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 files for Z71 Trail Boss trademark

Try as they might to keep their plans a secret, automakers have their hands tipped through a variety of methods – be they through loose lips, spy shots or patent and trademark applications. That's how we know, in this instance, that General Motors is working on (or at least considering) an off-road machine wearing the name Z71 Trail Boss – the name which our compatriots at AutoGuide.com tell us that GM has registered for use on light-duty trucks. Now if that alphanumeric designator sounds familiar, it should. GM has long used it to designate the off-road packages on many of its body-on-frame trucks from Chevy and GMC. These days you can order a Z71 package on the Chevy Colorado, Silverado, Tahoe and Suburban and on the GMC Canyon, Sierra and Yukon. The package typically includes components like a beefed-up suspension bits, high-capacity air cleaner and underbody protection plates. The Trail Boss designator would seem to suggest something further reaching than a suspension package, though. Just what it would entail we don't know; minds immediately start running toward Chevy or GMC going after the Ford F-150 Raptor, but we'll likely be looking at something closer to the Trailhawk packages Jeep offers on the likes of the Renegade and Cherokee.

2021 GMC Yukon configurator now open for play-money builds

The 2021 GMC Yukon configurator is open for real and imaginary business. It's missing a number of important options, though, like the AT4 trim and the Premium Capability Package that installs the Air Ride Adaptive Suspension, so the configurator is best suited for practice runs at the moment. Playing our usual game, we started with a livery build in base SLT 2WD trim for an airport shuttle to compare to the livery 2021 Tahoe we built a few days ago. Same as with the Chevy, the GMC offers nine exterior colors. Opposite to the Chevy, the GMC makes you pay for every color except Summit White. Our Onyx Black selection added $195, five colors cost $495, Cayenne Red Tintcoat costs $695, and the super gonzo White Frost Tricoat runs $1,095. We plumped for the SLT Luxury package's driver assistance and convenience features like memory settings for the front passengers, powered seating for the second row, a split third row, the Rear Seat Media Package, and a console lockbox. What began as $59,095 after destination — $4,000 more than the 2021 Tahoe — ended at $64,445, just $2,165 more than our livery Tahoe because the Yukon packages more kit.   The amounts add up a lot quicker at the top end. Our regional rep with a fat bonus check started with a $72,295 Yukon Denali 4WD in the $495 Pearl Beige Metallic with a Teak and Light Shade interior. The $6,500 Denali Premium Package normally costs $500 more, and who can resist a sale? At about 9% of MSRP, it's not a negligible option, but it includes the $1,780 Advanced Technology Package, the $1,500 panoramic sunroof, and a set of 22-inch wheels that are normally $2,995. Since the bonus was big enough to replace the two-year-old jet skis in the garage, our rep added the $465 Max Trailering Package and that automatically appends the ProGrade Trailering features. Put in the Rear Seat Media Package to occupy the kids, locking armrest storage to protect stuff from the kids, and hook up a set of illuminated GMC badges for $535 to wow oncoming vehicles, and the total comes to $83,320. That's more than $10,000 in options without the least effort. However, there aren't any big-money options left to add except a $1,499 rooftop tent.     GM Authority wrote about the package combinations necessary to unlock the Air Ride Adaptive Suspension on the AT4 or Denali trims. Summed up, the check boxes add $3,410 to the price of an AT4, $3,755 to the price of a 2WD Denali, and $6,015 to the price of a 4WD Denali.
