Haven't posted one in here for a while, but a quick trip to www.evo.co.uk gave me a bit of inspiration:
So what do we reckon? I'm a fan, but I think the limit has been reached in the Audi/BMW/Mercedes horsepower war. There cannot be any good reason why cars should have over 580-600bhp on the road. It would be better at 400bhp but weigh 200kg less; I think weight will be the new performance improvement headline for the next few years, especially as it goes hand in hand with better fuel economy and lower emissions.
