For enhanced safety, the front and rear seat shoulder belts of the Aston Martin DBX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Maserati Grecale doesn’t offer pretensioners for its rear seat belts.
The DBX’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 Grecale.
The DBX 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 Grecale’s blind spot costs extra.
To help make backing out of a parking space safer, the DBX has standard Rear Cross Traffic Warning and automatically engage the brakes. Maserati charges extra for Rear Cross Path on the Grecale and the Grecale’s Rear Cross Path does not include automatic braking.
Both the DBX and the Grecale have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights and rearview cameras.
The Aston Martin DBX weighs 471 to 832 pounds more than the Maserati Grecale. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
