspect a 458 Italia would have trouble getting its nose back in front if either of these got a sniff of a lead. They make it so easy, especially the BMW. Its DSG gearbox is sublime.
