The 2020 GMC Acadia is getting a new grille and something being that grille that is notable, a 230-hp 2.0-liter turbocharged I4 that produces 258 lb-ft of torque. The all-aluminum engine, which is standard on the SLT and Denali trims, features what is called the GM “tripower valvetrain technology,” which means that it provides variable valve positioning as required, as in high valve lift for maximum power, low valve lift for a combo of power and efficiency, and, well, no valve lift for two of the cylinders during light load conditions because there is Active Fuel Management, a.k.a., cylinder deactivation.

2020 GMC Acadia AT4

The turbocharger has a twin-scroll design, which means that it is engineered to provide torque at low speeds, with the peak torque from the engine being available at from 1,500 to 4,000 rpm.

The 2020 Acadia also gets a nine-speed transmission, an improvement from the six-speed automatic that is in the 2019 models.

GMC will be offering the 2020 Acadia with a fourth trim, the AT4 (there is also the entry SLE).

The AT4 has a black-chrome accented grille, 17-inch wheels and all-terrain tires, providing the vehicle with more of an “off-road” appearance. (Think Denali as the upscale sub-brand and AT4 as the outdoor sub-brand.) The standard powertrain for the AT4 is a 310-hp, 3.6-liter V6. A twin-clutch all-wheel-drive system is standard for the vehicle.
