How many miles can a 2021 Chevy Trailblazer go?
A 2021 Trailblazer can typically travel roughly 350 to 420 miles on a full tank, depending on engine and drivetrain. The exact range depends on the vehicle’s fuel economy and the size of the fuel tank, with Chevrolet listing about a 12.7-gallon tank for many configurations.
Range by powertrain
Below are typical per-tank ranges based on EPA estimates and common driving conditions. Use these as planning guides rather than guarantees.
1.2L Turbo engine with Front-Wheel Drive (FWD)
In this configuration, efficiency is strong enough to yield a solid per-tank distance on a roughly 12.7-gallon tank.
- Estimated EPA combined mpg: roughly 28–31 mpg, depending on driving conditions.
- Estimated range on a full 12.7-gallon tank: about 350–380 miles.
For many buyers, this setup offers a favorable balance of performance and efficiency.
1.3L Turbo engine with Front-Wheel Drive (FWD)
The larger turbo can deliver similar or slightly better highway economy, translating to a comparable per-tank range.
- Estimated EPA combined mpg: roughly 29–30 mpg.
- Estimated range on a full 12.7-gallon tank: about 360–390 miles.
On longer highway trips, this configuration can stretch fuel stops further.
1.3L Turbo engine with All-Wheel Drive (AWD)
All-Wheel Drive adds traction but typically reduces fuel economy slightly, trimming the per-tank range a bit compared with FWD.
- Estimated EPA combined mpg: roughly 28–29 mpg.
- Estimated range on a full 12.7-gallon tank: about 350–370 miles.
AWD is valued for weather and terrain, with a modest impact on range.
Practical tips to maximize range
Driving style, cargo, and climate can affect mileage. Here are strategies to get more miles per tank.
- Maintain steady speeds and use cruise control on highways when safe to do so.
- Keep tires inflated to the recommended pressure.
- Limit roof rack use and heavy accessories that increase drag.
With mindful driving, you can approach the upper end of the estimated ranges.
Summary
In most 2021 Trailblazer configurations, a full tank yields roughly 350 to 390 miles, with AWD variants typically toward the lower end of that range. Engine choice and driving conditions remain the key variables when estimating how far you can go on a single tank.
