Back in July, we reported that the GMC Acadia AT4 ships with 17-inch wheels (RPO code Q7D) and chunky all-terrain tires as standard, but that the rugged midsize crossover also offers a set of optional 20-inch wheels (SSZ) wrapped in all-season tires, as a $900 option. And now, GM Authority has learned from those familiar with product plans that the 20-inch wheels are no longer available for the Acadia AT4.
The change means that the black, six-spoke 17-inch wheels are the only wheel option for the 2021 Acadia AT4.
|2021 Acadia AT4 – Standard||17-inch Gloss Black aluminum (Q7D)||All-Terrain (5GV)||Standard|
|2021 Acadia AT4 – Optional||20-inch Machined Aluminum with Dark Accents (SSZ)||All-Season (QNU)||Optional*|
- * No longer available
The reason for the sudden discontinuation of the optional 20-inch SSZ wheels is uncertain. Also unclear is whether the Acadia AT4 will once more be offered with the larger wheels at some time in the future.
Introduced for the 2017 model year, the second-generation GMC Acadia rides on the regular wheelbase variant of the GM C1 platform. Engine options include the atmospheric 2.5L I4 LCV, the turbocharged 2.0L I4 LSY, and the atmospheric 3.6L V6 LGX. A nine-speed automatic transmission is standard across the line as of the 2020 model year refresh. Both AWD and FWD are offered.
The Acadia AT4 slots above the SL, SLE and SLT trim levels, but below the range-topping Acadia Denali. The AT4 features the 3.6L V6 LGX engine and AWD as standard. The base MSRP for the 2021 Acadia AT4 is $42,295, including the $1,195 destination freight charge.
Production of the second-gen Acadia takes place at the GM Spring Hill plant in Tennessee.
