Over 200 people are killed each year when backed over by motor vehicles. The 530e 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 530e has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the A7’s blind spot costs extra.
To help make backing out of a parking space safer, the 530e has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the A7.
The 530e’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 530e 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, lane departure warning systems, rearview cameras, available all wheel drive and night vision systems.
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, with its optional front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the 530e its highest rating: “Top Pick Plus” for 2019, a rating granted to only 114 vehicles tested by the IIHS. The A7 is only a standard “Top Pick” for 2019.
