Mercedes CL63 AMG and CL65 AMG Break Photographic Cover

We now have first looks at the two 2011 Mercedes CL models that we've really been waiting to see: the CL63 AMG and CL65 AMG. With the front end of the standard model firmed up, there isn't the massive visual difference there used to be between that one and the AMG versions. The CL63, riding on 19-inch wheels, gets the necessary aggression added to the lower front dam, losing its chrome accent and getting mesh instead. Sharper side and rear skirts maintain the anger, but out back AMG's trademark twin oval pipes have been replaced with squoval-like tips shaped to fit the cutout. Under the hood is said to be a 5.5-liter, twin-turbo V8 with 544 horsepower and 590 pound-feet of torque – a full 26 ponies more than the outgoing 6.2-liter.

The CL65 gets 20-inch wheels and puts some of that chrome back, applying a strip to the center of the front air dam and rear diffuser so you can tell it apart from the CL63. Or, more specifically, so people can tell your boss' CL car from yours. It keeps the joined oval pipes we've seen on 65-series AMG cars for a few years now. Under its hood resides the 6.0-liter, twin-turbo V12 biturbo giving a stout 630 hp and 737 lb-ft. Those are the kinds of numbers to make you want to throw your hands in the air and wave them like you just don't care – but in a classy, CL way, you know...

Looking over the pantheon of fast cars around the world, Mercedes-Benz and its AMG-tuned models are nearly always somewhere near the top when it comes to quickly accelerating machines. But there's always room for improvement, right? Enter Renntech, the Florida-based tuning company that's been eking more and more power from the German automaker's wares for over 20 years.

Renntech just informed us of two new world records that its vehicles were able to set, the first by a customer and his CL65. The powerhouse machine used its ECU/TCU upgrade, ram air system, intercooler upgrade, high-flow exhaust and limited-slip differential to good effect, hitting a quarter mile pass of 10.62 seconds at 133.7 miles per hour to earn the title of the World's Fastest CL65.

Next up was Renntech owner Hartmut Feyhl, who's modified C63 (using unknown and under-development prototype products, says Renntech) ran down the quarter in 11.6 seconds at 125.3 mph. That impressive showing was enough to earn Feyhl the Worlds Quickest Trap Speed recorded for the C63. Congrats on the effort, Renntech. Click past the break to watch a video of the record-setting CL65 as it streaks down the track.
