For the moment, the 2021 GMC Acadia is offered in five different trim levels, including the entry entry-level SL, the SLE, the SLT, the off-road-oriented AT4, and the range-topping Denali. However, GMC will drop the entry-level SL with the introduction of the upcoming 2022 GMC Acadia.
General Motors currently offers the 2021 GMC Acadia SL trim exclusively with front-wheel drive and the naturally aspirated 2.5L I4 LCV gasoline engine, which produces 193 horsepower at 6,300 rpm and 188 pound-feet of torque, and mates to a nine-speed automatic transmission. What’s more, the Acadia’s SL trim is only available in Summit White exterior paint with a Jet Black interior, with no significant options to speak of.
To be specific, the GMC Acadia SL doesn’t offer a power driver’s seat, active safety features, SiriusXM radio, remote engine start, six-passenger seating option, heated front seats, power liftgate, or roof rails. Each of these items is available on the Acadia SLE or SLT and up.
Looking ahead, the debut of 2022 GMC Acadia and deletion of the SL trim will make the SLE the most affordable trim level in the Acadia lineup going forward.
As GM Authority covered previously, the 2022 GMC Acadia will ditch the naturally aspirated 2.5L LCV gasoline engine outright, making the turbocharged 2.0L I4 LSY the standard engine for lower trim levels. The naturally aspirated 3.6L V6 LGX will also be carried over, available higher in the trim level structure.
To note, the turbocharged 2.0L I4 LSY gasoline engine is now rated at 228 horsepower at 5,000 rpm and 258 pound-feet of torque from 1,500 to 4,000 rpm, while the naturally aspirated 3.6L V6 LGX is rated at 310 horsepower at 6,600 rpm and 271 pound-feet of torque at 5,000 rpm. Both engines mate to the GM nine-speed automatic transmission.
The current 2021 GMC Acadia follows the nameplate’s mid-cycle refresh, which debuted for the 2020 model year. The Acadia rides on the regular wheelbase variant of the GM C1 vehicle platform, and is produced at the GM Spring Hill facility in Tennessee.
