The General Motors line-up has featured trucks for more than 90 years. Along the way, the company has always looked to improve its trucks, making sure that they remain among the most competitive and, consequently, are widely distributed. The current model first came out in 2007 and, like all vehicles with a few years of experience, its time for touch-ups has come. For 2011, the Silverado and Sierra HD duo get some major – though invisible – changes, including a Duramax engine and an all-new chassis. After surveying their clientele, GM decided to modify what matters most in the eyes of heavy duty vehicle users. This trumps cosmetic changes, which ultimately are less important. What better than an Alberta road test to try out these new features?
Classic and uncomplicated style
Not everybody appreciates vehicles with exaggerated lines or an interior design that’s reminiscent of children’s toys. GM understands this and offers a simple, unpretentious interior. However, luxury and superior finish can only be seen on the better equipped versions, whereas the less expensive versions can seem a little drab – particularly since the light grey colour seems ill-suited for dirty work. Plus, the seats could be firmer, as they don’t offer much in the way of lateral support or upper-back support. Other than that, there’s adequate space in the cabin and several of the onboard features can certainly make your life a little easier. This includes the rear bench with storage space under the seat. As for vehicle versions and options, a simplification exercise is in order because the list seems endless. It’s easy to send the price skyrocketing if you let yourself get carried away with all the little extras.
As for the exterior, only real diehards will notice the differences on the 2011 version. There are new 20-inch wheels and the hood has been modified. Aside from that, GM is still using the same body because, according to the American manufacturer, clients continue to be satisfied with it. One thing is for sure, its timeless style will prevent it from looking dated too soon. If you want a more personalized look for your Silverado/Sierra, you’ll have to add on some accessories. If you plan on using this vehicle for work, adding mud guards and deflectors is recommended.
Technically new
Changing the chassis and engine while keeping the same body, now that’s not something you see too often. But why bother changing what matters least to customers? GM thinks it makes more sense to invest in the important stuff. Buyers called for a revamped drive train and better structure, and GM obliged. The chassis is more rigid, offering five times the torsional rigidity compared to before. Mounted on this structure, the new Duramax diesel engine, featuring 397 horsepower and 765 lbs. of torque, can tow up to 21,700 lbs. Working in tandem with an automatic six-speed Allison transmission, this engine serves up impressive performances. That said, it’s not quite up to the Ford F-Series with 6.7 L Power Stroke engine’s standards on 0-100km/h sprints, not that that really matters for a pickup of this calibre!
During our test drive, we noted how effective the new front suspension is, thanks to its bigger, more robust components. However, the version with double back wheels bounces less than the traditionally configured vehicle when towing. Also, the technology that compresses the engine to assist the braking makes this big daddy’s driving more reassuring – and it prevents premature wear on the brakes. Considering we calculated 15 litres of gas for every 100 km and an operating range of approximately 1,000 km, this vehicle can definitely take you on long trips without bankrupting you at the pump. And lastly, the 2011 version is more competent than ever when it comes to trailer sway control.
Conclusion
General Motors played it safe by barely touching the appearance of the 2011 Silverado and Sierra HD. However, their goal was to offer a technically interesting final product, which is just what heavy duty truck drivers need. After all, quality on the inside is what counts!
