2010 GMC Sierra 1500 Extended Cab Review

By

Long regarded as the twin of the Chevrolet Silverado, the 2010 GMC Sierra 1500 offers more differentiation from its General Motors stable-mate in looks, while sharing the same basic architecture and engine choices. Exclusive to the GMC Sierra line, though, is the Denali trim level that brings with it a variety of power and luxury features. Looking to extend their leadership in the pickup truck segment, GM engineers and designers have created a new breed of pickup, one offering an improved chassis, more precise steering and not one but two quieter, more upscale interiors. The Sierra also delivers segment-leading fuel economy thanks to the new line of Active Fuel Management-equipped V8 engines and the introduction of the Two-Mode hybrid model.

You'll Like This Car If...

If you need the hauling and towing capabilities of a full-size pickup truck, you can have them while at the same time contributing to the environment via a V8-engine lineup that offers Active Fuel Management technology and Flex-Fuel E85 capability.

You May Not Like This Car If...

If you have trouble making up your mind, you might be boggled by the number of trim levels, cab sizes, bed lengths and even instrument panels. Rising fuel costs might also have you looking to a smaller, V6 powered truck.

What's New for 2010

The 4.8-liter, 5.3-liter and 6.2-liter V8 engines are now E85 Flex-Fuel compatible; the 4.8- and 5.3-liter engines also gain variable valve timing. New standard features on all 1500 models include side-curtain and front seat-mounted side-impact airbags as well as StabiliTrak stability control. New available features include a USB port on all but the base radio, a six-speed automatic transmission on Regular and Extended Cab models with the 5.3-liter engine and greater availability of the rear backup camera option.

Driving the Sierra 1500 Extended Cab

Driving Impressions Sufficient power and surprising ride comfort are two hallmarks of the 2010 GMC Sierra 1500. Riding on a fully-boxed frame for more chassis stiffness, with coil-over-shock front suspension and rack-and-pinion...

steering, GMC's big pickup truck is surprisingly nimble and easy to maneuver. Our lengthy test drive took us over rough, washboard gravel roads, yet the Sierra's cabin retained library-like calm and quiet. We found it hard to choose between the "pure pickup" interior and the "luxury-inspired" interior, because both were handsome and functional. While the available 4.3-liter V6 is no doubt adequate, the Sierra can also be equipped with a variety of V8 engines, most with 5.3-liter displacement, while the Denali and SLT offer a 6.2-liter V8. While we expect the 4.3-liter V6 and 4.8-liter V8 to be more than adequate in work truck applications, we recommend the 5.3-liter V8 engines, some with cast iron blocks and some with aluminum, but all with Active Fuel Management and variable valve timing. And for those who want more power (or towing capacity) the 6.2-liter is tops in its class, offering significantly more power and torque (pulling force) with very little penalty in fuel economy.

OnStar 8.0
The latest OnStar system includes available Bluetooth connectivity and a Turn-by-turn navigation with Destination Download on models equipped with DVD-based navigation.

Active Fuel Management
The Active Fuel Management system available on the 5.3-liter V8s cuts the operation of four cylinders when they are unneeded and enhances fuel economy.

Interior

The 2010 GMC Sierra 1500 benefits from GM's ongoing reworking of both full-size pickups and full-size SUVs, and among the benefits are two distinct interiors. The work truck and SLE trim levels feature the "pure pickup" interior that features larger controls – designed to accommodate gloved hands – and a double glovebox. The SLT trim level features the same "luxury-inspired" interior also used in GMC's SLT-trim Yukon and Yukon XL full-size sport utilities. Both attractive instrument panels are mounted low and far forward for an increased feeling of spaciousness. The same can be said of the back-seat area in the crew cab models, which offers ample room and comfort. Its elevated stadium-style rear seat has a 60/40-split design and folding center armrest, and it can be easily folded up with one hand to provide an uninterrupted load floor.

Exterior

While the 2010 GMC Sierra 1500 does share the "strong, silent-type" handsomeness of the Silverado, it also offers a distinct front end, front and rear fenders and hood. An upscale look is highlighted by narrow gaps between body panels, enabled by the new version's significantly stiffer frame. The grille with prominent GMC logo is complemented by large "jeweled-appearance" headlights. The pickup box is taller than in previous generation Sierras and, at the same time, better integrated. The stamped-in rear fender flares are designed to give the truck a muscular look. Standard wheels are 17 inches in diameter, while 22-inch wheels are also available. Easy entry into the rear seat/storage area of extended-cab models is accommodated by new rear access doors that open 170 degrees. Power-operated rear-side windows lower completely into the access doors.

Notable Equipment
Standard Equipment

The 2010 GMC Sierra 1500 is offered in five trim levels from basic to sinfully luxurious. The base model is the WT (work truck), and then, ascending the food chain, the SLE, SLT and Denali. In fact, the Sierra Denali is virtually a distinct model unto itself and includes as standard a 6.2-liter all-aluminum V8 engine and six-speed automatic transmission. Cloth seats are standard on WT and SLE models, and leather seating is available on SLE models. SLT models include standard leather seats, the "luxury" instrument panel, 12-way power-adjustable driver's seat, six-disc audio system with Bose speakers, Bluetooth phone connectivity, and heated windshield washer system. The crew-cab SLT version is even more luxurious with rain-sensing windshield wipers and a rear-seat audio system. Even the base trim level includes a four-speed automatic transmission, tire pressure monitoring system, power rack-and-pinion steering, anti-lock brakes (ABS), air conditioning, tinted glass, full instrumentation, XM Satellite radio, side impact and head curtain airbags and two auxiliary power outlets. StabiliTrak stability control is standard on all 1500 models.

Optional Equipment

The multiplicity of trim levels should allow you to fine-tune your Sierra to the equipment level you want, but options abound as well. Convenience features offered on SLE and SLT models include touch-screen navigation/sound system, power-operated moonroof, rear backup camera and a power-sliding rear window. The Denali trim offers heated and cooled front seats. Sierra offers five distinct suspension systems, each tailored to suit specific driving requirements. They include Z83 for a solid, smooth ride, Z85 for enhanced handling and trailer towing, Z71 for enhanced off-road capability, Z60 for street performance with 20-inch wheels and NHT for maximum towing capacity. A choice of two- and four-wheel-drive models, various cabs and bed lengths and a variety of axle ratios are also offered.

Under the Hood

While we expect the 4.3-liter V6 and 4.8-liter V8 to be more than adequate in work truck applications, we recommend the 5.3-liter V8 engines, some with cast iron blocks and some with aluminum but all with Active Fuel Management and variable valve timing. And for those who want more power (or towing capacity) the 6.2-liter V8 available only on the Denali trims is tops in its class, offering significantly more power and torque (pulling force) with very little penalty in fuel economy.

"Best driving truck I have ever owned. Large fuel tank (36 gal)and excellent fuel mileage (20 mpg/hwy) are also a great improvement over previous trucks. Navigation system "learns" routes not in the database. Quiet interior and engine make it pleasant to drive, smooth ride (even on oil well lease roads)."

"This is the best truck I have ever owned. I have just driven it from Massachusetts to Georgia and it was the best ride in a truck I ever have done. And that was towing a 12 foot landscape trailer with a load on! Powerful 5.3, quiet cab, pulls with ease, comfortable seats and interior setup, looks good and even gets decent millage for a full size truck. I'm happy."

"has done a good job for me for 6 years, used mostly for plowing snow and highway mileage, had some issues with front end as far as wear and tear which is expected, need to put a cover on console so when you bring a 3rd person into the cab, you don't have to empty console when flipping up. has served me well."
