This is the refreshed 2011 CL-Class, which despite the rumors, doesn't adopt the S-Class Coupe moniker as part of Mercedes-Benz's new nomenclature that started with the new E-Class Coupe that replaced the CLK. For its mid-life facelift, the CL coupe has received a mild facelift and a new bi-turbo V8 engine.

Visual updates include a redesigned front bumper housing LED strips with chrome surrounds for the daytime running lights, a reshaped hood, new headlamps and a more V-shaped grille. The LED turn indicators and position marker lamps along with the reprofiled rear bumper and newly-designed tail lamps round off the exterior changes.

Under the bonnet, there's a new 4.7-liter bi-turbocharged V8 engine with BlueDIRECT technology, which is mated to a revised version of Mercedes-Benz's seven-speed automatic gearbox. Stop-start system and brake energy recuperation technology are present too. The eight-cylinder unit produces 429HP and 516 lb-ft of torque. The CL500 requires 4.9 seconds to accelerate from a standstill to 100km/h, a 0.5 second improvement over the previous model.

The range also includes the CL600, with its 510HP 12-cylinder biturbo engine producing 612 lb-ft. of torque that accelerates the luxury coup
