How does the
TCC Rating work?
The TCC Rating is a clear numeric rating value based on a 10-point scale that reflects the overall opinion of our automotive experts on any vehicle and rolls up ratings we give each vehicle across sub-categories you care about like performance, safety, styling and more.

Our rating also has simple color-coded “Stop” (red), “Caution” (orange),
or “Go” (green) messages along with the numerical score so you can easily understand where we stand at a glance.

Our automotive experts then also collect and show you what other websites say about these different aspects of any vehicle. We do this leg work for you to simplify your research process.

TheCarConnection.com's editors have driven both the GMC Sierra 1500 and the Sierra Hybrid, and have written this road test summary from firsthand driving impressions. Editors have compared the Sierra with other full-size trucks, and have compiled a companion full review from other Web reviews and opinions, to give you a comprehensive look at the latest GMC full-size pickup.

The GMC Sierra 1500 was completely redesigned in 2007, alongside the nearly identical Chevrolet Silverado, and because of its conservative but tasteful style, it still looks fresh today. It's a little plain, though-more assertive than the Chevy truck but not as arrogantly square as the Ford F-150, nor as butch and bold as the Dodge Ram. The Sierra's wide, tall grille is its hallmark, with big GMC lettering inside; the boxy flares around its fenders are subtle reminders that this is the same brand that sells the extreme-looking 2010 Terrain crossover. Inside the Sierra's cabin, some models have a simple, upright design with larger controls and door handles-better suited for work duty-while pricey versions have an interior that would fit in a luxury sedan. The upgraded instrument panel has a smoother, lower design, as well as surfaces and materials that come together nicely. The 2010 GMC Sierra Hybrid is more of the same; unless it's fitted with the optional hybrid decal package and the hybrid LCD readouts, observers will likely not notice it as different from a standard Sierra pickup. The 2010 model year brings only minor changes to the Sierra, including revised interior door panels.

With such a broad range of refined and responsive powertrains, there's an engine choice for any buyer. The lineup starts with the base 195-horsepower, 4.3-liter V-6 installed in workhorse models. A flexible-fuel, 302-hp 4.8-liter V-8 is the first optional engine. There's also a flex-fuel 5.3-liter V-8 with 315 hp and cylinder deactivation for improved fuel economy, which is standard in XFE models and available in other versions. The most expensive Sierra pickups get a 6.2-liter, 403-hp, flex-fuel V-8 that also shows up in the swank Cadillac Escalade. The 5.3-liter is TheCarConnection.com editors' pick, as it has plenty of power for most needs without much lower fuel economy than the base V-6. The base V-6 and base V-8 are teamed with a four-speed automatic; all other versions have a six-speed automatic that shifts very smoothly, helps achieve better fuel economy, and cuts down on noise. The Sierra gets up to 15/22 mpg in the XFE edition, falling to only 12/19 mpg in loaded versions.
