The Detroit Auto Show will be host to quite a lot of interesting cars, concepts and announcements. For North American BMW fans, it will also bring new and more efficient six-cylinder engines for the 5 and 7 Series. While we already covered the one for the flagship limousine, the Bavarian company has now revealed more details about the new 535i Gran Turismo.
The odd cross between a hatchback and a sedan will benefit, besides the standard 4.4-liter twin-turbo V8 which is already available on the market, from a new 3.0-liter twin-turbo in-line six unit, which is capable of 300 HP and 300 lb-ft of torque.
The new engine is also fitted with an array of technologies to make it more efficient, like the Valvetronic, and will also be coupled with a ZF eight-speed automatic gearbox, the same one used on the 550i or the ActiveHybrid 7 Series.
