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 are reminded to check the back seat. The RC doesn’t offer a back seat reminder.
The 2 Series has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The RC doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The 2 Series offers optional Active Park Distance Control that use rear sensors to monitor for objects to the rear and automatically apply the brakes to prevent a collision. The RC doesn’t offer backup collision prevention brakes.
The 2 Series offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The RC 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.
Both the 2 Series and the RC have standard driver and passenger frontal airbags, front 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, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available all wheel drive.
