The Pontiac Torrent is a sport utility vehicle (SUV) that was offered as an successor of the discontinued Pontiac Aztek. Replacing the U-body Aztek as the company's crossover SUV for 2006. The Torrent was essentially a Chevrolet Equinox on the Theta platform. The Torrent was introduced at the 2005 Los Angeles Auto Show and went on sale in late summer 2005.
The Torrent shared its basic body structure and mechanicals with the Equinox; however, the Torrent had a different front and rear end which makes it appear like a Pontiac rather than a Chevrolet. The suspension was also modified to be firmer and sportier and was dubbed FE2. Finally, the electronic power steering was also recalibrated to deliver a firmer, less artificial feel. The Torrent shared the Equinox's 185 hp (138 kW; 188 PS) 3.4 L V6.
