The 2005 Chevrolet TrailBlazer is part of the vehicle's first and only generation, which started in 2002. It's a midsize SUV offered in three trims: LS, LT, and EXT, with the EXT model featuring an extended wheelbase and third-row seating. Under the hood, it houses a standard 4.2L inline-6 engine with 275 horsepower, while a 5.3L V8 making 300 horsepower is available for higher trims. A 4-speed automatic transmission sends power to either the rear wheels or all four wheels, depending on the selected drivetrain. Inside, one can find features like power windows and lock, CD player, and dual-zone air conditioning. On the safety front, ABS and a passenger-sensing system are standard, while side curtain airbags are optional.
