Harnodi | 2011 Mercedes-Benz CL63, CL65 AMG Twin-Turbo Temptresses | How does one make the Mercedes-Benz CL-Class  more exclusive than it already is? If you're Mercedes, you unveil the gonzo AMG variants. Appearance-wise, changes are minimal for the 2011 CL63 and CL65  AMG, save for the addition of Mercedes' new corporate face, which includes the standard LED running-light strip and some small tweaks to the rear fascia. The big news, however, centers on the changes underhood.

Gone is the naturally aspirated 6.3 6.2-liter AMG V8 in favor of a smaller and more powerful 5.5-liter twin-turbocharged mill. In base form, this V8 cranks out 536 horsepower and 590 pound-feet of torque (increases of 18 and 125, respectively), and with the optional AMG Performance Package, these numbers increase to an even more robust 563 hp and 664 lb-ft. Sweet stuff, and when matched with Mercedes' AMG Speedshift seven-speed automatic, 0-60 runs will take just 4.4 seconds (4.3 if you opt for the more powerful setup). What's most impressive, though, is that even with this added power boost, fuel consumption has been reduced by 27 percent. The range-topping CL65 AMG will carry over its 6.0-liter twin-turbo V12, though Mercedes has managed to coax an additional 17 horsepower from it for 2011. Output for the CL65 is now rated at 621 horses and 738 lb-ft of torque.

Both AMG CLs get a host new standard equipment as well. Mercedes-Benz's Direct-Steer system is on hand, as is a new crosswind stabilization feature that alters wheel-load distribution to keep things in line during heavy breezes. From there, a new torque-vectoring brake system applies one-sided braking during instances of understeer. The full suite of Mercedes-Benz driver aids is thrown in as well, including drowsiness detection, night-view assist, active lane-keeping assist and blind-spot assist. After all, with so much power on tap, you'll need a nanny (or several) to help keep things in line. Interior upgrades are similar to what we've already seen in the 2010 S-Class.


Official pricing hasn't been released yet, but expect MSRPs to increase slightly over the 2010 models ($145,200 for the CL63 and $207,170 for the CL65). Shoppers in that tax bracket shouldn't have any trouble shelling out a few grand extra for the latest in CL-Class exclusivity.
