With its 4,663 cubic centimeters of displacement the new V8 biturbo engine in the 2011 Mercedes-Benz CL550 4MATIC features BlueDIRECT technology and delivers impressive power. 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. At the same time, torque was raised to 516 lb-ft – an increase of 32 percent. The Mercedez-Benz CL550 4MATIC requires a mere 4.8 seconds to accelerate from a standstill to 60 mph. In summary, the 2011 CL550 4MATIC is significantly more agile, torquey and fuel efficient than its predecessor.

The BlueDIRECT technology of the V8 biturbo includes an impressive combination of new developments such as third generation spray-guided direct gasoline injection with piezo injectors and multi-spark ignition with up to four ignition sparks within a millisecond.

The new engine in the 2011 Mercedes-Benz CL550 4MATIC is mated to a seven-speed automatic transmission which has undergone significant revision, while V12 models retain the proven five-speed automatic transmission due to their extremely high torque at low engine speeds. The DIRECT-SELECT lever on the steering column enables the driver to select “P”, “N”, “R” and “D” by nudging the selector. The operating commands are transferred electronically by wire.

A new hydraulic circuit and optimized torque converter characteristics also help to improve efficiency and performance. A further consumption-cutting measure is a new lower-viscosity automatic transmission fluid (ATF), which has a longer life yet the same cooling performance. As a result, the 2011 Mercedes-Benz CL550 4MATIC only needs a transmission fluid change every 78,000 miles.

The optimized electrohydraulic control unit of the transmission and new reducedfriction materials in various parts of the transmission in combination with optimized software provide greater shifting comfort.
