Available with FWD or AWD, this vehicle is powered by a 3.6L V6 that produces 288 hp and 270 lb-ft of torque. As with the Traverse and Enclave, the Acadia only comes with one type of transmission, a 6-speed automatic. The AWD system is quite efficient. This crossover can accommodate up to eight passengers.
