The 2011 BMW 7-Series is bringing back six-cylinder engines.
BMW confirms today that its range-topping 7-Series sedan will get two additions in 2011. The new 740i and 740iL sedans will join the existing ActiveHybrid, eight-cylinder, and twelve-cylinder models in the 7-Series lineup.
The new engines are twin-turbo in-line six-cylinders, with the short- or long-wheelbase body being the primary difference between the two. The new engine will put out 315 horsepower at 5800 rpm, and 330 pound-feet of torque from 1600-4500 rpm.
BMW does not confirm it, but the powertrain seems technically similar to the twin-turbo six-cylinder engine in today's 3-Series sedan, which would mean a displacement of 3.0 liters--not the 4.0 liters indicated by the badge. It's mated to a six-speed automatic transmission.
BMW last offered a six-cylinder in the 7-Series in the 735i model, which joined the lineup in 1988 and was sold until 1992.
The new 2011 740i and 740iL go on sale in the spring, with a long list of available features including an M Sport package, luxury seating for the rear passenger cabin, a DVD entertainment system, and individual options for leather and wood trim.
