Compare the2025 Mazda CX-30VS 2025 Kia Sportage PHEV

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 Kia Sportage PHEV 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 Sportage PHEV doesn’t offer knee airbags.

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 Sportage PHEV doesn’t offer a whiplash protection system.

With its standard Smart Brake Support with Pedestrian Detection, the Mazda CX-30 is better at preventing collisions with pedestrians than the Kia Sportage PHEV, according to the Insurance Institute for Highway Safety:

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

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Mazda CX-30 is safer than the Sportage PHEV:

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 Sportage PHEV is only a standard “Top Safety Pick” for 2024, though it hasn’t yet been rated in the updated moderate overlap frontal test, a requirement for the “Top Safety Pick Plus” award.

The CX-30’s 5 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Sportage PHEV runs out after 100,000 miles.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mazda vehicles are more reliable than Kia vehicles. J.D. Power ranks Mazda above average in long-term dependability. With 5 more problems per 100 vehicles in the first three years of ownership, Kia is rated lower.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Mazda vehicles are more reliable than Kia vehicles. Consumer Reports ranks Mazda 3 places higher in reliability than Kia.

The CX-30’s optional 2.5 turbo 4-cylinder produces 62 lbs.-ft. more torque (320 vs. 258) than the Sportage PHEV’s 1.6 turbo 4-cylinder hybrid.

An engine control system that can shut down some of the engine’s cylinders helps improve the CX-30 (except Turbo)’s fuel efficiency. The Sportage PHEV doesn’t offer a system that can shut down part of the engine.

The CX-30 has 1.6 gallons more fuel capacity than the Sportage PHEV (12.7 vs. 11.1 gallons), for longer range between fill-ups.

The CX-30 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Sportage PHEV; it requires you to depend on roadside assistance and your vehicle will have to be towed.

For better maneuverability, the CX-30’s turning circle is 3.8 feet tighter than the Sportage PHEV’s (34.8 feet vs. 38.6 feet).

The Mazda CX-30 may be more efficient, handle and accelerate better because it weighs about 750 to 800 pounds less than the Kia Sportage PHEV.

The CX-30 is 10.5 inches shorter than the Sportage PHEV, making the CX-30 easier to handle, maneuver and park in tight spaces.

The CX-30 has .3 inches more front headroom, .3 inches more front legroom and .3 inches more rear headroom than the Sportage PHEV.

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 Sportage PHEV doesn’t offer a heads-up display.

The CX-30’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Sportage PHEV’s rear power window switches have to be held the entire time to open or close them fully.

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 Sportage PHEV’s manually variable intermittent wipers have to be constantly adjusted.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The CX-30’s headlights were rated “Good” by the IIHS, while the Sportage PHEV’s headlights are rated “Acceptable.”

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 Sportage PHEV doesn’t offer cornering lights.

The CX-30’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Sportage PHEV offers an automatic rear view mirror, but its side mirrors don’t dim.

Insurance will cost less for the CX-30 owner. The Complete Car Cost Guide estimates that insurance for the CX-30 will cost $1145 to $2715 less than the Sportage PHEV over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Mazda CX-30 will be $6352 to $13945 less than for the Kia Sportage PHEV.
