For enhanced safety, the front and rear seat shoulder belts of the Volkswagen ID.4 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 Alfa Romeo Tonale doesn’t offer pretensioners for its rear seat belts.
The ID.4’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Tonale doesn’t offer pre-crash pretensioners.
Both the ID.4 and Tonale have child safety locks to prevent children from opening the rear doors. The ID.4 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Tonale’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The ID.4 has a standard Automatic Post-Collision Braking System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Tonale doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
The Volkswagen ID.4’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Alfa Romeo Tonale does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
Both the ID.4 and Tonale have rear cross-traffic warning, but the ID.4 has Rear Traffic Alert (automatically applies the brakes) to better prevent a collision when backing near traffic. The Tonale’s Rear Cross-Path Detection doesn’t automatically brake.
Both the ID.4 and the Tonale 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, driver alert monitors and available around view monitors.
The Volkswagen ID.4 weighs 442 to 1164 pounds more than the Alfa Romeo Tonale. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
