The RC F’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GranTurismo doesn’t offer pre-crash pretensioners.
The Lexus RC F has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The GranTurismo doesn’t offer knee airbags.
The RC F’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the GranTurismo.
The RC F has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the GranTurismo’s blind spot costs extra.
To help make backing out of a parking space safer, the RC F has standard Rear Cross-Traffic Alert, helping the driver avoid collisions. Maserati charges extra for Rear Cross Path on the GranTurismo.
Both the RC F and the GranTurismo 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, crash mitigating brakes, daytime running lights, rearview cameras and available rear parking sensors.
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 RC F the rating of “Top Safety Pick” for 2017, a rating granted to only 207 vehicles tested by the IIHS. The GranTurismo has not been tested, yet.
