BMW plans to officially introduce its new 740i and 740Li models, featuring its twin-turbocharged I6 engine at the Detroit auto show next month. The reintroduction of the 6-cylinder engine in the U.S. market for the 7-series marks the first time since it was discontinued in 1992.

With the growing trend of consumers demanding fuel-efficient alternatives to high-powered engines found in many vehicles today, BMW has decided to follow suit with its latest 7-series. The 2011 BMW 7-series will now feature a twin-turbocharged I6, capable of producing 315 horsepower and 330 foot pounds of torque.

In 740i or 740Li trim, the I6 will provide just 15 more hp and 30 more lb-ft over the turbocharged I6 engines found in the smaller 135i, 335i and 535i models.

Both 740 models will feature a six-speed automatic transmission and rear wheel drive.

Keeping true to BMW’s packaging offerings across the rest of its 7-series lineup, both the 740i and 740Li will come available with a full line of options including Premium Sound Package, BMW Individual Composition, Driver Assistance Package, Cold Weather Package, Rear Entertainment, M Sport, Luxury Seating, Convenience and Camera Package.

Pricing, expected mileage and exact availability dates have not yet been released, but the 740 is expected to be available sometime next spring.
