the new CLS63 AMG 6.2-liter naturally aspirated V-8 engine is an improvement over the supercharged 5.4-liter V-8 that was an AMG staple—particularly, if the new car is quicker or slower off the mark. Well, the answer is yes and no, at least on the evidence of the CLS63 AMG that we have been stylin' in of late. 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, a tenth quicker than the CLS55, but is identical otherwise up to 120 mph and shares a 12.6-second quarter-mile time. The 30-to-50 and 50-to-70-mph figures show the benefits of the supercharged motor's fatter torque curve (2.2 and 2.5 seconds, respectively, compared with 2.5 and 3.1 for the CLS63), while the extra top-end grunt of the 63 comes into play above 120 mph. By 150 mph, the CLS63 is ahead by almost a second and a half.
So, apart from marginally better performance away from a stop light and in go-to-jail-fast territory, what are the benefits of the new engine? Well, 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, not to say that the old five-speeder was bad. More important, manual shifting is now effected by a pair of paddles on the back of the steering wheel—right for upshifts, left for down—in place of the buttons in the CLS55.
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. It isn't quite as sweet a chassis as a BMW M5's, but the CLS has the advantage of a fine automatic transmission in place of the M5's clunky Sequential Manual Gearbox and a torquier, more compelling engine. Only serious AMG-heads are going to be able to spot the difference between this one and the CLS55. Discreet 6.3 AMG badges on the flanks and tail are the only real external clues, while there is a new instrument cluster & fabulous, race-car-like steering wheel. Otherwise, the gorgeous CLS shape and lush interior remain.BYMARK GILLIES
