In concept form, the Dodge Nitro Concept is based on the existing Jeep Liberty, a compact sport-ute known for none of the attributes that Chrysler says would make a production version "best" at everything.

The Dodge Nitro Concept is equipped with the Liberty's 210-horsepower, 3.7-liter V6 engine; four-speed automatic transmission; full-time 4WD system; 4,115-pound curb weight; and independent front and solid axle rear suspension. In the Liberty, this doesn't add up to anything "best" except off-road capability, and we doubt the 20-inch wheels and 255/50 Michelin Diamaris tires on the Nitro make that big a difference in the handling department.

In fact, press releases for the Dodge Nitro state a top speed of 108 mph, a zero-to-60 mph time of 9.6 seconds, and a quarter-mile trap time of 16.9 seconds. Maximum cargo volume for this alleged midsize SUV is a measly 66.9 cubic feet. See what we mean about a smokescreen?
