X5 M fuel mileage posted from PDF release - Amazing for the power output

[spmd11]

Guys,

Saw this in the PDF press release. It's showing X5 M:

Fuel Consumption in EU Cycle
Urban ltr/100 km 19.3 19.3
Extra-urban ltr/100 km 10.8 10.8
Combined ltr/100 km 13.9 13.9
CO2 g/km 325 325

According to wikipedia:

To convert between l/100 km and miles per U.S. gallon, divide 235.2 by the number in question. For miles per imperial gallon, use 282 instead of 235. For example, to convert from 30 mpg (U.S.) to l/100 km, divide 235 by 30, giving 7.83 l/100 km; or from 10 l/100 km to mpg U.S., divide 235 by 10 (23.5 mpg). To convert from l/100 km to km/l, divide between 100 and calculate the reciprocal of the result.

So, for highway, divide 10.8 into 235 and you get 21.75 mpg. Combined city/highway is 16.9 mpg. Pretty darn good! And better than my 4.8!
I wonder if the direct injection is a factor in the improved efficiency.
