The TrailBlazer is a midsize five-door sport utility vehicle (SUV) from Chevrolet. It has a front-engine, rear-drive or four-wheel-drive layout. The TrailBlazer began production in 2001 for the 2002 model year, replacing the midsize four-door Chevrolet Blazer. The last model year was 2009 when it was replaced by the Chevrolet Traverse.
The TrailBlazer is known as a high-performance midsize SUVs with powerful engines, offering a quality ride in most driving conditions. The 2007 models have received a few upgrades over previous models from features to the powertrain and design.

The TrailBlazer has somewhat of a boxy profile for the 2007 model year, but with an aggressive front end and a number of quality details, it sports an all-around attractive look for a midsize SUV. The grille shares many features with the Tahoe, the next SUV size in Chevrolet’s SUV family. The TrailBlazer has a black diamond grille with the large Chevrolet logo in the center. It has a 113-inch wheelbase, measures 191.8 inches long, and has a ground clearance of 7.8 inches. Sixteen-inch wheels are standard and 17- and 18-inch wheels are available. The upgraded SS model rides an inch lower, but with the same clearance, adds a stiffer suspension, larger brakes, and has a bigger front stabilizer bar.
Two row seating is standard, and the backseats can fold down to fit extra cargo. When the back row and the passenger seat are folded down, around 80 cubic feet of cargo space is available. Standard models come with heavy plastic on the dashboard, a four-spoke steering wheel, and a large and very visible instrument panel. OnStar is standard in all vehicles. Options include an entertainment system in the backseat, satellite radio, adjustable pedals, and leather covers for the seats.
Performance & Handling
The 291-hp model produces 277 lb-ft of torque and, as the smallest engine in the lineup, still offers plenty of power. The large, 5.3-liter V-8 produces 302-hp at 330 lb-ft of torque and uses Active Fuel Management, which saves fuel by shutting four of the cylinders off when they’re not needed. However, the TrailBlazer still gets poor gas mileage within its class. The largest engine is the six-liter V-8 model. It is rated at 395-hp and produces 400 lb-ft of torque. This model offers very impressive performance within its class. Drivers have the option for rear- or four-wheel-drive, and fully-equipped models can tow up to 6700 pounds.
In addition to excellent performance, the TrailBlazer maintains a very quiet ride, except when pushed to the limits. There is little road noise, and overall, it is a comfortable ride, though with firmer seats, it may become uncomfortable on long trips. Handling is a bit disappointing, but the steering brings the driver close to the road.
Some of the safety features on the 2007 Chevrolet TrailBlazer include all-disc anti-lock brakes, electronic stability, optional side curtain airbags, and standard dual-stage front airbags.
