Texas Truck Mama smiled as she pulled into the driveway in her little Mini Cooper. Parked in front of her was a considerably different vehicle, a 2008 Jeep Liberty Limited sport-utility vehicle. It was about two feet longer than her Mini Cooper, several inches taller and nearly 900 pounds heavier.

The four-wheel-drive Jeep Liberty, of course, had a bigger engine -- a 3.7-liter, 210-horsepower V-6, compared with the 1.6-liter, 118-horsepower in-line four-cylinder engine in her front-wheel-drive Mini.

The Jeep Liberty, wearing all-new sheet metal for 2008, looking rugged the way a Jeep should look, barely got 21 miles per gallon on the highway, drinking regular unleaded gasoline. Texas Truck Mama's Mini got 36 mpg on the highway. And with her behind the wheel, driving like the mild-mannered elementary school teacher she is, squeezing 37 or 38 mpg out of her Mini was not uncommon, although she frequently complained about the Mini's requirement for premium unleaded fuel.
