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 Altima are reminded to check the back seat if they opened the rear door before starting out. The A3 doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The Altima offers optional Rear Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The A3 doesn’t offer backup collision prevention brakes.
The Altima Platinum has a standard Around View Monitor to allow the driver to see objects all around the vehicle on a screen. The A3 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.
The Altima’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 A3 doesn’t offer a driver alert monitor.
Both the Altima and the A3 have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, rearview cameras, available daytime running lights, blind spot warning systems 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 vehicle-to-vehicle front crash prevention system, with its optional vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Altima its highest rating: “Top Pick Plus” for 2021, a rating granted to only 74 vehicles tested by the IIHS. The A3 has not been tested, yet.
