New Bi-Turbos' for 2011

Mercedes Benz USA just announced their plan to reveal new bi-turbo engines which provide more horsepower and performance then their predecessors, while being able to offer even better fuel economy standards.  Mercedes Benz is putting these engines into production on the re-designed 2011 CL 550, CL 63 AMG, CL 65 AMG, and S 63 AMG.  Replacing a 5.5 liter V8, a new 4.6 liter V8, which produces 429 horsepower in the new 2011 CL 550.  The new engine has a twenty percent smaller displacement from the existing (2010) model.  This all amounts about a ten percent increase in fuel economy, which is a pretty impressive number considering the amount of power that the engine can produce.

The second engine that Mercedes confirmed will go into production is for the new CL 63 AMG, CL 65 AMG, and the S 63 AMG.  The AMG series is a separate division of Mercedes-Benz, that specializes in producing hand-built, race inspired engines, that pack a lot of power into one car.  The new AMG engines, 5.5 liter V8 engines feature start/stop technology and twin turbochargers and direct injection, and all of this produces 536 horsepower, a twenty percent increase in fuel economy.  Also, an new AMG Speedshift 7 speed automatic transmission will also be a new feature in the CL AMG's.  In addition to the engines, the CL-Class got a facelift with new LED daytime running lamps, LED turn-signals, and improved bi-xenon headlamps with active curve illumination.  The rear of the car also got minor upgrades such as rear exhausted incorporated into the rear bumper, as well as re-placement of the reverse lights in the trunk lid.
