The Q60 Red Sport 400’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The 718 Cayman doesn’t offer pre-crash pretensioners.
Over 200 people are killed each year when backed over by motor vehicles. The Q60 Luxe/Red Sport 400 has standard Back-up Collision Intervention that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The 718 Cayman doesn’t offer backup collision prevention brakes.
The Q60 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 718 Cayman doesn’t offer all-wheel drive.
The Q60 Luxe/Red Sport 400’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The 718 Cayman doesn’t offer a lane departure warning system.
The Q60 Luxe/Red Sport 400 has a standard Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The 718 Cayman 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.
To help make backing out of a parking space safer, the Q60 Luxe/Red Sport 400’s standard rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 718 Cayman doesn’t offer a cross-path warning system.
Both the Q60 and the 718 Cayman have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes and blind spot warning systems.
The Infiniti Q60 weighs 471 to 1013 pounds more than the Porsche 718 Cayman. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
