2007 GMC Sierra Review

Combines a refined interior and smooth, comfortable ride with strong capabilities.

Reviewed by Automotive on

Overview

Building on the traditional strengths of the GMC Sierra, the 2007 models was redesigned to include many of the aspects that drivers want. This workhorse is still being sold as a classic full-size truck, but the extreme makeover will give shoppers more high-quality materials, more robust frame, and an optional automatic six-speed transmission.

When first glancing inside of the 2007 GMC Sierra, the interior quality is evident. Using high-quality plastics and other luxury features, the interior could be compared to the Cadillac ambience. The Denali and SLT interior has elegant accents of metallic and wood finishes, which gives a very lustrous feel and look. The ride is comfortable and smooth as well. The transmission choices are good with the automatic six-speed being a superb option.

The current rack-and-pinion setup of the steering has improved handling, and the safety features were updated to include most of them as standard equipment. Overall, the 2007 GMC Sierra is slated to become one of the top runners for well-built, versatile trucks of the segment.

What's New

From the roof to the tires, the GMC Sierra is completely new. Main improvements to trim interior, safety features, build quality, and tow capabilities make it a favorite of the full-scale pickups.

Exterior

The 2007 GMC Sierra has three body styles for the full-size pickup, which are the standard cab, the crew cab, and the extended cab. The standard cab comes with the long bed, short bed, or standard size, whereas the crew cabs come with short bed styles only. The short bed is easier to maneuver for parking and getting through traffic. The regular cab models come in the Work Truck style or SLE, and the crew and extended cabs are available with those two trims or the upper SLT level. The Denali offers just the crew cab form. The exterior features of the Sierra are 18- or 20-inch wheels, depending on the model.

Interior

The Work Truck comes with most of the basics that include trip computer, vinyl seats, air-conditioning, OnStar telematics, tilt steering wheel, and front bench seat with the 40/20/40-split. Other standard features that come on the remaining models include cruise control, cloth seating, automatic climate control, keyless entry, and full power accessories. The models with the SLE2 trim level will add dual-zone functioning for the automatic climate control, audio controls that are mounted on the steering wheel, and front bucket seats. Further additions to the list is the keyless start/entry, heated front seats, leather seating, and six-disc CD player and changer on the SLT models.

The upper-level Denali includes a navigation system, DVD rear-seat entertainment system, remote start, and satellite radio, along with many optional packages for sprucing up the exterior of the Sierra Denali model.

Performance & Handling

There are several different engines concerning the 2007 GMC Sierra. Beginning with the work truck, the 4.3-liter V-6 is used to provide 195 horsepower and 260 lb-ft of torque. Then the SLE1 model trucks get the 4.8-liter V-8, which generates 295 hp with 305 lb-ft torque, except for the long-box version of the model. Powering the SLE2 Sierra model is the 5.3-liter V-8 that packs a good amount of horses at 315 and 338 lb-ft torque. Lastly, the Sierra Denali model contains the 6.2-liter V-8 that makes a whopping 403 horses with 417 lb-ft torque, and optionally can be equipped with the Vortex Max. This is the 6.0-liter V-8, which can generate 367 hp with 375 lb-ft torque to compete with the others in the SUV segment.

With the Max optional trailer package and properly equipped, the Sierra can tow up to 10,500 pounds, which is a great capacity for an SUV to achieve. The automatic four-speed transmission is standard, and the automatic six-speed can be chosen as an option. Also the choice of four-wheel or two-wheel drive exists for all models. The exception is the Denali, and it comes with the automatic six-speed as standard equipment. All models besides the Denali model come with Autotrac feature that allows an automatic gear shift whenever wheel slippage is felt and detected. The Denali AWD version does not need intervention with the full-time system in place.

Safety

Anti-lock brakes come standard on each GMC Sierra with an optional all-disc version. Stability control with rollover mitigation comes standard on the crew cab but optional on the extended cab. An optional feature across the line is the rear parking assist. The Sierra Denali has all preceding features standard with OnStar and disc brakes.
