The 2010 GMC Sierra 1500 with the 5.3-liter V8 receives tweaks that yield incrementally better fuel economy, including a standard six-speed transmission and variable valve timing. The 6.2-liter V8 also gets a standard six-speed. The 6.0-liter V8 has been dropped, but all remaining V8s can now run on E85 as well as gasoline. Side curtain airbags, seat-mounted side airbags and stability control are standard on all models, and USB connectivity is optional on SLE and SLT (standard on Denali).
The 2010 GMC Sierra 1500 is a half-ton full-size pickup that's available in three body styles: standard cab, extended cab and crew cab. Standard cabs can be had with a standard bed (6-foot, 6-inch) or long bed (8-foot). Extended cabs can have a short (5-foot, 8-inch), standard or long bed. In the interest of maneuverability, crew cabs come only with the short bed.
There are four different engines available for the 2010 GMC Sierra 1500. Work trucks have a 4.3-liter V6 (195 horsepower, 260 pound-feet of torque) as standard. This can be upgraded to a 4.8-liter V8 (295 hp, 305 lb-ft) or a 5.3-liter V8 (315 hp, 338 lb-ft). The SLE trims will have one of the two V8s as standard, depending on style, while the SLT has the 5.3-liter engine as standard.
Available on select models is a 6.2-liter V8 (403 hp and 417 lb-ft). The 6.2 comes standard on the Denali. A six-speed automatic transmission is standard on the two big V8s, while the 4.8-liter V8 and the V6 come only with a four-speed automatic. In 0-60-mph testing, we clocked the related Silverado with the 6.2-liter V8 in a very quick 6.6 seconds. Properly equipped, a Sierra 1500 can tow up to 10,600 pounds.
The Sierra's base interior is a little dull relative to the competition. However, the Sierra SLT and Denali feature a unique upscale dash and door panel treatment with a full center console and attractive wood grain and metallic accents, although you'll pay a stiff entry price for this privilege. The rear seat in crew cab models is quite comfortable, and the seat cushions can be folded upward for a nearly flat load floor. Interior storage is adequate, but some might take issue with the smallish cupholders and the haphazard organization of the center console box.
The 2010 GMC Sierra 1500 is part of the new breed of big trucks that are actually pleasant to drive. The steering is light but reasonably precise, and the truck's comfortable seats and smooth, quiet ride make long road trips enjoyable. However, the Sierra's turning circle is a little larger than that of most other trucks. Acceleration is sluggish with the base V6 but just fine with even the modest 4.8-liter V8. The 5.3-liter V8 feels brawny, and the 6.2-liter V8 turns the Sierra into a veritable muscle truck. We much prefer the six-speed automatic that comes standard with the two bigger V8s; the four-speed feels past its prime.
