TrueDelta Reviews the Real Gas Mileage of the Chevrolet Trax

Chevrolet Trax Real Gas Mileage: Pros
Year	Comment
2015	The Chevrolet Trax isn't quite the segment's fuel economy champ--that honor goes to the new Honda HR-V--but it's close. EPA ratings are 26 mpg city and 34 mpg highway with front-wheel drive (FWD), and 24/31 with all-wheel drive (AWD). With a CVT instead of a conventional automatic, and with a 1.8-liter four-cylinder engine rather than a turbocharged 1.4-liter, the Honda manages 28/35 and 27/32, respectively. You can get an engine as small as the Trax's in the Jeep and FIAT, but only paired with a manual transmission (not offered in the Trax). Even with this engine the Jeep's EPA ratings are 24/31 (though with either drivetrain, and so more competitive with AWD). A nine-speed automatic is only available with a non-turbocharged 2.4-liter four-cylinder engine. The additional, taller ratios balance out the larger engine size, for EPA ratings of 22/31 with FWD and 21/29 with AWD. The FIAT 500X fares a little better with the same powertrains. EPA ratings are 25/34 with the 1.4T and manual transmission (not offered with AWD). With the 2.4 and nine-speed automatic transmission the 500X's EPA ratings are 22/31 with FWD and 21/30 with AWD. In my real-world driving, the Trax's trip computer regularly reported numbers much better than its EPA ratings: between 30 and 40 mpg in the suburbs (and most often 36-37), and just over 40 mpg on the highway. It's not hard to see how the Trax's fuel economy can excel in highway driving. Cruising in sixth gear, the small four spins only 2,000 rpm at 60 mph. I observed the best fuel economy numbers with very leisurely acceleration and braking. Push the Trax hard, and the tiny turbo will force as much fuel and air into the cylinders as it can, severely impacting fuel economy in the process. If you want to get impressive mpg averages out of a turbocharged engine, the turbo is been seen as something to be used only when quick acceleration is really needed, not when pulling away from every traffic light. see full Chevrolet Trax review
