Chevy Trailblazer Gas Mileage: Real-World Fuel Efficiency in 2025

The 2025 Chevy Trailblazer has quickly become a top choice for adventurers and daily commuters alike. Known for its rugged design and modern tech, fuel economy remains a key concern for many buyers. This guide breaks down the Chevy Trailblazer’s gas mileage performance using 2025 data, helping you understand what to expect across trims and driving conditions.

What Drives the Trailblazer’s Fuel Economy?

The Chevy Trailblazer’s gas mileage varies based on engine type, transmission, and trim level. The base 2.5L turbocharged inline-4 engine in the base model delivers strong efficiency, while the 3.6L V6 and hybrid-ready options offer more power with a nuanced impact on fuel consumption. According to 2025 EPA estimates, the base 2.5L model achieves an estimated 22 mpg combined, with the 3.6L V6 offering around 18 mpg in city driving and 26 mpg on the highway.

• Why does engine displacement matter? Larger engines typically consume more fuel, but modern turbocharging and direct injection improve efficiency across many models.
• How does driving style affect mileage? Aggressive acceleration and high speeds reduce fuel economy significantly, especially on highways.

Real-World Mileage by Trim and Use Case

Two main variants dominate the Trailblazer lineup: the 2.5L and the 3.6L. Owners often report slightly better efficiency with the smaller engine, particularly in city traffic and mixed driving. For example, a full-size Trailblazer with the 3.6L V6 averages 16–20 mpg city and 24–27 mpg highway. However, the 3.6L’s torque and smoother power delivery make it ideal for off-road excursions and towing light loads without sacrificing too much fuel.

• Compact Trailblazer (2.5L): 22 mpg combined—excellent for daily commutes.
• Full-Size Trailblazer (3.6L): 18 mpg city, 26 mpg highway—balanced power and economy.

Trim Features Impacting Fuel Use

Beyond engine size, features like AWD, premium infotainment, and comfort packages influence fuel consumption. The Trailblazer’s standard AWD system, while enhancing traction, adds weight and mechanical resistance, lowering highway efficiency by approximately 2–4 mpg compared to AWD-off modes in city driving. Upgrade to a comfort or tech-focused trim with minimal penalty—modern lightweight materials and turbocharged engines help keep fuel burn in check.

• AWD boosts reliability but may reduce mpg by up to 5% on dry roads.
• Upgraded infotainment and seats add weight, slightly impacting fuel economy.

Maximizing Gas Mileage: Pro Tips from Experts

To stretch every gallon, follow these actionable steps: maintain steady speeds, avoid rapid acceleration, use cruise control on highways, and keep tire pressure within recommended levels. Regular maintenance—such as oil changes and air filter replacements—ensures the engine runs efficiently. With proper care, the 2025 Trailblazer can exceed 20 mpg combined in real-world use, even with the more powerful engine.
