Is the Horsepower War Almost Over?
War is hell, unless it's a horsepower war, in which case it's kind of fun. For more than a decade, the cars from AMG have been on the front lines of the horsepower wars, which have seen the top autobahn rockets - most, naturally, from Germany - zoom past 300, then 400, and now 500 horsepower. But all good wars must one day come to an end, and for the horsepower wars, that day is starting to feel very close indeed. The new E63 AMG, for example, uses the same engine as the previous model (AMG's near-ubiquitous 6.2-liter V-8) and pushes its headline figure ahead by only 11 hp.
Still, we're talking about 518 horsepower here, easily enough to send this luxurious four-door sedan down the autobahn at (a governed) 186 mph. The thing is, the previous E63 AMG, with only 507 hp, was also capable of 186 mph. Evidently, at the peak of the super-sedan pyramid, there simply isn't much more performance to be had.
The goal: Better driving dynamics
Where, then, did the AMG folks hope to move the needle with this new car? "We wanted a sharper car - better driving dynamics," says Tobias Moers, head of overall vehicle development at AMG. Here again, though, we'd argue that AMG's high-volume mid-liner already made its big move in the chassis department with the switch from the old E55 AMG to the new-for-2007 E63.... Read full article
