The 2011 GMC Acadia is part of the first generation of Acadia SUVs. Standard drive for this mid-size crossover is front-wheel, with an option for all-wheel drive. It is powered by a 288-hp 3.6L V6 engine paired with a six-speed automatic transmission. It stands out with its three trims: the SL, SLE, and SLT, each offering increasing levels of comfort and convenience. The base SL trim comes with keyless entry, cruise control, front and rear air-conditioning, and full power accessories. Higher trims add features like a back-up camera, power liftgate, and leather upholstery. For 2011, GMC introduced the Denali trim, offering a more luxurious package with polished wheels, a unique grille, upgraded leather in the interior, and enhanced sound insulation. All models feature a comprehensive suite of airbags, along with standard stability control, anti-lock brakes, and a tire pressure monitoring system. For infotainment, a six-speaker stereo with a CD player and satellite radio is available.
