Report: BMW 740i With Six-Cylinder Power Coming In 2011

The BMW 7-Series is already a pretty potent performer with either the twin-turbo V-8 (750i) or the range-topping V-12 (760i). But a new report shows that BMW will be adding six-cylinder power to the 7 lineup in 2011, by way of the 740i and 740iL sedans.

The 740 will be powered by a twin-turbo inline-six, producing 315 horsepower and 330 pound-feet of torque. This is slightly more powerful than the current engine used in vehicles like the 135i and 335i, and it makes us think that the 740 will use the second-generation of the N54 engine, while smaller vehicles (like the 1- and 3-Series) will use BMW’s all-new N55 single-turbo six, set to debut in the 535i Gran Turismo early next year.

Unless Mercedes-Benz, Audi, and Lexus have plans to alter their lineups, the BMW 7-Series will be the only full-size luxury flagship available in America with six-cylinder power.
