    GMC Offers A Performance Pack For Sierra AT4

      More power isn't always a bad thing


    GMC is giving its off-road oriented Sierra AT4 some more performance with a recently announced package. Called the AT4 Off-Road Performance Package, it will add a 6.2L V8, performance air intake, cat-back performance exhaust system, and a set Goodyear Wrangler DuraTrac tires with 18-inch alloy wheels. The intake and exhaust add 15 horsepower and 9 pound-feet of torque over the stock 6.2L V8 - total output stands at 435 horsepower and 469 pound-feet of torque.

    The price tag for this option is $4,940 which may put some people off. You can buy most of the parts a la carte, but as The Truth About Cars notes, it will be slightly more expensive than buying the package.

    The AT4 is aimed at the likes of the Ram 1500 Rebel to give buyers an off-road ready truck. This includes a two-inch suspension lift, four-wheel drive with a two-speed transfer case; locking rear differentials, skid plates, Rancho off-road shocks, and hill descent control.

    The AT4 Off-Road Performance Package is available now.

    Sierra AT4 Powers Up With New Off-Road Performance Package

    DETROIT — Defining the premium off-road segment, the 2019 GMC Sierra AT4 is now available with the all-new Off-Road Performance Package. The Off-Road Performance Package adds factory-installed performance upgrades that bring additional power and purpose to the Sierra AT4.

    “The 2019 GMC Sierra AT4 debuted all-new, purposeful technologies for the premium truck segment and the new Off-Road Performance Package takes it a step farther,” said Duncan Aldred, vice president of Global GMC. “It offers optimized performance, both on- and off-road.”

    The Sierra AT4 Off-Road Performance Package includes:

    • 6.2L V-8 engine mated to 10-speed automatic transmission.
    • 18-inch machined aluminum wheels with Goodyear Wrangler DuraTrac tires.
    • Cat-Back Performance Exhaust System.
    • Performance Air Intake.

    Thanks to these additions, the AT4 Off-Road Performance Package delivers up to 435 horsepower and 469 lb-ft of torque — increases of 15 horsepower and 9 lb-ft of torque over a Sierra equipped with a conventional 6.2L V-8 engine. The 6.2L is manufactured at GM’s Tonawanda engine plant in New York and was recently named a Wards 10 Best Engine for 2019.

    For 25 years WardsAuto editors have evaluated every all-new or significantly improved engine or electric propulsion system available in production vehicles in the U.S. Vehicles must have a starting MSRP less than $64,000. The editors score eligible vehicles on horsepower, torque, technology, observed fuel economy, relative competitiveness and noise characteristics.

    The Off-Road Performance Package’s upgrades build on the Sierra AT4’s distinctive formula of authentic off-road capability, innovative technology and bold design, along with GMC’s premium refinement.

    The Sierra AT4 was introduced earlier this year, and content includes:

    • Standard 2-inch factory-installed suspension lift.
    • Standard 4WD with a two-speed transfer case, locking rear differential and skid plates.
    • Standard off-road-tuned Rancho monotube shock absorbers.
    • Standard Hill Descent Control.
    • Standard Traction Select System.
    • Standard GMC exclusive, industry-first MultiPro Tailgate.
    • Standard black chrome finish on the fog lamp bezels, fender surround and grille insert.
    • Standard body-color grille surround, door handles and bumper.
    • Standard exclusive athletic interior trim elements.
    • Standard red vertical recovery hooks.
    • Available segment-first Multi-Color Head-Up Display.
    • Available segment-first Rear Camera Mirror1.
    • Available GMC-exclusive, industry-first Carbon Fiber Pickup Box2.
    • A full suite of advanced available safety features including Surround Vision, Lane Change Alert with Side Blind Zone Alert, Front Pedestrian Braking and Low Speed Forward Automatic Braking1.

    The Sierra AT4 Off-Road Performance Package has an MSRP (excludes tax) of $4,940 and is on sale now.

    Cool, so glad to see this at GMC, Wish they would put together a Hummer package that offered some of the AWESOME off road crawl capabilities. I think they need that as an add on package like this.

    I am surprised given the continuing success of the Wrangler and Jeep in general that GM hasn't come up with a competitor.  A new identity, not HUMMER..too much baggage and failure associated with that brand name.

    5 grand for intake and exhaust? Doesn't the AT4 already come with some sweet off-road tires? 

     

    What value am I missing? This looks like a raping from GM to the buyers.

    GMC is not about 'value'..GMC is about 'professional grade', so professional grade pricing...

    Yes Hummer has baggage, but the hummer package of off road capability is what GMC needs as an upgraded series of performance packages.

    That is what AT4 is for.  Unless their plans have changed, a GMC spokesmodel stated that every GMC model would get an AT4 variant.  I can't wait to see the Granite AT4 and the Terrain AT4.

    Nope not even gonna get close to the Hummer specs.

    The Hummer H3 had 4.56 on the rear axel with a 69:1 crawl ratio if you had the Manual Trans or 59:1 crawl if you had the automatic.

    The Hummer H2 had 4.10 on the rear axel with a 33:1 crawl ratio on the automatic.

    $5000 for 15 hp and off road tires and shocks seems a bit steep.  You aren't going to feel the difference between 420 and 435 hp.  And unless you are a hardcore off roader, you probably won't notice the difference in off road ability either.

    AT4 is mostly an appearance package. 15 HP? You'll never notice it when it already has 420 other horses. 

    I just thought this is like the $4,000 add on for a Lexus F-sport package, although that has no power upgrade it is all appearance.  Not worth it.

    IMO, appearance packages definitely have their place/appeal. If they didn't, every single performance package wouldn't ALSO include an appearance pack. But you'd need a min of 40 HP to ever feel it for sure.

    "Called the AT4 Off-Road Performance Package, it will add a 6.2L V8, performance air intake, cat-back performance exhaust system, and a set Goodyear Wrangler DuraTrac tires with 18-inch alloy wheels" 

    This isn't even an appearance package though. It's literally an intake, cat-back exhaust and tires for $5,000. I mean I guess you get a different set of 18" wheels.. but it already comes with 18" wheels with the AT4 on "all terrain" tires.

    The AT4 already comes with Duratracs, doesn't it?  Like the Trail Boss?  Speaking of, I looked at a Custom Trail Boss today... it is rated for 14/18 MPG... that's as bad as a Tundra... NO THANKS.

    I'm pretty sure that's correct. 

    This package just seems like a way to con the consumer out of $3500(the package is worth about $1500, imo).

      The rumors that have been swirling around for the past year have been laid to rest this morning. General Motors announced that Hummer will be returning as GMC-branded electric pickup truck boasting 1,000 horsepower and 11,500 lb-ft of torque. 0-60 mph will take three seconds. Those hoping for details about battery capacity, charging, and price will need to keep waiting until May 20th when GMC will officially show off the truck. Before then, GMC will preview the truck in a thirty second ad during the Super Bowl on Sunday.
      “GMC builds premium and capable trucks and SUVs and the GMC HUMMER EV takes this to new heights. We are excited to debut our revolutionary zero-emissions truck during the biggest night in TV advertising," said Duncan Aldred, vice president of Global Buick and GMC in a statement.
      Production will take place at GM's Detroit-Hamtramck plant, with sales beginning next fall.

      At an event in Vail, Colorado today, GMC took the wraps off the 2021 GMC Yukon and Yukon XL.  As before, the top of the Yukon lineup will be the Denali trim, but joining the Denali for the first time is the brand's new AT4 trim which is a more off-road ready version.
      The Yukon gets an all-new interior while the Denali gets its own exclusive version. The Denali instrument panel is completely new and there are also unique seats  and four color themes.  Real wood trims with a natural look and texture join with a Denali only leather, hand-stitched interior.  For the driver, there is a 15-inch diagonal multicolor heads-up display.  On the Denali, AT4, and SLT trims, there is an available power sliding center console that allow the console to slide back up to 10 inches offering a large storage area. 
      Joining the lineup is the AT4 version. All GMC nameplates except the Savanna will be getting an AT4 version by the end of this year.  The Yukon AT4 gets a unique front fascia, and body color or dark accents around the outside, and a pair of red recovery hooks on the front.  The AT4 can be ordered with a four-corner air ride adaptive suspension that can raise the vehicle an additional 2-inches. The air ride system also lowers the vehicle 0.75 of an inch when at speed and can lower the vehicle up to two inches for easier ingress and egress. 
      Also included in the Yukon AT4 are at two-speed transfer case, 20-inch wheels, traction select system with off-road mode, hill descent control, skid plats, AT4-exclusive leather appointed seats, heated steering wheel, heated and cooled front seats, and heated outboard second row seats. 
      The 4th generation of GM's magnetic ride control is available in certain trims. Also available is an electronic limited slip differential. When in 4WD low, the eLSD operates at full lock to prevent wheelslip. 
      The Yukon will offer three engine choices. An all-new version of the 6.2-liter V8 that produces 420 horsepower and 460 lb-ft of torque is a buy-up option. Standard is the venerable 5.3-liter, updated with new stop/start technology and dynamic fuel management which can allow the vehicle to run on as few a two cylinders.  Additionally, a 3.0 liter inline 6-cylinder turbo diesel joins the Yukon for the first time.  No matter which engine is selected, the transmission is a 10-speed automatic activated through GMC's new Electronic Precision Shift push-button selector. 
      Like the recently revealed 2021 Chevrolet Suburban and Tahoe, the Yukon gains 4.9-inches in wheelbase and that leads to a big increase in interior room.

      GMC had a hit on their hand when they introduced the GMC Canyon for the 2015 model year, but they've not done a lot to refresh the truck visually since then. Six years is a long time for a truck to go without a refresh, but in 2021 the Canyon will get one.
      In addition to the visual refresh, the Canyon is getting a new AT4 trim line like that of its big brother the Sierra.  The AT4 designation brings new 31-inch Goodyear Wrangler DuraTrac tires on 17-inch aluminum wheels, an off-road tuned suspension with advanced hill descent control system, four-wheel drive standard along with a G80 rear automatic locking differential, and a transfer case skid plate.  Visually, the grille is larger and there are now red recovery hooks. The seats have Kalahari stitching in AT4 headrest embroidery.
      The Denali is also getting some upgrades. The grille has been updated with a more sculpted and layered pattern. Chrome assist steps are standard along with a swath of other chrome accents. It is equipped with 20-inch diamond cut wheels and the look has been updated to match the Sierra. Inside there is now open-pore ash wood trim, aluminum trim, unique stitching, and a new cocoa/dark atmosphere color theme.  Heated/Cooled seats and a heated steering wheel are standard.
      Both trims come standard with the 308 horsepower 3.6-liter V6 or the 2.8-liter diesel with 369 lb-ft of torque.
      The 2021 Canyon will go on sale later this year.
