For enhanced safety, the front and rear seat shoulder belts of the Toyota Rav4 Prime 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 BMW i3 doesn’t offer pretensioners for the rear seat belts.
For enhanced safety, the front seat shoulder belts of the Toyota Rav4 Prime 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 BMW i3 doesn’t offer height-adjustable seat belts.
The Toyota Rav4 Prime has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The i3 doesn’t offer knee airbags.
The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Pre-Collision System in the Rav4 Prime as “Superior.” The i3 scores only 3 points and is rated only “Advanced.”
The Rav4 Prime 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 i3 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 Rav4 Prime XSE offers optional Parking Assist with Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The i3 doesn’t offer backup collision prevention brakes.
The Rav4 Prime has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The i3 doesn’t offer all-wheel drive.
The Rav4 Prime’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The i3 doesn’t offer a lane departure warning system.
The Rav4 Prime XSE offers an optional Bird’s Eye View Camera to allow the driver to see objects all around the vehicle on a screen. The i3 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 Rav4 Prime’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The i3 doesn’t offer a cross-path warning system.
Both the Rav4 Prime and the i3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
The Toyota Rav4 Prime weighs 926 to 1328 pounds more than the BMW i3. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The Insurance Institute for Highway Safety rates the general design of front seat head restraints for their ability to protect front seat occupants from whiplash injuries. The IIHS also performs a dynamic test on those seats with “good” or “acceptable” geometry. In these ratings, the Rav4 Prime is safer than the i3:

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the Rav4 Prime the rating of “Top Pick” for 2021, a rating granted to only 145 vehicles tested by the IIHS. The i3 is not a “Top Pick.”
