To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q4 e-tron Sportback. But it costs extra on the ID.4.
The Q4 e-tron Sportback offers an optional Top View Camera System to allow the driver to see objects all around the vehicle on a screen. The ID.4 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 Q4 e-tron Sportback and the ID.4 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, 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 and rear cross-path warning.
