Depending on where you live, diesel fuel can either be less expensive or more expensive than regular unleaded per litre, but either way

you can extract far more per tank than from gas. Jeep estimates that a tank of gas will last about 1,000 km, a decent range from its 78 litre tank.  In town, the Liberty's porky curb weight blunts the diesel's fuel consumption, despite best efforts to be light on the gas pedal. There's little difference in consumption than the four-cylinder model, but it quickly catches up once heading out on the open road. In my urban-biased week, I racked up over 750 km, managing a respectable 10.1 L/100 km. If you're looking at EPA figures, the Liberty CRD uses 11.2 L/100 km city and 9.0 L/100 km highway, versus the 13.8 L/100 km city and 10.7 L/100 km highway of the V6 version, some 25 percent more expensive to run than the sparkless oil-burning motor.

With all this talk of the engine, I've almost forgotten about the vehicle that it's attached to. The Liberty was restyled as a part of a mid-life update

earlier this year. While it's still recognizable thanks to its round headlamps which bulge into the hood, it now sports a revised seven-slat grille with integrated fog lamps, fender-mounted turn signal lamps and new bumpers.

Inside, newer more comfortable seats, better-positioned power window switches and an updated instrument cluster highlight the changes. The Limited trim level that my red tester came in was a classy looking vehicle, wearing a chrome-plated grille and chrome-trimmed door rub strips. This body style can carry multiple looks, from the Limited's classy urban style, to the more rugged Renegade which sports separate grille-mounted spot lamps, plastic fender cladding with faux rivets, and a roof-top spot light bar.
