Efficient powertrain
The Acadia is powered by GM's 3.6L V-6 with variable valve timing (VVT), which is designed for good fuel economy, low emissions and exceptional smoothness. Paired to this engine is a new fuel-saving Hydra-Matic 6T75 six-speed automatic transmission. Acadia can tow up to 4,500 pounds (2,041 kg), when properly equipped, and comes in both front-wheel drive and all-wheel drive models.
