GMC wants to place the Acadia AT4, the latest member of its AT4 submarket, as a prize but not an all-out luxury crossover that can handle itself in a more robust situation. It will be powered by the well-known 3.6-liter V6 with 310 hp and 271 lb-ft of torque paired to a twin-clutch transmission power to all four wheels. Seventeen inch wheels are standard, while 20-inch wheels are optional.
Apart from the new exterior styling and AT4 trim, the other major highlight is the introduction of a brand new dual-scroll turbocharged 2.0-liter four-cylinder with an estimated 230 hp and 258 lb-ft. It will be standard on SLT and Denali models, while base-2.5-liter inline four will transfer from last year unchanged. A new 9-speed automatic transmission will be standard on all 2020 Acadia trims, and it is controlled by GMC's Electronic Precision Shift, a system that replaces the pin and pushbuttons and pulls triggers.
