Geneva World Debut: Mercedes-Benz CLS63 AMG and CLK63 AMG

Date posted: 02-15-2006

STUTTGART — Mercedes-Benz said on Wednesday that the upcoming 76th Geneva International Motor Show will be the setting for the world debut of the high-performance CLS63 AMG and CLK63 AMG models. The company said it would also unveil the face-lifted SL-Class and its AMG versions, the SL55 AMG and SL65 AMG. For the new GL-Class, Geneva will host the international premiere of the GL320 CDI and GL420 CDI diesel models.

The new CLS63 AMG, which Mercedes-Benz describes as a "four-door coupe," is powered by a 6.3-liter V8 AMG engine, which was developed entirely by Mercedes and AMG. The new 514-horsepower AMG power plant is mated to an AMG seven-speed transmission with automatic or manual-style shifting. The car sprints from zero to 62 mph in 4.5 seconds and has a governed top speed of 155 mph. The CLS63 AMG also has a new sport suspension.

In the CLK63 AMG coupe and cabriolet models, the AMG 6.3-liter V8 engine produces 481 hp sent to the rear wheels via a seven-speed automatic transmission. The CLK models have the new AMG suspension and new 18-inch AMG alloy wheels.

Mercedes-Benz said the GL420 CDI's new V8 diesel engine makes 306 hp. The GL320 CDI makes 224 hp. All engine versions of the GL are equipped with the seven-speed automatic, the company said.

What this means to you: It's not likely that the diesel versions of the GL will show up in the U.S. — but who cares when the high-performance AMG models are on the way?

Hmm... interesting how there's no SL63 yet.

Probably because it would make the SL600 pointless and come too close to the SL65. The next generation will likely have an SL63.

Isn't this 6.3L engine the one that was supposed to outpower the LS7 with 510HP or something? It looks like it lost quite a bit with the new SAE ratings. It kind of seems like a waste of money for MB to make so many high performance models, especially when the new engines aren't a big step up from the old ones.

Is this replacing the CLS55? The power numbers are pretty close.

I believe so. The naturally aspirated 6.3L AMG engines are taking the place of the supercharged 5.5L V8s.

The 6.3 doesn't make the same power in every application. The CLS55 made 469hp. It seems like a decent bump in power to me. It's about the same jump the GTO took when it went from the LS1 to the LS2.

Whoops, my bad. I guess I overlooked that part (just skimmed it over), but it says it makes 481HP in the CLK63. The 514 is a significant jump from 469, but if the CLS63 only had 481HP then it's rather useless, IMO.

Well, the CLK55 made 362hp. That makes for well over a 100hp leap. Mercedes is really going nuts with power.

Personally, I'll take a modded GTO and keep the change for what the AMGs go for.
