The all-new 2021 GMC Yukon represents a complete overhaul of the popular full-size SUV range, delivering a completely redesigned exterior, an all-new interior, plus an overhauled platform with an independent rear suspension and a new electrical system. A particularly noteworthy addition to the lineup is the new rugged AT4 model, which expands GMC’s new AT4 sub-brand to the Yukon lineup to deliver a vehicle that focuses squarely on “rugged adventure,” according to GMC. Now that GM Authority has told you all about the three optional packages available for the Yukon Denali, we’re back to shed some light on the Premium Plus package for the Yukon AT4.
The AT4 Premium Plus package is the only substantial package offered on the 2021 Yukon AT4. It adds a considerable amount of features to the new rugged SUV to deliver what’s essentially a loaded vehicle:
- Max Trailering Package (NHT):
- ProGrade Trailering System (ZL6)
- Extra capacity cooling system (V03)
- Rear Media and Nav Package (WPB):
- Rear Seat Media System (UW9)
- 10.2-inch diagonal GMC Infotainment System with Navigation (IOT)
- Technology Package content (CWM):
- HD Surround Vision (UV2)
- Head-Up Display (UV6)
- Rear Pedestrian Alert (UKK)
- Premium Capability Package with Active Response 4WD (Z6E):
- Air Ride Adaptive suspension (F47)
- Electronic limited-slip differential (G96)
- Panoramic power sunroof (C3U)
- Power-retractable assist steps with perimeter lighting (B3L)
The GMC Yukon AT4 Premium Plus package is assigned RPO Code PEH and is priced at $9,145, GM Authority has learned. However, opting for it also enables a $1,000 package discount, resulting in a $8,145 total package cost. That’s on top of the $66,095 starting MSRP for the regular-length Yukon AT4 and $68,795 for the extended-length Yukon XL AT4.
So, if one opts for the AT4 Premium Plus package and no other options on the AT4, they’d be looking at a starting MSRP of $74,240 for the regular-length Yukon AT4 and $76,940 for the extended-length Yukon XL AT4.
Meanwhile, the standard Yukon AT4 is equipped with various unique features as standard that differentiate it from its SLE, SLT and Denali brethren, while also giving it more off-road prowess. Up front is a unique fascia that not only delivers an improved approach angle, but also delivers a more rugged appearance. The front fascia gets numerous dark accents and red recovery hooks, to boot.
The model rides on 20- by 9-inch, six-spoke machined aluminum wheels with Carbon Grey Metallic accents wrapped in 20-inch Goodyear all-terrain tires. The Air Ride Adaptive Suspension that’s part of the AT4 Premium Plus package allows the SUV to be raised by two inches, delivering an approach angle of almost 32 degrees.
Under the skin, the GMC Yukon AT4 gets a set of underbody skid plates and a two-speed transfer case. There’s also the Traction Select System with off-road mode as well as Hill Descent Control to help stability and traction in the rough stuff.
Inside, the 2021 GMC Yukon AT4 features a luxurious cabin, including leather-appointed seating with AT4 branding and stitching, plus a unique Jet Black color theme with Brandy accents unique to the AT4. Also standard are a heated steering wheel, heated and ventilated front seats and heated outboard seats for the second row.
The only engine on offer is the naturally aspirated 5.3L V8 L84 with Dynamic Fuel Management. The atmospheric gasoline motor is rated at a maximum of 355 horsepower and 383 pound-feet of torque. The gasoline is mated to GM’s new 10-speed automatic transmission. Four-wheel-drive is standard. The new turbodiesel 3.0L I6 LM2 turbo-diesel Duramax engine, which is optional on SLE, SLT and Denali, will not be offered on the AT4 due to complications with the unique front fascia.
Like other GMC AT4 models, the Yukon AT4 slots in the upper echelon of the Yukon model hierarchy, slotting above the SLE and SLT but below the Denali range-topper. Production of the 2021 GMC Yukon will kick off in late June at the GM Arlington Plant in Texas. However, the new Yukon AT4 will only go into production about three months thereafter as GM Authority exclusively reported last week.
