    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).

      GMC is taking its CarbonPro carbon-fiber bed into limited production in June for the 2019 model year and making it into its own edition.
      GMC announced the CarbonPro when the 2019 GMC Sierra Denali debuted back in March 2018. GMC says that at first, the CarbonPro edition will be available in limited numbers of Denali and AT4 models and will expand availability of the package in those trims for 2020.  
      The CarbonPro bed is lighter than a steel bed by about 60 pounds, but has much stronger durability and scratch resistance.  Carbon fiber is naturally corrosion resistant, making the GMC CarbonPro edition the most corrosion resistant bed in the industry.
      Additionally, the CarbonPro bed has best in class cargo volume, increasing the cargo capacity over the steel bed by 1 cubic foot.  Tire indentations are in place at the front wall for motorcycles, and two additional tie downs are installed on the front wall. 
      GMC tested the durability of the bed in extreme scenarios by dropping cinder blocks, 1800 lbs of gravel, and 450-pound water filled steel drums into the bed.  A generator was used to test the high heat exposure durability by aiming the exhaust directly at the corner of the bed. GMC even drove a Snowmobile with a studded track onto the bed and then accelerated at full throttle resulting in only minimal scratching of the material.
      The CarbonPro bed comes with GMC's Multi-pro talegate
      The GMC Denali and AT4 Carbon Pro Editions go on sale this summer.

      The First of GM’s All-New Pickups Posts a 20 Percent Q1 Gain
      Industry retail sales, consumer sentiment rebounding GM average transaction prices set new first-quarter company record Chevrolet Trax, Equinox and Colorado set first-quarter company sales records DETROIT — General Motors (NYSE: GM) announced today that it delivered 665,840 vehicles in the first quarter of 2019, with a selling mix of trucks, SUVs and crossovers above 80 percent. GM’s focus on these vibrant segments helped it earn the highest average transaction prices for any first quarter in the company’s history.
      The Chevrolet Trax, Equinox and Colorado all set GM first-quarter sales records and the GMC Acadia posted its best quarter ever. The all-new Cadillac XT4 was the best-selling vehicle in its segment and the Buick Enclave was up 28 percent versus a year ago.
      The all-new full-size pickups from Chevrolet and GMC are also off to a very strong start.
      “Our production launch was very smooth and crew cab sales are brisk, especially those with premium trims,” said Kurt McNeil, U.S. vice president, Sales Operations. “We look forward to improving availability of our wide-range of cabs, trim series and powertrains.”
      First-quarter 2019 average transaction prices for GM's all-new, light-duty pickups were $8,040 higher compared to their outgoing models in the first quarter of 2018, with the GMC Sierra leading the segment, according to J.D. Power PIN estimates. Combined sales of the 2019 Chevrolet Silverado 1500 and GMC Sierra 1500 crew cabs — the first of the company’s all-new full-size pickups to launch — were up 20 percent year over year. Crew-cab production mix is currently running above 70 percent to meet strong customer demand, up 10 percentage points on average from the previous-generation trucks. More than 95 percent of the all-new GMC Sierra 1500 crew cab sales are high-end trims including SLT, AT4 and Denali. Availability of all-new regular-cab and double-cab pickups was very limited during the quarter due to launch timing, but full production of all cab styles started in March and they currently are arriving in dealer showrooms.
      GM will begin the next phase of its full-size pickup truck launch in the second half of the year with the all-new 2020 Chevrolet Silverado HD and GMC Sierra HD.
      “We are bullish on pickups and expect to gain sales momentum throughout the year,” said McNeil. “We are installing capacity in Flint to build more HD pickups in total, more crew cab models, more dualies and diesel models, too, all in response to dealer and customer demand.”
      Other new models launching this year include the XT6, Cadillac’s first three-row crossover, and the CT5, Cadillac’s new luxury-sport sedan. The all-new Chevrolet Blazer is also gaining momentum, and the brand will begin national advertising for the vehicle during the second quarter as production ramps up.
      Solid U.S. Economy, Strong GM Operating Discipline
      GM sales in the first quarter of 2019 were down 7 percent year over year compared to a very strong first quarter of 2018.
      “After a slow start to the year, the retail SAAR has risen each month since January,” said Elaine Buckberg, GM chief economist. “Consumer sentiment continued to recover in March and the other key drivers of auto sales like employment, wage growth and household balance sheets are healthy. The Fed paused in raising interest rates, which eases a headwind facing auto sales. Overall, the U.S. economy is in solid shape, which bodes well for the industry outlook.”
      GM’s Commercial deliveries, which are another barometer of economic strength, grew at an average annual rate of more than 7 percent from 2012 to 2017 and were up 11 percent year over year in 2018. Commercial deliveries were close to flat to a very strong first quarter a year ago, even with limited availability of regular light- and heavy-duty pickups, and heavy-duty crew-cab pickups.
      GM has demonstrated continued strong operating discipline and is very well positioned heading into the second quarter:
      The company’s incentive spending as a percentage of average transaction price was 13 percent, down close to a full percentage point year over year, according to J.D Power PIN. GM’s per-unit incentive spending was down $175 year over year, as domestic competitors increased their spending in the quarter, according to J.D. Power PIN. Average transaction prices rose $938 to a first-quarter record of $35,881, according to J.D. Power PIN. Inventory is a healthy 818,967 units heading into the second quarter, which tends to be a strong quarter for industry sales.   QUARTER 1 (CALENDAR YEAR-TO-DATE) JANUARY - MARCH   2019 2018 %Change Volume   2019 2018 %Change Volume   Cascada 746 918 -18.7   746 918 -18.7   Enclave 12,580 9,869 27.5   12,580 9,869 27.5   Encore 24,606 25,468 -3.4   24,606 25,468 -3.4   Envision 7,623 9,696 -21.4   7,623 9,696 -21.4   LaCrosse 2,902 7,066 -58.9   2,902 7,066 -58.9   Regal 3,408 3,708 -8.1   3,408 3,708 -8.1   Buick Total 51,867 56,804 -8.7   51,867 56,804 -8.7   ATS 522 3,962 -86.8   522 3,962 -86.8   CT6 2,188 2,467 -11.3   2,188 2,467 -11.3   CTS 2,428 2,442 -0.6   2,428 2,442 -0.6   Escalade 6,819 8,111 -15.9   6,819 8,111 -15.9   XT4 7,026 0 ***.*   7,026 0 ***.*   XT5 13,278 14,845 -10.6   13,278 14,845 -10.6   XTS 3,734 4,898 -23.8   3,734 4,898 -23.8   Cadillac Total 35,995 36,727 -2.0   35,995 36,727 -2.0   Blazer 3,023 0 ***.*   3,023 0 ***.*   Bolt EV 4,316 4,375 -1.3   4,316 4,375 -1.3   Camaro 12,083 11,792 2.5   12,083 11,792 2.5   Colorado 33,494 28,859 16.1   33,494 28,859 16.1   Corvette 3,943 4,457 -11.5   3,943 4,457 -11.5   Cruze 23,311 39,855 -41.5   23,311 39,855 -41.5   Equinox 88,500 82,398 7.4   88,500 82,398 7.4   Express 17,215 19,774 -12.9   17,215 19,774 -12.9   Impala 13,259 14,067 -5.7   13,259 14,067 -5.7   LCF 559 530 5.5   559 530 5.5   Malibu 34,197 34,150 0.1   34,197 34,150 0.1   Silverado 114,313 135,545 -15.7   114,313 135,545 -15.7   Sonic 4,460 5,983 -25.5   4,460 5,983 -25.5   Spark 6,423 6,945 -7.5   6,423 6,945 -7.5   Suburban 11,029 14,725 -25.1   11,029 14,725 -25.1   Tahoe 20,853 23,643 -11.8   20,853 23,643 -11.8   Traverse 34,223 38,198 -10.4   34,223 38,198 -10.4   Trax 24,580 20,482 20.0   24,580 20,482 20.0   Volt 2,520 3,478 -27.5   2,520 3,478 -27.5   Chevrolet Total 452,401 490,919 -7.8   452,401 490,919 -7.8   Acadia 31,200 29,900 4.3   31,200 29,900 4.3   Canyon 6,954 7,213 -3.6   6,954 7,213 -3.6   Savana 6,566 4,797 36.9   6,566 4,797 36.9   Sierra 40,546 41,468 -2.2   40,546 41,468 -2.2   Terrain 25,364 32,964 -23.1   25,364 32,964 -23.1   Yukon 14,947 15,002 -0.4   14,947 15,002 -0.4   GMC Total 125,577 131,344 -4.4   125,577 131,344 -4.4   GM Vehicle Total* 665,840 715,794 -7.0   665,840 715,794 -7.0                     76 selling days for the QUARTER 1 this year and 77 for same QUARTER last year.
