We have the full scoop on the 2011 BMW 740i and 740Li set to go on sale in the U.S. early next year. How powerful is the new inline-six? Details inside.

BMW plans to sell the 2011 BMW 740i and the 2011 BMW 740Li sedan models in the U.S.  The cars will use a six cylinder engine for the first time since 1992.

The two cars will hit U.S. showrooms in Spring 2010.

Using a 3.0-liter twin-turbo inline-six aluminum engine, the driver will get the benefit of up to 315 horsepower and up to 330 ft-lb of torque.  Under the BMW EfficientDynamics programme, the engine was designed with the concept of "virtual displacement," helping the company to develop a more powerful, more efficient unit.  The variable-cam engine also utilizes direct fuel injection and brake energy regeneration, and is mated to a six-speed automatic transmission.  Power is sent to the rear wheels.

Optional equipment on the car will include M Sport, Driver Assistance, Individual Composition, Luxury Seating, and Rear Entertainment packages.  Pricing on the 2011 BMW 740i and the 2011 BMW 740Li will be disclosed as the vehicle gets closer to a market launch.
