When descending a steep, off-road slope, the X2’s standard Hill Descent Control allows you to creep down safely. The Model Y doesn’t offer Hill Descent Control.
The X2 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The Model Y 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.
To help make backing out of a parking space safer, the X2’s standard Cross Traffic Warning with braking function uses sensors in the rear to alert the driver to vehicles approaching from the side and automatically engage the brakes. The Model Y doesn’t offer a rear cross-path warning system.
The X2 has standard BMW Assist, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model Y doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the X2 and the Model Y 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, 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 and rearview cameras.
