For enhanced safety, the front and second-row seat shoulder belts of the Mazda CX-90 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Volkswagen ID.BUZZ doesn’t offer pretensioners for its second-row seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the CX-90 are reminded to check the back seat if they opened the rear door before starting out. The ID.BUZZ doesn’t offer a back seat reminder.
The Mazda CX-90 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 ID.BUZZ doesn’t offer knee airbags.
With its standard Smart Brake Support, the Mazda CX-90 is better at preventing collisions with pedestrians than the Volkswagen ID.BUZZ, according to the Insurance Institute for Highway Safety:

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Mazda CX-90 achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Volkswagen ID.BUZZ has not been tested.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CX-90. But it costs extra on the ID.BUZZ.
Both the CX-90 and the ID.BUZZ have standard driver and passenger frontal airbags, front side-impact 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, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
The Mazda CX-90 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 an “Acceptable” score in the revised vehicle-to-vehicle crash prevention test. The ID.BUZZ has not yet been fully evaluated by the IIHS for 2026.
