NEW GMC SIERRA

New GMC Sierra - GMC Current OffersIn our refusal to leave well enough alone and our unwillingness to compromise, we uncovered great capability. Our engineers applied a combination of mechanical, dynamic, and mass-reducing enhancements to give our new GMC Sierra 1500 XFE better conventional engine V-8 fuel economy than any other competitor. They equipped another with America’s first two-mode Hybrid technology to give the new GMC Sierra Hybrid a 40-per cent improvement in city fuel economy over the conventional engine and best-in-class V-8 fuel economy. The new GMC Sierra 3500HD, equipped with the available Duramax Diesel and Allison transmission, is still the most powerful V-8 one-ton. That’s technology that happens when you engineer to exceed expectations.

Now standard on all new GMC Sierra 1500 models with Vortec 6.2L and 5.3L V-8 engines is an electronically controlled 6-speed automatic that combines high max trailering with precise control. Driver Shift Control (DSC) lets you select a range of gears to suit variable driving conditions. Shift into "M" and the currently engaged gear number is illuminated, and all other gears are accessible. As conditions vary, you may change the range of available gears by simply tap-shifting the plus/minus button up or down. The 6-speed’s Tow/Haul mode reduces excessive shifting when towing or hauling a heavy load, and it automatically engages grade braking. Grade braking assists in maintaining desired speeds on downhill grades by implementing a shift schedule that utilizes the engine and transmission to slow the vehicle. Available heavy-duty cooling helps deliver improved trailer ratings on all new GMC Sierra models equipped with the 5.3L V-8 engines and the 6-speed transmission. Standard with the 4.3L V-6 and 4.8L V-8 is an electronically controlled 4-speed automatic that features overdrive for highway driving and automatic Tow/Haul mode.

Sophisticated Design Of The New GMC Sierra

The new GMC Sierra 1500 capitalizes on a wide front track and a boxed frame with high torsional rigidity. Torsional rigidity—resistance to twisting—contributes to durability and to performance. By hydro-forming the front rails, our engineers eliminated several welds, allowing for tighter packaging and improved fit at bolting points. The rear rails are fully boxed all the way back to the spare tire cross-member, where they become C-Channel. This sophisticated design helps boost payload capacity without significantly increasing vehicle weight. Ingenious hydraulic body mounts, standard on select new GMC Sierra models, securely link the cab to the frame, but in a way that isolates occupants from road (or off-road) noise and vibration. The StabiliTrak stability control system and traction control are standard on all new GMC Sierra 1500 models and select new GMC Sierra 2500HD models. The system has sensors that read the position of your steering wheel, vehicle speed, brake pressure, lateral acceleration and turning rate, then feed the data to an onboard computer.

New GMC Sierra DownloadsIf your new GMC Sierra is not responding adequately to your steering input, the computer adjusts engine speed and applies brake pressure to any individual wheel to help keep you on track. Its rollover-avoidance feature can help mitigate roll forces. Its sensors are programmed to proactively predict and help counteract vehicle "tip-up" on a flat road surface.
