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 A7 doesn’t offer a whiplash protection system.
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 A7 doesn’t offer backup collision prevention brakes.
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 A7 doesn’t offer a driver alert monitor.
Both the 330e and the A7 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems, blind spot warning systems, rear parking sensors and rear cross-path warning.
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 front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the 330e its highest rating: “Top Pick Plus” for 2019, a rating granted to only 107 vehicles tested by the IIHS. The A7 is only a standard “Top Pick” for 2019.
