There’s no better time then the dead of winter to test AWD gas mileage. (As I write this, I’m in the midst of reviewing an AWD 2009 Mazda CX-7 GT. While the official estimates are par for the course, I’ve been able to exceed the numbers on the window sticker.) Unfortunately, AWD gas mileage is nearly always lower than the FWD variant … when all four wheels are driven, fuel economy always suffers. It comes down to simple physics. Even the best gas mileage AWDs top out in the 30 mile per gallon (MPG) highway range.

A good number of the current AWD gas mileage champs use hybrid technology. I’ve put the Lexus 400h, Ford Escape Hybrid, and Toyota Highlander Hybrid to the gas mileage test over the past year and have achieved excellent results with each vehicle.
