The A5’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 A5 and Integra have child safety locks to prevent children from opening the rear doors. The A5 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.
The A5 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Integra doesn’t offer front seat center airbags.
The A5 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Integra 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.
The A5 has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Integra doesn’t offer all-wheel drive.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The A5 has Car-to-X Services, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Integra doesn’t offer a system that can receive automated systems from infrastructure.
The A5 offers an optional 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 A5 and Integra have rear cross-traffic warning, but the A5 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 A5 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, rear cross-path warning and driver alert monitors.
The Audi A5 weighs 871 to 1017 pounds more than the Acura Integra. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
