GM's has been working on hybrid versions of their large SUV's, and the technology is now making the jump to pickup trucks. The automaker has announced the upcoming availability of the GMC Sierra Hybrid. The 2009 model will offer its buyers the power of a hefty six-litre engine, combined with a 25 percent reduction in fuel consumption and a 6,100 pound towing capacity.
All-electric driving is possible at speeds under 30 miles per hour, courtesy of GM's new Two-Mode hybrid drive system. Additionally, the 6.0 litre V8 engine employs some fuel-saving technologies of its own- including Late Intake Valve Closing (LIVC) and Active Fuel Management to de-activate cylinders when appropriate. There's even a specially tuned exhaust system that takes the hybrid powerplant's unique characteristics into consideration.
GM says the Sierra Hybrid will allow owners to realize a fuel savings even when the truck is fully loaded or towing a trailer. It will be sold on crew-cab bodied trucks in two and four wheel drive. A stability control system, trailering package and locking rear axle are standard on hybrid models.
"The Sierra Hybrid represents GMC's commitment to engineering excellence, delivering a fully functional truck that offers a significant improvement in fuel economy," said Jim Bunnell, GMC general manager. "Sierra Hybrid will deliver fuel economy that is expected to be the best in the full-size pickup segment, exceeding the current mileage leader - the non-hybrid Sierra."
Sierra Hybrid goes on sale towards the end of this year.
