The GranTurismo has standard Automated Emergency Braking, which use 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 DBS doesn't offer collision warning or crash mitigation brakes.
Over 200 people are killed each year when backed over by motor vehicles. The GranTurismo has standard Rear Emergency Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The DBS doesn’t offer backup collision prevention brakes.
The GranTurismo has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The DBS doesn’t offer all-wheel drive.
The GranTurismo’s optional 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. The DBS doesn’t offer a lane departure warning system.
To help make backing out of a parking space safer, the GranTurismo’s optional Rear Cross Path uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The DBS doesn’t offer a rear cross-path warning system.
The GranTurismo’s optional driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The DBS doesn’t offer a driver alert monitor.
The GranTurismo has standard SOS and Assist Call, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The DBS 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 GranTurismo and the DBS 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 blind spot warning systems and around view monitors.
