The 2011 GMC Acadia now is available in the premium Denali trim level, which features unique styling elements and a plusher cabin. Additionally, the OnStar telematics system now includes a standard six-month subscription to Directions and Connections
Only one engine and transmission combination available for the 2011 GMC Acadia – a 3.6-liter V6 mated to a six-speed automatic with manual shift controls. In LS and LT – that have a single exhaust system – the V6 produces 281 horsepower and 266 lb-ft of torque. In the unique LTZ V6 output jumps to 288 hp and 270 lb-ft thanks to a dual-outlet exhaust.
EPA fuel economy estimates for the front-wheel-drive Acadia are 17 mpg city/24 mpg highway and 19 mpg combined. All-wheel-drive Acadia models are very close at 16/23/19 mpg. Properly equipped, the Acadia can tow up to 5,200 pounds.
The plush Denali trim level adds unique body treatment (including grille, front/rear fascias, side moldings and wheel flares), 20-inch chrome wheels with black chrome accents, xenon headlights, additional sound insulation, illuminated sill plates, the "SkyScape" power front/fixed rear dual sunroofs, a head-up display, perforated leather upholstery, heated/ventilated front seats and a leather/wood steering wheel.
Acadia features standard power-assisted rack-and-pinion steering, with variable-effort steering available. The suspension and steering system meet the road via standard 18-inch wheels and tires, with 19-inch wheels available. Four-wheel disc brakes with ABS are standard. The Acadia also offers the following standard features that enhance ride and handling, as well as safety:
* StabiliTrak electronic stability control system with rollover mitigation technology
* Traction control system
* Tire pressure monitoring system
* Four-wheel disc brakes with ABS.
Antilock disc brakes, traction and stability control, front seat side-impact airbags and side curtain airbags for all three rows are all standard on the 2011 GMC Acadia, as is one year of GM's OnStar service, including turn-by-turn navigation and hands-free phone connectivity. In Edmunds brake testing, an Acadia came to a stop in 135 feet -- the Flex and CX-9 perform better.
Along with comfort and ease of entry, Acadia’s interior offers generous cargo room, including 115.9 cu. ft. (1,382 L) when the second- and third-row seats are folded flat and the cargo management removed. Additional storage is also available in a covered rear cargo convenience center behind the third row that allows items to be stored out of sight beneath the rear cargo floor.
