For enhanced safety, the front and rear seat shoulder belts of the Mazda CX-30 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Chevrolet Blazer doesn’t offer pretensioners for its rear seat belts.

The Mazda CX-30 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Blazer doesn’t offer a front passenger side knee airbag.

The CX-30 has standard Whiplash-Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The Blazer doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The CX-30 Turbo Premium Plus has standard Rear Smart Brake Support that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The Blazer doesn’t offer backup collision prevention brakes.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CX-30. But it costs extra on the Blazer.

The CX-30 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Blazer’s blind spot costs extra.

To help make backing out of a parking space safer, the CX-30 has standard Rear Cross Traffic Alert and Smart Braking Support - Rear Crossing on the Turbo Premium Plus automatically engages the brakes to help avoid a collision. Chevrolet charges extra for Rear Cross Traffic Alert on the Blazer and the Blazer’s Rear Cross Traffic Alert does not include automatic braking.

The CX-30’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Blazer doesn’t offer a driver alert monitor.

Both the CX-30 and the Blazer have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available around view monitors.

The Mazda CX-30 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The Blazer has not yet been fully evaluated by the IIHS for 2024.

For better maneuverability, the CX-30’s turning circle is 3.9 feet tighter than the Blazer’s (34.8 feet vs. 38.7 feet).

For greater off-road capability the CX-30 has a greater minimum ground clearance than the Blazer LT (8 vs. 7.5 inches), allowing the CX-30 to travel over rougher terrain without being stopped or damaged. The CX-30’s minimum ground clearance is .4 inch higher than on the Blazer RS/Premier (8 vs. 7.6 inches).

Chassis

The Mazda CX-30 may be more efficient, handle and accelerate better because it weighs about 500 to 800 pounds less than the Chevrolet Blazer.

The CX-30 is 1 foot, 6.8 inches shorter than the Blazer, making the CX-30 easier to handle, maneuver and park in tight spaces.

Ergonomics

The CX-30 Premium has a standard heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Blazer doesn’t offer a heads-up display.

The CX-30’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Blazer’s passenger windows don’t close automatically.

The CX-30 Select Sport/Preferred/Carbon/Premium’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Blazer’s manually variable intermittent wipers have to be constantly adjusted.

To help drivers see further while navigating curves, the CX-30 Premium has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The Blazer doesn’t offer cornering lights.

Economic Advantages

Insurance will cost less for the CX-30 owner. The Complete Car Cost Guide estimates that insurance for the CX-30 will cost $815 less than the Blazer over a five-year period.

The CX-30 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the CX-30 will retain 54.31% to 55.58% of its original price after five years, while the Blazer only retains 49.39% to 53.18%.
