On the EPA test cycle the Trailblazer gets better mileage than the CX-30:

In heavy traffic or at stoplights the Trailblazer’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The CX-30 doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Chevrolet Trailblazer uses regular unleaded gasoline. The CX-30 with the 2.5 turbo 4-cylinder engine requires premium for maximum efficiency, which can cost on average about 82.8 cents more per gallon.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Chevrolet Trailblazer higher (7 out of 10) than the Mazda CX-30 (5 to 7). This means the Trailblazer produces up to 8 pounds less smog-producing pollutants than the CX-30 every 15,000 miles.

A nine-speed automatic is standard on the Chevrolet Trailblazer 1.3 turbo 3-cylinder AWD, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the CX-30.

The Trailblazer has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The CX-30 doesn’t offer a CVT.

The Trailblazer stops shorter than the CX-30:

For better traction, the Trailblazer has larger standard tires than the CX-30 (225/60R17 vs. 215/65R16). The Trailblazer RS’ tires are larger than the largest tires available on the CX-30 (245/45R19 vs. 215/65R16).

The Trailblazer LS/LT/ACTIV’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the CX-30 2.5 S’ standard 65 series tires. The Trailblazer RS’ tires have a lower 45 series profile than the CX-30 Select/Preferred/Carbon/Turbo/Premium’s 55 series tires.

The Trailblazer has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The CX-30 doesn’t offer vehicle monitored tire inflation.

The Trailblazer RS AWD handles at .80 G’s, while the CX-30 Premium pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The Chevrolet Trailblazer may be more efficient, handle and accelerate better because it weighs about 250 to 400 pounds less than the Mazda CX-30.

The front grille of the Trailblazer uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The CX-30 doesn’t offer active grille shutters.

To make loading groceries and cargo easier when your hands are full, the Trailblazer ACTIV/RS’ liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The CX-30 doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The Trailblazer has a 1000 lbs. towing capacity. The CX-30 has no towing capacity.

The Trailblazer AWD can be flat towed on all four wheels (dinghy towed), allowing recreational vehicle owners to bring it with them on the road. When they reach their destination, the Trailblazer can be unhitched and driven around locally. The CX-30 can’t be towed flat on the ground.

The power windows standard on both the Trailblazer and the CX-30 have locks to prevent small children from operating them. When the lock on the Trailblazer is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The CX-30 prevents the driver from operating the other windows just as it does the other passengers.

In case you lock your keys in your vehicle, or don’t have them with you, you can let yourself in using the Trailblazer’s available exterior PIN entry system. The CX-30 doesn’t offer an exterior PIN entry system.

To improve rear visibility by keeping the rear window clear, the Trailblazer has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the CX-30 only has an intermittent setting, so in a hard rain visibility isn’t as good.
