To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the X1. But it costs extra on the UX.
The X1 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The UX 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 X1 and UX have rear cross-traffic warning, but the X1 has Cross Traffic Warning with braking function (automatically applies the brakes) to better prevent a collision when backing near traffic. The UX’s Rear Cross-Traffic Alert doesn’t automatically brake.
Both the X1 and the UX 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, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
