Acadia’s body-frame integral structure enables lower entry/exit height for passengers. Despite the vehicle’s SUV-like front-end height, the front door step-in height is only 18.9 inches (480 mm); the rear door step-in height is 19.8 inches (503 mm). Entry to the second- and third-row seats is easy with very wide rear doors and GM’s exclusive Smart Slide second-row seat feature. All models are powered by a 3.6L V-6 VVT engine that uses gasoline direct injection technology to optimize performance and fuel economy. The engine is paired with Acadia’s fuel-saving six-speed automatic transmission to help give FWD models an EPA-estimated 24 mpg on the highway. The Acadia also is capable of towing up to 5,200 pounds (2364 kg), when properly equipped. Acadia’s interior exudes refinement and attention to detail, with many thoughtful features designed into a finely crafted environment. A car-like “low and away” instrument panel enhances the feeling of openness in the front-row seats and provides a commanding outward view. The instrument panel and other interior elements feature high-quality, low-gloss materials and tight gap tolerances. Features that reinforce Acadia’s refinement and complement passenger comfort include: Heated outside mirrors that quickly de-fog or de-ice for improved visibility A power liftgate that opens and closes with the key fob, a button just inside the liftgate or from the front seat, with a switch in the center console Extended-range remote vehicle start SkyScape dual sunroof, featuring a larger, power-operated tilt-and-slide sunroof and rear skylight, which combine to provide an airy, open driving experience Head-up display that projects instrument readouts and other features onto the windshield for easy, eyes-on-the-road reference A DVD entertainment system that offers rear-seat passengers a multimedia experience with a flip-down DVD screen, infrared headphones and individual controls A Bose 5.1 Surround Sound audio system with optimally located speakers that provide big, clear and crisp sound throughout the vehicle A DVD touch-screen navigation system that provides locations, directions and driving instructions via a large, easy-to-view LCD screen Heated/cooled seats. XM Satellite Radio is standard on all models and is available with NavTraffic real-time traffic advising.
