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 Trailseeker are reminded to check the back seat if they opened the rear door before starting out. The R2 doesn’t offer a back seat reminder.
The Trailseeker has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The R2 doesn’t offer front seat center airbags.
The Trailseeker has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The R2 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.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Trailseeker. But it costs extra on the R2.
The Subaru Trailseeker’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Rivian R2 does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
Both the Trailseeker and R2 have rear cross-traffic warning, but the Trailseeker has Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The R2’s Rear Cross-Traffic Warning doesn’t automatically brake.
Both the Trailseeker and the R2 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
