Chevy Colorado, GMC Canyon get updated tachometers due to graphical error

After James Bearing bought a Chevrolet Colorado, he noticed a discrepancy between the truck's spec sheet and the truck's tachometer: Chevrolet said 3.6-liter V6 in the little pickup produces 305 horsepower at 6,800 rpm, but the the tachometer indicates a redline at 6,500 rpm. So either he wasn't making as much power as he was promised, or the tachometer display was incorrect. Bearing said he asked Chevy about it but got no response. Until now. A General Motors spokesman said the rev limiter is indeed set for 6,800 rpm, but the tach graphics "are slightly off" in the Colorado and the GMC Canyon, and submitted an SAE horsepower certification to back him up. If you're wondering how such a thing got past quality control... well, let's just say you're not alone. GM is going to fix "the graphics on future trucks," which makes it sound like Bearing will just have to learn to live with the indicated redline he's got. He could always pretend he's driving a sleeper, with four more ponies waiting to be unlocked in the danger zone for those who dare.

2015 GMC Yukon and Yukon XL hit the floor at LA

The middle child of General Motors' trio of truck-based SUVs, the GMC Yukon and long-wheelbase Yukon XL, received their auto show debut at today's 2013 Los Angeles Auto Show. Showing off a bigger, bolder look, particularly on its Denali trim, the Yukon sports prominent chrome grille instantly identifies GMC's new top-end SUV.
The Yukon is will come to market with a pair of engines. The base 5.3-liter V8 pumps out 355 horsepower and 383 pound-feet of torque, while the higher-end models benefit from the same direct-injected, 6.2-liter V8 as the Escalade. That engine makes 420 horsepower and 450 pound-feet of torque, with fuel economy seeing a likely boost thanks to an active fuel management system. Like the Tahoe, Suburban and Escalade, the Yukon takes advantage of a six-speed, column-mounted automatic transmission.
The cabin has seen significant upgrades in terms of materials and technology, with an eight-inch touchscreen display and IntelliLink standard in both Yukon and Yukon Denali. Fold-flat second and third-row seats come standard, while a power option is available, as well. Other techy features include active noise cancellation and standard Bose stereos.

2021 GMC Canyon AT4 Off-Road Performance Edition is ready to hit the trail

GMC introduced a more capable Canyon AT4 named Off-Road Performance Edition that gains modifications like skid plates and a beefier suspension. It can venture further off the beaten path, but it won't get there faster. Based on the AT4, which is already better suited to venturing into the woods than the standard Canyon, the Off-Road Performance Edition gains a taller suspension and loses its sizeable front air dam to offer a 30-degree approach angle. GMC knows adventurers will be tempted to put that figure to the test, so it also added skid plates made with 5/32-inch aluminum to protect the radiator, the front differential, the steering gear, and the oil pan. Full-length rock rails on both sides shield the rocker panels from expensive encounters with boulders and other obstacles. Finally, the Off-Road Performance Edition stands out from the AT4 with specific 17-inch wheels painted in gloss black, black AT4 logos, and black exhaust tips. 31-inch Goodyear Wrangler tires come standard. Changes in the cabin are limited to floor liners. Out back, the cargo box receives a spray-in liner. Don't look for Ram 1500 TRX-like performance, because it doesn't sound like GMC made any major mechanical modifications to the Off-Road Performance Edition. Power comes from a 3.6-liter V6 that sends 308 horsepower and 275 pound-feet of torque to the four wheels via an eight-speed automatic transmission and an automatic locking rear differential provided by Eaton. AT4 buyers can order a 2.8-liter Duramax turbodiesel four-cylinder with 181 horsepower and a stout 369 pound-feet of torque on tap for an additional $4,375, but there's no word yet on whether this fuel-saving engine will be available on the Off-Road Performance Edition, too. GMC's 2021 Canyon AT4 Off-Road Performance Edition will go on sale later in 2020, though pricing information hasn't been announced yet. For context, the standard AT4 costs $39,395 in its most affordable configuration.
