Auto Extreme

The El-Camino has come to life in the form of the all-new Pontiac G8 Sport Truck that will hit the market in North America in 2009. This rumor and speculations has been around for months about a G8 Ute and GM even showed the GMC Denali XT concept at the Chicago Auto Show last month – a four-door ute with a two-mode hybrid power-train that may or may not see production.

Now that the Pontiac G8 has ushered in a new era of affordable rear-wheel-drive performance at General Motors, the car-based pickup truck, or Ute as they are called Down Under, is coming back. ust like its G8 sedan sibling, the Sport Truck is based on the corresponding Holden Commodore model, which bears the “Ute” nametag in Australia.

Based on the G8 sedan, the Sport Truck has a longer wheelbase and a cargo bed (with an available soft tonneau cover). Additionally, there’s 8.5 cubic feet (245 liters) interior cargo area behind the seats. Compared to the sedan, the 118.5-inch (3,009 mm) wheelbase is approximately four inches longer and the overall length is six inches longer. The cargo bed measures at 73.9-inch (1878 mm) in length and has 42.7 cubic feet (1208 L) of space while it can carry a payload of more than 1,074 pounds (488 kg) and tow a 3,500-pound (1,600 kg) trailer.

Power comes from the same 6.0L V-8 engine used in the G8 GT that delivers 361 Hp and 385 lb.-ft. (522 Nm) of torque. The V8 is matted to a 6-speed automatic transmission and according to Pontiac; it has a 0-to-60 time of 5.4 sec. The G8 sport truck rides on 18-inch aluminum wheels with a P245/45R18 summer performance tire. An optional Sports Package includes 19-inch alloys with P245/40R19 summer performance tires.
