Leaked BMW Competitive Analysis Gives Peek at Diesel OptionsBen Wojdyla1/21/08 1:45pmFiled to: LeakyBmwBMW X6BMW X6 DieselDieselX613EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkSomething fishy just leaked onto the Bimmer-centric site edBMW. It's a supposedly leaked document that compares the freshly unveiled BMW X6, Porsche Cayenne, and Range Rover Sport head to head, oh yeah, and also provides info on two diesel variants. The comparo makes it look like the new X6 is a gift from the acceleration gods, dutifully spanking both competitors (which strangely do not include the Audi Q7) in both acceleration and fuel consumption. We'll take that with a grain of salt and wait for independent testing first. It's that part about two different diesels that's interesting though.
