The Q50 (except )’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The CC doesn’t offer pre-crash pretensioners.
The Insurance Institute for Highway Safety tests front crash prevention systems. With a score of 6 points, IIHS rates the Forward Emergency Braking optional in the Q50 as “Superior.” The CC scores zero, and is rated by the IIHS as having no effective frontal crash prevention.
Over 200 people are killed each year when backed over by motor vehicles. The Q50 (except Pure) offers optional Back-up Collision Intervention which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The CC doesn’t offer backup collision prevention brakes.
The Q50 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The CC doesn’t offer all-wheel drive.
The Q50 (except Pure) offers an optional Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The CC 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 Q50 (except Pure)’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. The CC doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing safer, the Q50 (except Pure)’s optional 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 CC doesn’t offer a cross-path warning system.
Both the Q50 and the CC have standard driver and passenger frontal airbags, front side-impact 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, daytime running lights, rearview cameras and available lane departure warning systems.
