That has got to be the most ridiculous, unnecessary and ugly answer to a question that no one on this planet has asked. The regular X6 comes with a 400 hp engine. The speed limit in the U.S. is (at most) 70 mph. What is the point of this thing?
The base engine is a 300 hp 3.0 twin
Car and Driver's observed fuel economy: 16 mpg

The 400 hp version hasn't been tested yet that I know of.
The 400 hp version gets 13 mpg in the city (which is worse than a Hummer H3). And GM cannot give away Hummer.
