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 Accord are reminded to check the back seat if they opened the rear door before starting out. The A4 doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The Accord Touring has standard Low Speed Braking Control that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The A4 doesn’t offer backup collision prevention brakes.
The Accord’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 A4 doesn’t offer a driver alert monitor.
Both the Accord and the A4 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, rear parking sensors and rear cross-path warning.
