Over 200 people are killed each year when backed over by motor vehicles. The GranCabrio 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 Vantage doesn’t offer automatic braking for stationary objects directly to the rear.
The GranCabrio has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Vantage doesn’t offer all-wheel drive.
The GranCabrio 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 Vantage 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 GranCabrio and the Vantage have standard driver and passenger frontal airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors, rear cross-path warning and driver alert monitors.
The Maserati GranCabrio weighs 567 pounds more than the Aston Martin Vantage. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
