The A3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Integra doesn’t offer pre-crash pretensioners.
Both the A3 and Integra have child safety locks to prevent children from opening the rear doors. The A3 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Integra’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Audi A3 achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Acura Integra has not been tested.
The A3 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Integra doesn’t offer all-wheel drive.
The A3 Premium Plus has a standard Top View Camera System to allow the driver to see objects all around the vehicle on a screen. The Integra 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.
Both the A3 and Integra have rear cross-traffic warning, but the A3 has Automatic Brake Activation (automatically applies the brakes) to better prevent a collision when backing near traffic. The Integra’s Rear Cross Traffic Monitor doesn’t automatically brake.
Both the A3 and the Integra have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.
