TLC generally uses Chevrolet V8 engines to power its off-roaders, but this one uses a 4-cylinder International engine that runs on biodiesel. It gets 25 to 30 miles per gallon, according to the company.
The Icon is made for serious off-road use, according to The Robb Report, not highway cruising. And it doesn't come cheap. Sticker price for this model is $101,700.
