What engines do Trailblazers have?
Today, Trailblazers are powered by two turbocharged inline-3 engines: a 1.2-liter and a 1.3-liter. The exact options and transmissions vary by market and trim.
Current Trailblazer engines
In the United States and most markets, Chevrolet offers two turbocharged 3-cylinder engines for the Trailblazer, each paired with a different transmission to balance performance and efficiency.
- 1.2-liter turbocharged inline-3 engine: about 137 horsepower and around 162 lb-ft of torque, typically paired with a continuously variable transmission (CVT) for fuel efficiency.
- 1.3-liter turbocharged inline-3 engine: about 155 horsepower and roughly 174 lb-ft of torque, paired with a nine-speed automatic transmission for stronger acceleration and towing capability.
Both engines use modern turbocharging and direct injection to optimize power and efficiency, with trim- and market-specific tuning.
Past Trailblazer engines
Long before the current generation, Trailblazer models used a range of larger, naturally aspirated engines across generations, including inline-6 and V8 powertrains. The high-performance TrailBlazer SS showcased a big V8 in a family SUV.
- 4.2-liter inline-6 engine (early Trailblazer models): a robust six-cylinder option used in the early 2000s family SUVs.
- 5.3-liter V8 engine: available on higher trims for more power and towing capability.
- TrailBlazer SS (2006–2007): a 6.0-liter V8 delivering substantially higher horsepower for the performance variant.
These older engines reflect the Trailblazer's evolution from a practical mid-size SUV to the modern, efficiency-oriented crossover lineup.
Notes for buyers and market differences
Engine availability can vary by country, trim level, and model year. Some markets may offer different turbocharged options or discontinue certain engines as Chevrolet updates the lineup. Always check the exact powertrain for your region and model year when purchasing a Trailblazer.
Summary
In its current form, the Trailblazer offers two turbocharged inline-3 engines in many markets: a 1.2-liter variant and a 1.3-liter variant, with corresponding transmissions designed to balance performance and efficiency. Historically, the Trailblazer lineup included larger I6 and V8 engines, including a high-performance SS model. Prospective buyers should verify the engine and transmission in their specific market and model year.
