GMC Sierra
The 2011 GMC Sierra leads a comprehensively redesigned lineup of trucks with a powerful diesel engine.
Sierra’s new 6.6-liter turbo diesel delivers 397 horsepower at 3,000 rpm and 765 lb.-ft. of torque at 1,600 rpm. A larger, 36-gallon fuel tank and fuel economy improvements allow up to 680 miles between fill-ups.
With nearly 1.3 million Duramax 6.6L engines produced since 2000, they have proven exceptionally durable and dependable. GMC backs the 2011 Sierra HDs with a comprehensive five-year/100,000-mile powertrain warranty.
The new Duramax 6.6L also features quieter operation.
Along with quietness, Sierra HD models are designed for work. The interiors feature numerous storage compartments, providing covered access for everything from work gloves to laptops. For those who use their truck as a mobile office, Sierra HDs deliver with available mobile WiFi, USB connectivity, Bluetooth connectivity, XM Satellite Radio and a navigation system. Multiple charge points enable multiple electronic devices to operate simultaneously, Sierra HDs are ready for the long haul. Sierra has a maximum towing capacity of 15,600 pounds – that’s enough to tow a 34-foot-long, three-axle travel trailer.
Longer wheelbases and wider front/rear tracks enhance the ride and handling characteristics of the Sierra 3500HD, which we test drove, giving them a greater feeling of smoothness and control.
The longer wheelbases and wider tracks are complemented by the new, stiffer frames, new jounce bumpers, shock mounts and hydraulic body mounts to provide a solid, smooth and isolated driving experience. New shocks were specially valved to support the new trucks’ weight ratings, while balancing excellent ride characteristics.
Also enhancing the driving experience is a revised steering system designed to support the trucks’ greater front gross axle weight rating. It includes a new, larger steering gear, power steering pumps and linkages.
The iconic four-bar, chrome grille with round air inlets distinguishes the Sierra HD on the outside, along with body-color bumpers, chrome door handles, chrome accents and 18- and 20-inch polished forged aluminum wheels.
Sierra 3500HD models have a comprehensive roster of safety features and functional technologies that include:
• StabiliTrak electronic stability control system on all single-rear-wheel models;
• Larger, four-wheel disc brakes with standard four-wheel ABS;
• A new high-strength steel tubular frame cross member that enhances safety and improves crashworthiness;
• Available rear backup camera;
• Segment-exclusive OnStar 9.0;
• Trailer sway control system on all single-rear-wheel models;
• Hill start assist (standard on single-rear-wheel models);
From the available remote starting feature to the unimpeded access offered by the 170-degree-opening rear access doors on extended cab models, the 2011 Sierra HD models reflect the professional grade blend of refinement and functionality for which GMC is known.
