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 2 Series Gran Coupe are reminded to check the back seat if they opened the rear door before starting out. The A3 doesn’t offer a back seat reminder.
When descending a steep, off-road slope, the 2 Series Gran Coupe’s standard Hill Descent Control allows you to creep down safely. The A3 doesn’t offer Hill Descent Control.
The 2 Series Gran Coupe offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The A3 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The 2 Series Gran Coupe has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the A3’s blind spot costs extra.
The 2 Series Gran 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 A3 doesn’t offer a driver alert monitor.
Both the 2 Series Gran Coupe and the A3 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, rearview cameras, available all wheel drive and rear cross-path warning.
