GMC introduces off-road performance package for Sierra AT4

GMC is giving its off-road-focused Sierra AT4 pickup even more performance with some factory-installed upgrades. The package is called the AT4 Off-Road Performance Package. With it you'll get the 6.2-liter V8 engine upgrade, cat-back performance exhaust system, performance air intake and 18-inch aluminum wheels shod in Goodyear Wrangler DuraTrac tires. The upgraded performance comes in the form of extra power. Thanks to the bolt-ons, you gain 15 horsepower and 9 pound-feet of torque over the 6.2-liter in stock form. This increases output to 435 horsepower and 469 pound-feet of torque — not too shabby. This package is priced at $4,940, and available for order now. That's a hefty price for what amounts to some minimal bolt-on modifications you could easily do yourself. However, buying it through GM means you get to keep your warranty in place. The Sierra AT4 already has more off-road features than a normal Sierra 1500. You're getting a two-inch lift, four-wheel drive with two-speed transfer case, locking rear differentials, skid plates, Rancho off-road shocks and hill descent control. Both the wheels and tires are available as options already, but this package just bunches related stuff together. It'll be up to you to decide if an exhaust and intake are worth the extra dough.

GM recalls 3,300 pickups and SUVs for new ignition-switch issue [UPDATE]

UPDATE: A statement from GM about the recall has been added below. The exact total of vehicles affected is 3,296, including 3,073 of them in the US. General Motors isn't letting an ignition-switch problem grow into a massive scandal again. The automaker is recalling about 3,300 North American trucks and SUVs. They are: the 2014 Chevrolet Silverado and GMC Sierra and the 2015 Chevy Suburban and Chevy Tahoe, as well as 2015 model heavy-duty pickups, the Detroit News reports, citing an Associated Press story. The issue appears to have been caught fairly quickly. In this case, the keys can get stuck in the "start" position and then slip to "accessory" if bumped. This is because the ignition lock gears have an outer diameter that's larger than the specifications allow. When that happens the engine shuts off, and the driver loses assistance to the steering and brakes. The airbags might also be affected. The vehicles get a new ignition-lock housing to fix the problem. According to the Detroit News, an employee who experienced the problem with the switch discovered the issue, and this person then let officials at the automaker know as part of the Speak Up for Safety program. A total of five reports of the fault were discovered. However, there are no cases of injuries or crashes. The claims to the automaker's resolution program eventually tallied that GM's previous ignition switch problem included 124 deaths and 275 injuries. The company also had to recall millions of vehicles and pay significant fines to the US government. GM Statement General Motors is recalling 3,073 full-size trucks from the 2014 and 2015 model years in the U.S. Some of these vehicles may have an ignition lock actuator gear with an outer diameter that exceeds specifications, which may make turning the ignition key difficult. The ignition key could get stuck in the "start" position. This may be more likely at higher interior ambient temperatures. If the vehicle is driven with the key stuck in the "start" position, and the vehicle experiences a significant jarring event or the vehicle's interior temperature cools, the ignition lock cylinder could move out of the "start" position, rotate past the "run" position, and move into the "accessory" position, leading to loss of power steering assist, power brakes and potentially air bag deployment in certain crashes. Dealers will replace the ignition lock housing.

2019 GMC Sierra AT4 gives Raptor and Ram a new off-road rival

The 2019 GMC Sierra AT4 blends off-road hardware into a modern, thoroughly updated pickup truck that doesn't skimp on power, luxury, or safety equipment. From its higher suspension setup to its available carbon-fiber cargo bed and the new MultiPro tailgate, the 2019 Sierra AT4 is a direct shot across the bow — or cargo beds, if you prefer — of staunch rivals like the Ford F-150, Dodge Ram and Toyota Tundra. Revealed tonight in New York City, ahead of this week's New York International Auto Show, the truck may seem to be in a strange setting. Then again, with the amount of tire-swallowing potholes currently scattered around the Big Apple, a rugged truck like the Sierra AT4 could be the perfect vehicle for either off-road excursions or an especially bumpy commute. Riding two inches higher than the standard 2019 Sierra, the AT4 comes with standard features like all-wheel-drive with a two-speed transfer case, locking rear differential, Rancho monotube shock absorbers designed specifically for off-roading, along with skid plates and 18- or 20-inch alloy wheels fitted with all-terrain tires or optional, mud-loving Goodyear Wrangler Duratecs. Hill descent control and GMC's Traction Select system are also standard. The latter of these two lets the driver choose between preset drive modes, suitable for various types of terrain and weather conditions. The system then adjusts throttle response, shift points, and the electronic stability control according to each mode. Related: 2018 GMC Sierra 1500 buying guide "The 2019 Sierra AT4 is designed for the customer who wants an elevated presence on the road and the capability to venture off life's beaten path," said Duncan Aldred, vice president of Global GMC. "It's also the beginning for the AT4 brand, which will be seen on every vehicle in our lineup in the next two years." Based on the new 2019 Chevrolet Silverado, the GMC Sierra (including the AT4 model) looks to stand out from its corporate cousin in terms luxury touches, along with some subtle exterior details. For the AT4, these visible differences include a body color grill surround and bumpers. Meanwhile, the inner grille, front fog-lights and faux fender vents feature a black-chrome finish. It's not flashy, which is probably exactly what GMC wanted for its upscale truck. The standard engine is a 5.3-liter V8, though buyers can choose an optional 3.0-liter turbo-diesel inline-six or 6.2-liter V8.
