This gorgeous silver on black, clean Carfax, No Accident, CLS63 AMG is ready to thunder down the road, one of the best engines ever made by AMG propels this car with a thunderous voracity. Rides, Sounds and drives fantastic. This car looks immaculate inside and out. Fully serviced by us, now is your chance to own one of these legendary rides. No smells, leaks, smoke. The 6.2-liter V-8 makes 507 horsepower in the CLS, up from 469 hp in the old CLS55 AMG. Torque is down, though, from 516 pound-feet to 465 lb-ft. More power usually results in better top-end performance, whereas more torque normally means quicker mid-range and off-the-line acceleration. To a certain extent, that's what our numbers show. The CLS63 gets to 60 mph from rest in a blistering 4.1 seconds,it sounds absolutely fantastic, especially as it nears the 7200-rpm redline. (Yeah, that's right: a 6.2 liter V-8 that spins past seven grand.) The loud, guttural growl is a bit too intoxicating, because the desire to hear a blaring soundtrack makes it all too easy to stray into triple-digit temptation. It really does pickup and go past 100 mph. The seven-speed automatic transmission is as smooth as a luxury-car salesperson, manual shifting is now effected by a pair of paddles on the back of the steering wheel—right for upshifts, left for down The vented and cross-drilled front rotors are now 14.2 inches in diameter (up from 14.0 inches) and the front calipers have six instead of eight pistons. At the back, there are 13.0-inch-diameter discs and four-piston calipers. The AMG suspension is a recalibrated version of Mercedes' Airmatic air-spring setup, which works in conjunction with the so-called Adaptive Damping System. Just like the system in the E-class, it has driver selectable settings, none of which are perfect. The sportiest setting beats you up over bad pavement and the comfiest one doesn't offer enough body control. Still, the CLS63 has lots of grip, decent steering, and is very entertaining once the traction control is turned off and the throttle is mashed. as-tested price of $100,805. It's a lot of dough, sure, but the combination of the CLS shape and the rocking new AMG powertrain make this is a sweet ride for the whizkids of this world.
