When we had our First Drive in BMW's new X6 Sport Activity Coupe, we didn't get the opportunity to really measure fuel consumption, since the vehicles were gassed-up when we got behind the wheel and were then refuelled during our lunch break. A glance at the on-board computer of the '35i we drove on the long route through the mountains indicated about 13.5 mpg which is nothing to write home about. The other day, BMW sent us the preliminary EPA numbers for the X6 which came in at 15/20/17mpg city/highway/combined for the turbo six cylinder model. The 404hp turbo V-8 completed the test cycles with ratings of 13/18/15mpg. When the two-mode hybrid version of the version of the X6 debuts in 2009, it will be combined only with the V-8 engine. With an expected 25 percent improvement overall, the X6 hybrid should hit about 18-19mpg combined.
