New V8 bi-turbo engine with innovative technology

The new-generation Mercedes-Benz CL-Class also assumes a pioneering role with its drivetrain. Under the hood of the CL550 4MATIC a new V8 biturbo engine with BlueDIRECT technology delivers impressive power. With its 4663 cc displacement, the eight-cylinder engine produces 429 hp so that despite 0.8 liters less displacement, it is still around 12 percent more powerful than its predecessor, which had an output of 382 hp. At the same time, torque was raised from 391 lb-ft to 516 lb-ft - an increase of 32 percent. The new engine achieves a 10-15% improvement in fuel economy and 23% improvement in CO2 emissions. The CL550 4MATIC requires a mere 4.9 seconds to accelerate from a standstill to 60 mph (previous model: 5.4 seconds). Summing up: the CL550 4MATIC is significantly more agile, torquey and thriftier than its predecessor.

The BlueDIRECT technology package of the V8 biturbo includes a series of new developments, unique in their combination. Worthy of mention among these is the third-generation spray-guided direct gasoline injection with piezo injectors and multi-spark ignition with up to four ignition sparks within a millisecond. Together both enable an innovative combustion process called "homogenous split". Other factors contributing to the exemplary low fuel consumption continue to be the consistent use of friction-optimized pistons, piston rings and cylinder barrels, the on-demand control of oil pump and the new three-phase thermal management in the coolant circuit. The luxury coupes also controls the alternator depending on the type of driving and on-board voltage. Kinetic energy is recuperated in the overrun mode.

The CL600, with its 510 hp 12-cylinder biturbo engine and 612 lb-ft. of torque remains the top-of-the-line model: it accelerates the luxury coupé from a standstill to 60 mph in a breathtaking 4.5 seconds.
