"We only managed to obtain the press images of BMW’s highly anticipated sport crossover but inside sources informed that it’s based on the 2008 X5 platform using the 335Ci’s 306Hp twin-turbo straight-six. As you can see from the sketches and like several other prototypes that will debut in a few days at the NY Show, the 4-seater X6 Concept is practically production-ready. Expect the road-going version to make its official premiere at the Frankfurt Show in September with sales starting the first quarter of 2008." Cit. Carscoop
