The 330e’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Clarity Plug-In Hybrid doesn’t offer pre-crash pretensioners.
The BMW 330e has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps 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 Clarity Plug-In Hybrid doesn’t offer a front passenger side knee airbag.
The 330e has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Clarity Plug-In Hybrid doesn’t offer a whiplash protection system.
The 330e has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Clarity Plug-In Hybrid 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 330e offers optional Active Park Distance Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Clarity Plug-In Hybrid doesn’t offer backup collision prevention brakes.
The 330e offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Clarity Plug-In Hybrid doesn’t offer all-wheel drive.
To help make backing out of a parking space safer, the 330e’s optional 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 Clarity Plug-In Hybrid doesn’t offer a cross-path warning system.
The 330e’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Clarity Plug-In Hybrid doesn’t offer a driver alert monitor.
Both the 330e and the Clarity Plug-In Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems and rear parking sensors.
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 330e the rating of “Top Pick” for 2021, a rating granted to only 121 vehicles tested by the IIHS. The Clarity Plug-In Hybrid has not been tested, yet.
