Over 200 people are killed each year when backed over by motor vehicles. The GranCabrio Foglore 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 S5 doesn’t offer automatic braking for stationary objects directly to the rear.
The GranCabrio Foglore’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 S5 doesn’t offer a driver alert monitor.
Both the GranCabrio Foglore and the S5 have standard driver and passenger frontal airbags, front side-impact 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, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
The Maserati GranCabrio Foglore weighs 991 to 1311 pounds more than the Audi S5. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
