The CX-3 has standard Whiplash-Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash-Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The QX30 doesn’t offer a whiplash protection system.

To help make backing safer, the CX-3’s cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The QX30 doesn’t offer a cross-path warning system.

The CX-3 has standard E911 Automatic Emergency Notification, which uses a global positioning satellite (GPS) receiver and a cellular system to send emergency personnel to the scene if any airbags deploy. The QX30 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the CX-3 and the QX30 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front-wheel drive, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive and lane departure warning systems.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, with its optional front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the CX-3 the rating of “Top Pick” for 2018, a rating granted to only 90 vehicles tested by the IIHS. The QX30 has not been tested, yet.

The CX-3 offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The QX30 doesn’t offer a remote starting system.

The CX-3 Grand Touring has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The QX30 doesn’t offer a heads-up display.

To improve rear visibility by keeping the rear window clear, the CX-3 has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the QX30 only has an intermittent setting, so in a hard rain visibility isn’t as good.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the CX-3 has standard extendable sun visors. The QX30 doesn’t offer extendable visors.

On extremely cold winter days, the CX-3 Grand Touring’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The QX30 doesn’t offer a heated steering wheel.
