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 RDX are reminded to check the back seat if they opened the rear door before starting out. The Stelvio doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The RDX offers optional Low Speed Autonomous Emergency Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Stelvio doesn’t offer backup collision prevention brakes.
The RDX Advance has a standard Surround-View Camera System to allow the driver to see objects all around the vehicle on a screen. The Stelvio 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 Acura RDX comes with a standard Surround-View Camera System and it also offers an optional rear camera washer to make backing always safe, regardless of road dirt or grime, while the Alfa Romeo Stelvio doesn’t offer a camera washer, requiring manual cleaning.
Both the RDX and the Stelvio 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, plastic fuel tanks, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.
