Nitro!

Beneath the squarish sheet metal, the Nitro has Jeep-sourced components that include a 210-hp, 3.7-liter V6 and live rear axle. That setup never impressed us with its performance or ride in the Liberty, and it doesn't work better here. It only takes a few miles of driving to uncover flaws, with the most obvious being the relentlessly noisy engine and a stiff, bumpy ride. On the highway the ride becomes floaty. Engine power is adequate, but a driver must prod it to keep up the pace. Vague steering and notable body lean leaves the handling less than agile.
