There’s even a hybrid model. With so many configurations, most shoppers can create their ideal Sierra.
The Sierra impresses with good fuel economy, powerful engine options and comfortable seats. The GMC Sierra also doesn’t have many interior cubbies, which makes storing small items difficult.
The 2011 GMC Sierra 1500 shares its basic design and engineering with the Chevrolet Silverado 1500 but dresses in more image-conscious trim. Should you wait for the 2011 GMC Sierra 1500 or buy the 2010 GMC Sierra 1500? Buy the 2010 Sierra.
Styling:
No styling changes of note are expected for the 2011 GMC Sierra 1500. Additional GMC insignia inside and out, cabin trim details, and GMC-specific model designations round out the differences. The 2011 Sierra will again share with Silverado a three-cab roster consisting of a two-door regular-cab, an extended cab with small, rear-hinged back doors, and a crew cab with four conventional doors. Crew cabs use the 5-8 bed. Expect the 2011 GMC Sierra to repeat a model lineup ascending from basic Work Truck (WT), through SL and SLE models to the posh SLT. Along with the mileage-tweaked XFE (Xtra Fuel Economy) model, these Sierra trim levels mirror the Silverado model march.
Mechanical:
No significant mechanical changes are on tap for the 2011 GMC Sierra 1500. The 4WD systems include low-range gearing. The Sierra Hybrid combines a 6.0-liter V-8 with electric motors imbedded in the transmission casing. The Sierra Hybrid can reach 30 mph on electricity alone.
Features:
Don’t expect major changes in features for the 2011 GMC Sierra 1500. GMC could trump Ford’s deployable bed-side steps without much Sierra re-engineering. An integrated trailer-brake controller is already available on all Sierra models.
Performance
The 2011 GMC Sierra 1500 regular cab comes with three engine choices. Fuel economy for a 4WD and a 4-speed automatic transmission pairing is estimated at 14/18 MPG.
The Sierra 1500 that is most likely to win the Sierra Club's favor, however, runs on the Vortec 5.3L Variable Valve Timing V8 FlexFuel engine with Active Fuel Management. Horsepower and torque rise somewhat from the 4.8L's ratings to 315 HP and 335 foot-pounds.
The beefiest engine, also with flex fuel capabilities, is the Vortec 6.2L Variable Valve Timing V8 SFI (Sinquential Fuel Injection).
Interior Features
The base work model offers basic features, such as air conditioning, OnStar, and a CD player with satellite radio, mp3 compatibility, and a satellite radio. Upgraded trims offers features such as cruise control, leather upholstery, and upgraded audio systems.
