With the recent announcement of the new 2011 CL550 and its 4.7-liter twin-turbo V8, we can now confirm via Mercedes-Benz‘s German website that the CL63 will come with the company’s latest twin-turbo 5.5-liter V8.
The website lists the engine’s output at 536-hp, the same amount Mercedes claimed the engine could produce when it released specs on the engine several weeks back. That being said, torque should be rated at 590 ft-lbs. Mercedes will also offer an AMG Performance Package bumping power to 563-hp and 664 ft-lbs of torque.
In addition, the 2011 CL63 will do away with the old 7G-Tronic transmission in favor of the new 7-speed MCT Speedshift transmission.
As for the CL65, it also gets updates for 2011, but only mild ones in an effort to help set it apart from the CL600 and CL63. That being said it gets a slight jump from 604-hp to 621-hp.

518 horsepower and a 0-60 mph time of just 4.4 seconds!
Hot on the heels of the new E-Class, Mercedes has released details of the high-performance E63 version, which will make its official debut at the New York Auto Show on April 8th.
The new model retains the 6.2-liter V8 found in the previous generation, and gets just a slight bump (of 11hp) in performance to 518hp and 465 ft-lbs of torque. To help get that power to the ground AMG has equipped the car with the new AMG Speedshift MCT 7-speed automatic transmission, first used in the SL63. Using a multi-disc wet start-up clutch, instead of a traditional torque converter, shift times are just 100 milliseconds in “M” (Manual) mode.
Another reason for the speedy shift times is that AMG has programmed the ECU so that under full load gear shifts, the ignition and fuel injection are interrupted.
The engine and tranny combine to deliver a 0-60 mph time of just 4.4 seconds!
Oh, and the the transmission does rev match on the down shift and have a Race Start or “launch control” function.
In total the transmission has four settings: C” (Controlled Efficiency), “S” (Sport), “S+” (Sport Plus) and “M” (Manual).
The Controlled Efficiency setting also works with several other technologies to reduce overall fuel-consumption by 12 percent compared to the previous model. The Controlled Efficiency mode will give early up-shifts to keep engine speed as low as possible, while AMG has developed a way to “detach” the alternator from the engine so that it doesn’t drain power when it isn’t needed.
The body of the E63 is 17mm wider than the standard E-Class with a front track that is 2.2-inches (56mm) wider. The front suspension has been completely redesigned by AMG engineers with new control arms, wheel bearings, a new stabilizer bar. This new setup actually moves the location of the wheel to provide better handling and more negative camber.
As a result of the wider setup, the steering ratio is now 22 percent more direct and boasts a sporty 14:1 ratio.
The suspension of the E63 has been completely redesigned with a new front setup and a rear that features an AMG air suspension. The E63 also gets a variable suspension system with AMG Ride Control that allows for three different suspension settings: Comfort, Sport and Sport Plus.
Another adjustable feature is the stability control program, or ESP, which has three settings: “On,” “Sport” and “Off.” The Sport setting allows for increased slip.
For ease of use, the MCT transmission settings, ESP settings, suspension settings and AMG drive modes can all be adjusted via the AMG Drive Unit.
Other highlights of the E63 include 18-inch wheels that measure 18×9-inches up front and 18×9.5-inches in the rear with front 255/40/18 tires and 285/35/18 rear tires. The brake rotors measure a substantial 14.2-inches at each corner.
For those who demand even more from their car, AMG will offer a “Performance Package” that includes 19-inch wheels with 255/35/19 and 285/30/19 tires, as well as a stiffer suspension setup, a locking rear axle, a three-spoke performance steering wheel and a new top speed of 186 mph (standard top speed is 155 mph).
We’ll bring you more details and full specifications from the NY Auto Show starting April 8th.
