The Acadia midsize SUV gets a major update this year as new, more modern competitors hit the market. It features a redesigned grille and taillights, an updated infotainment system, a new head-up display and extra safety content. There’s also a new 2.0-litre turbo engine producing 230 horsepower and 258 pound-feet of torque, a new nine-speed automatic transmission, a more refined suspension and a rugged-looking off-road model called AT4. This one gets a standard 310-horsepower V6.
