What, another Sport Utility Vehicle? Yes, it's true. In the wake of the lackluster sales totals for its Aztek crossover wagon, which drew more derision than praise for its idiosyncratic design, Pontiac took a more traditional path with the Torrent. Pontiac's newest Sport Utility Vehicle is structurally related to the Saturn Vue and the more recent Chevrolet Equinox, based on a car rather than truck platform. Compact but sizable like its GM siblings, the Torrent also uses a V6 engine and five-speed automatic transmission. All-wheel drive is available. The all-wheel drive system works automatically to enhance traction on slippery surfaces, but it lacks low-range gearing so beloved by serious off-roaders.
