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 EX30 are reminded to check the back seat if they opened the rear door before starting out. The Q4 e-tron doesn’t offer a back seat reminder.
The EX30 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 Q4 e-tron doesn’t offer front seat center airbags.
The EX30 has a standard Whiplash Protection System (WHIPS), which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Q4 e-tron doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The EX30 Ultra 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 Q4 e-tron doesn’t offer automatic braking for stationary objects directly to the rear.
The EX30’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 Q4 e-tron doesn’t offer a driver alert monitor.
Both the EX30 and the Q4 e-tron 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, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.
