The 2009 Chevrolet TrailBlazer is part of the vehicle's second generation. A mid-size SUV, the TrailBlazer features a standard rear-wheel drive, with all-wheel drive optional. Under the hood, drivers find a 4.2-liter inline-six engine that pushes out 285 horsepower or a 5.3-liter V8 that provides a brisk 300 horses. Both engines are paired with a four-speed automatic transmission. Available trims for this model year include the LS, LT, and range-topping SS, the latter of which adds a sports-tuned suspension and larger alloy wheels. Standard equipment includes dual-zone manual air conditioning, a CD player, and satellite radio. Safety features of the 2009 TrailBlazer include front side airbags and head curtain side-impact airbags. Unfortunately, this model year has been criticized for mediocre fuel economy and lack of refinement in the interior materials and design.
