The refreshed 2024 Chevy Trailblazer was unveiled in February of 2023, debuting new styling, an overhauled interior, and more standard features. The subsequent 2025 Chevy Trailblazer brings a few updates as well, including a new E85-compatible engine to the lineup. The flex-fuel engine will also be equipped by the 2025 Chevy Trax and 2025 Buick Encore GX, as GM Authority covered previously.
According to GM Authority sources, the 2025 Chevy Trailblazer will offer the new turbocharged 1.2L I3 LBP engine as a replacement for the turbocharged 1.2L I3 LIH gasoline engine offered previously. Although the rest of the powertrain components are unchanged, the turbocharged 1.2L I3 LBP engine will be compatible with E85 fuel, making the 2025 Chevy Trailblazer a flex fuel vehicle. Output from the LBP engine will be identical to that of the LIH engine at 137 horsepower and 162 pound-feet of torque. The 2025 Chevy Trailblazer will continue to offer the turbocharged 1.3L I3 L3T gasoline engine as optional. However, the turbocharged 1.3L I3 L3T gasoline engine is not compatible with E85 fuel.
The turbocharged 1.2L I3 LBP engine will be offered as standard equipment for 2025 Chevy Trailblazer LS FWD and LT FWD models, while the turbocharged 1.3L I3 L3T gasoline engine will be offered as standard on LS AWD, LT AWD, RS, and Activ trims. The E85-compatible 1.2L I3 LBP engine will be available in the U.S. and in Canada, unlike the 2025 Buick Encore GX and 2025 Chevy Trax, both of which will only offer the LBP in the U.S.
E85 is known as a high-ethanol-content fuel, with the percentage of gasoline to ethanol varying between 51 and 83 percent ethanol, depending on the time of year and location. Meanwhile, “regular” gasoline contains roughly 10 percent ethanol.
Vehicles capable of running E85 are known as flex fuel vehicles, and are becoming more common throughout the U.S., in particular in regions where local corn crops provide the source of ethanol for fuel production. The advantages of E85 include a higher resistance to engine knock and a reduced dependence on foreign oil, while the drawbacks include decreased fuel economy and potential issues in colder climates. E85 fuel is not recommended for vehicles that do not have flex fuel capabilities.
