The 2017 GMC Acadia is a midsize crossover SUV, redesigned for its second generation. It is powered by a 2.5-litre four-cylinder that produces 193 horsepower or an optional 3.6-litre V6 with 310 horsepower, both paired to a six-speed automatic transmission with available FWD or AWD. Available trims include the SL, SLE, SLT, and top-end Denali, each progressively adding higher-end materials and features. Noteworthy tech and safety features include an infotainment system with a 7-inch touchscreen (upgradable to an 8-inch), Apple CarPlay, Android Auto, onboard Wi-Fi, adaptive cruise control, and forward collision warning with automatic braking. Compared to its predecessor, the 2017 model is noticeably smaller and lighter, improving maneuverability and fuel efficiency.
