Mercedes-Benz CLS63 AMG: First impressions!

Mercedes-Benz CLS63 AMG

Here are the first driving impressions of the new Mercedes-Benz CLS63 AMG. Enjoy!

And this thing isn’t tiny. The big coupe-like sedan weighs just over 4200 lb. Nor it is a Slim Jim, measuring 196.7 in. long and 74.1 in. wide, just about an inch wider than the standard CLS, thanks to a greater track. But as the old saying goes, this new Mercedes drives smaller than its dimensions would suggest.

There are several suspension settings—C Comfort), S (Sport), S+ and M (Manual). We’ve been through them all and settled on manual because, to be honest, it’s simply more fun. While it sometimes felt strangely loose in everyday driving, the 7-speed multi-clutch automatic is all its name would imply as we use the paddles to shift up or down…instantly.

If there was anything wrong with our Alpine-like road it was this: We couldn’t play with the outstanding V-8 as much as we’d have liked.

Why not? So much power. The 5.5-liter V-8 has direct injection and a pair of intercooled turbos to produce 518 bhp at 5500 rpm and 516 lb.-ft. of torque at 1750-5000 rpm. Not enough? There’s a performance edition of the CLS that makes 550 bhp, also at 5500 rpm, and a torrid 590 lb.-ft. between 2000-4500 rpm. Those of you who know your AMGs will note that 518 is not a quantum leap from the supercharged 5.5 or naturally aspirated 6.2-liter V-8s, but get this: Fuel economy is up by some 32 percent. Not only that, but both the 518- and 550-bhp V-8s get EPA fuel economy of 16 mpg city/21 mpg highway.
