For enhanced safety, the front seat shoulder belts of the Subaru Solterra are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Tesla Model S doesn’t offer height-adjustable 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 Solterra are reminded to check the back seat if they opened the rear door before starting out. The Model S doesn’t offer a back seat reminder.
The Solterra 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 Model S 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.
Over 200 people are killed each year when backed over by motor vehicles. The Solterra has a standard Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Model S doesn’t offer backup collision prevention brakes.
When descending a steep, off-road slope, the Solterra’s standard Downhill Assist Control allows you to creep down safely. The Model S doesn’t offer Downhill Assist Control.
The Solterra Limited/Touring has a standard 360-degree Surround-View Camera to allow the driver to see objects all around the vehicle on a screen. The Model S only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
To help make backing out of a parking space safer, the Solterra’s standard rear cross-path warning system uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Model S doesn’t offer a rear cross-path warning system.
The Solterra has standard STARLINK Safety and Security, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model S doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Solterra and the Model S have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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 and driver alert monitors.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Solterra its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 29 vehicles tested by the IIHS. The Model S is not even a standard “Top Safety Pick.”
