The Vantage has standard Automatic 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 750S doesn't offer collision warning or crash mitigation brakes.
The Vantage’s 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 750S doesn’t offer a lane departure warning system.
To help make backing out of a parking space safer, the Vantage’s standard Rear Cross Traffic Assist uses sensors in the rear to alert the driver to vehicles approaching from the side and automatically engage the brakes. The 750S doesn’t offer a rear cross-path warning system.
The Vantage’s 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 750S doesn’t offer a driver alert monitor.
Both the Vantage and the 750S have standard driver and passenger frontal airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and rearview cameras.
The Aston Martin Vantage weighs 580 to 688 pounds more than the McLaren 750S. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
