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 EX90 are reminded to check the back seat when a sensor determines the back seat is occupied. The Q8 e-tron doesn’t offer a back seat reminder.
The Volvo EX90 (except 6-Passenger) offers an optional built in child booster seat. It’s more crash worthy than an added child seat because of its direct attachment to the seat. Audi doesn’t offer the convenience and security of a built-in child booster seat in the Q8 e-tron. Their owners must carry a heavy booster seat in and out of the vehicle; EX90 owners can just fold their built-in child seat up or down.
The EX90 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Q8 e-tron doesn’t offer front seat center airbags.
Over 200 people are killed each year when backed over by motor vehicles. The EX90 has standard CTA Auto Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Q8 e-tron doesn’t offer automatic braking for stationary objects directly to the rear.
The EX90’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 Q8 e-tron doesn’t offer a driver alert monitor.
Both the EX90 and the Q8 e-tron have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee 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, post-collision automatic braking systems, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.
