The Envista’s corrosion warranty is 1 year longer than the CX-30’s (6 vs. 5 years).

There are almost 2 times as many Buick dealers as there are Mazda dealers, which makes it much easier should you ever need service under the Envista’s warranty.

To reliably power the ignition and other systems and to recharge the battery, the Envista has a 130-amp alternator. The CX-30’s standard 100-amp alternator isn’t as powerful.

Power ranks Buick third in reliability, above the industry average. With 36 more problems per 100 vehicles, Mazda is ranked 7th.

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

In heavy traffic or at stoplights the Envista’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 Buick Envista 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 84.9 cents more per gallon.

The Envista has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The CX-30 doesn’t offer a cap-less fueling system.

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

For better stopping power the Envista’s brake rotors are larger than those on the CX-30:

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

The Envista Preferred’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 Envista’s optional tires have a lower 45 series profile than the CX-30 Select/Preferred/Carbon/Premium’s 55 series tires.

For better ride, handling and brake cooling the Envista Preferred has standard 17-inch wheels. Smaller 16-inch wheels are standard on the CX-30 2.5 S. The Envista’s optional 19-inch wheels are larger than the 18-inch wheels on the CX-30 Select/Preferred/Carbon/Premium.

The Envista 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.

For a smoother ride and more stable handling, the Envista’s wheelbase is 1.6 inches longer than on the CX-30 (106 inches vs. 104.4 inches).

The Envista Sport Touring handles at .80 G’s, while the CX-30 2.5 S Premium pulls only .79 G’s of cornering force in a Motor Trend skidpad test.

The Buick Envista may be more efficient, handle and accelerate better because it weighs about 300 to 400 pounds less than the Mazda CX-30.

The front grille of the Envista 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.

The Envista uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The CX-30 doesn’t offer active noise cancellation.

The Envista has 3.4 cubic feet more passenger volume than the CX-30 (97.5 vs. 94.1).

The Envista has 1.3 inches more front headroom, .2 inches more front legroom, .4 inches more front shoulder room, 2.4 inches more rear legroom and .9 inches more rear shoulder room than the CX-30.

The Envista has a larger cargo volume than the CX-30 with its rear seat up (20.7 vs. 20.2 cubic feet).

The Envista 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 Envista can be unhitched and driven around locally. The CX-30 can’t be towed flat on the ground.

J.D. Power and Associates surveys of service recipients show that Buick service is better than Mazda. J.D. Power ranks Buick third in service department satisfaction. With a 26% lower rating, Mazda is ranked 14th.

The Envista’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The CX-30 does not have an oil pressure gauge.

The power windows standard on both the Envista and the CX-30 have locks to prevent small children from operating them. When the lock on the Envista 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 Envista’s available exterior PIN entry system. The CX-30 doesn’t offer an exterior PIN entry system.

The Envista’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Mazda only offers heated mirrors on the CX-30 Select/Preferred/Carbon/Premium.

J.D. Power and Associates rated the Envista third among small suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The CX-30 isn’t in the top three.
