In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Kia Sportage PHEV achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Buick Envision has not been tested.

The Sportage PHEV’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 Envision doesn’t offer a driver alert monitor.

Both the Sportage PHEV and the Envision have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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 and available around view monitors.

The Kia Sportage PHEV has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2026 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, a “Good” score in the revised pedestrian crash prevention test, and a “Good” score in the revised vehicle-to-vehicle crash prevention test. The Envision has not yet been evaluated by the IIHS for 2026.

The Sportage PHEV comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Envision’s 3-year/36,000-mile basic warranty expires 2 years or 24,000 miles sooner.

Kia’s powertrain warranty covers the Sportage PHEV 5 years and 40,000 miles longer than Buick covers the Envision. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Envision ends after only 5 years or 60,000 miles.

J.D. Power and Associates’ 2025 Initial Quality Study of new car owners surveyed provide the statistics that show that Kia vehicles are better in initial quality than Buick vehicles. J.D. Power ranks Kia above average in initial quality. With 2 more problems per 100 vehicles, Buick is rated lower.

As tested in Consumer Reports the Kia Sportage PHEV is faster than the Buick Envision:

On the EPA test cycle the Sportage PHEV running on electricity gets better mileage than the Envision (87 city/78 hwy MPGe vs. 22 city/28 hwy).

On the EPA test cycle the Sportage PHEV running its gasoline engine gets better fuel mileage than the Envision (35 city/36 hwy vs. 22 city/28 hwy).

The Sportage PHEV can travel with zero emissions for 34 miles. The Envision can’t move without running its internal combustion engine.

Regenerative brakes improve the Sportage PHEV’s fuel efficiency by converting inertia back into energy instead of wasting it. The Envision doesn’t offer a regenerative braking system.

The Sportage PHEV has a standard locking fuel door, which locks and unlocks with the power locks. The fuel filler door is not lockable on the Envision. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

For better stopping power the Sportage PHEV’s front brake rotors are larger than those on the Envision:

The Sportage PHEV’s tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Envision Preferred’s standard 60 series tires.

For better ride, handling and brake cooling the Sportage PHEV has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Envision Preferred.

The Sportage PHEV has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Envision doesn’t offer variable-assist power steering.

The Sportage PHEV has 1 inch more front legroom, .8 inches more front shoulder room, .2 inches more rear headroom, .2 inches more rear legroom and 6 inches more rear hip room than the Envision.

For enhanced passenger comfort on long trips the Sportage PHEV’s rear seats recline. The Envision’s rear seats don’t recline.

The Sportage PHEV has a much larger cargo volume with its rear seat up than the Envision with its rear seat up (34.5 vs. 25.2 cubic feet). The Sportage PHEV has a much larger cargo volume with its rear seat folded than the Envision with its rear seat folded (65.5 vs. 52.7 cubic feet).

The Sportage PHEV’s standard towing capacity is much higher than the Envision’s (2000 vs. 1500 pounds).

Heated windshield washer nozzles are standard on the Sportage PHEV X-Line Prestige to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Envision doesn’t offer heated windshield washer nozzles.

Consumer Reports rated the Sportage PHEV’s headlight performance “Good,” a higher rating than the Envision’s headlights, which were rated “Fair.”

Both the Kia Sportage PHEV and Buick Envision offer exterior mirrors that can be folded to provide convenience. The Sportage PHEV offers available power folding mirrors, which allow for easy, one-touch folding or unfolding at the driver’s discretion. This provides added convenience when maneuvering or parking, as well as when walking past the parked vehicle. In comparison, the Envision’s foldable mirrors are manual, requiring the driver to get out and physically fold them once parked and unfold them before getting in.

The Sportage PHEV has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the Envision.

The Sportage PHEV X-Line Prestige’s Smart Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Smart Parking Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Envision Avenir’s automatic parking system does not offer parking by remote control.
