The new Mercedes-Benz 2011 CL-Class is here. The 2011 CL550 4MATIC now comes with a twin-turbo 4.7-liter V8 engine, which can offer close to 429 horsepower and 516 pound feet of torque. For those who already know and those who don’t, this new version has been powered with almost 47 more horsepower and a huge 125 lb-ft of torque compared to the last version.

When we talk about extra horses it only means one thing – FAST. Thanks to all that extra torque, the CL550 4MATIC will now swallow the 62 mph distance in 4.9 seconds flat.

Wait there’s more! Here comes the big daddy – CL600. This monster weighs 4,900 pounds, has two doors and dashes from 0 to 60 in 4.5 seconds.

How does it do it? Simple. Fitted under the hood is a massive 510 horsepower, 612 lb-ft torque offering 5.5-liter V12 engine.

The car will have its live public debut at the Goodwood Festival of Speed this weekend.
