In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the GLE Coupe are reminded to check the back seat if they opened the rear door before starting out. The Q5 Sportback doesn’t offer a back seat reminder.
The Mercedes GLE Coupe has a standard driver’s side knee airbag mounted low on the dashboard. The knee airbag helps prevent the driver from sliding under the seatbelts or the main frontal airbag; this keeps the driver better positioned during a collision for maximum protection. A knee airbag also helps keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Q5 Sportback doesn’t offer knee airbags.
The GLE Coupe’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 Q5 Sportback doesn’t offer a driver alert monitor.
Both the GLE Coupe and the Q5 Sportback have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, rear cross-path warning and available lane departure warning systems.
The Mercedes GLE Coupe weighs 937 pounds more than the Audi Q5 Sportback. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
