BMW is lobbing a speciality shot at its German rivals with another GT car. Where the 5-Series GT seems to be in response to Mercedes' peculiar R-Class, the 6-Series GT is going after the coupe/sedan class created by the CLS->ke539.

A four-door 6-Series has been an on/off rumor for a few years, but last month credible sources started the some chatter again. Now the GT seems to be a go for the next-generation 6-Series.

The exact design for the 6-Series GT still has not been confirmed. It may have four full doors, or two small rear hinged doors (similar to the Mazda RX-8). What we can expect is for the car to look like a mix of the rest of the 6-Series line, with the wider grille and headlights from the CS Concept. While the size seems to make the Mercedes CLS and upcoming Audi A7->ke1687 the GT's likely targets, the four-door, four passenger hatchback layout sound a lot like the A5 sportback.

BMW may even throw all of it’s new engine technology at this coup/sedan. It’s rumored to offer a wide array powerplants including a twin-turbo V8, diesel V6 and even a hybrid engine. Expect the GT to come about a year after the new 2010 6-Series makes its debut.
