The ILX has standard four wheel antilock disc brakes for quicker stops and controlled steering ability, especially under poor traction conditions. Antilock brakes cost extra on the Audi A3.
The ILX has a standard Collision Mitigating Braking System, which uses forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The A3 has a collision warning system without the crash-mitigating brake feature that could reduce stopping distances.
The ILX offers optional AcuraLink, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The A3 doesn’t offer a GPS response system, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the ILX and the A3 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, traction control, electronic stability systems to prevent skidding, collision warning systems, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems and rear cross-path warning.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the ILX the rating of “Top Pick” for 2017, a rating granted to only 213 vehicles tested by the IIHS. The A3 has not been tested, yet.
