First-time buyers will definitely take note of the name of GMC's latest take on the Sierra- the GMC Sierra 2500HD Truck. What's the meaning of the 'HD' in the model name of this particular pickup from GMC? In the age of consumer electronics and iPods, the 'HD' clearly does not refer to High Definition as used loosely in the consumer electronics market. In the automotive sector, it's all about Heavy Duty. In short, buyers can expect that the GMC 2500HD Truck is more than just an ordinary pickup- it's a heavy duty pickup truck! This can be seen in the kind of engines that are used on the truck. Coming as standard for all Sierra trucks is the 6.0L V8 engine that packs 360 horsepower and another 380 pound-feet of torque if this is complemented by the 6-speed automatic transmission. If buyers are looking for more performance then the tougher Duramax 6.6L V8 turbodiesel engine should be ordered and this comes as optional. This engine can pack 397 horsepower and 765 lb-ft of torque. The Allison Transmission comes as a standard for the GMC Sierra 2500HD Truck, and the one that comes with the latest version of the truck is the improved Allison Transmission. This is the same transmission that drives M1 trucks so heavy duty performance is something to look forward to. Adding power to the performance of the truck is the use of the independent front suspension. This kind of suspension is better than the solid front axle. With this kind of suspension, drivers can expect improved tire-to-ground contact and better road isolation. There are dual jounce bumpers as well and these can help manage increased loads that pass through the frame and the lower control arms. There's a common thinking as well that when it comes to trucks, buyers should not expect excellent fuel efficiency. Not with the GMC Sierra 2500HD Truck; this one comes with respectable fuel efficiency. When the Duramax Diesel is tested on the road, a single tank of fuel can go for 680 miles for highway driving.
This is available in Regular, Crew Cab Designs and Extended and buyers will be given the chance to choose between the long or short wheelbase and the four-wheel drive or the rear-wheel drive version. There are four trim levels available for the Extended and Crew Cab styles, the SLE, SLT, top variant Denali and basic Work Truck. If buyers opt for the Regular Cabin, the options come in SLE and Work Truck. For someone looking for top performance that can be offered by the GMC Sierra 2500HD Truck, then an order for Denali is recommended.
