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 Highlander Hybrid 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 Toyota Highlander Hybrid 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 Q4 e-tron doesn’t offer knee airbags.
The Highlander Hybrid has standard Whiplash Injury Lessening Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Seats system 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 Highlander Hybrid Limited/Platinum has standard Automated Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Q4 e-tron doesn’t offer backup collision prevention brakes.
The Highlander Hybrid’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 Highlander Hybrid 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, available all wheel drive and around view monitors.
