The Q4 e-tron Sportback’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Model Y doesn’t offer pre-crash pretensioners.
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 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 Q4 e-tron Sportback’s standard rear cross-path warning system uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Model Y doesn’t offer a rear cross-path warning system.
The Q4 e-tron Sportback has a standard Audi Connect CARE, 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 Q4 e-tron Sportback and the Model Y 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, 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.
The Audi Q4 e-tron Sportback weighs 485 to 520 pounds more than the Tesla Model Y. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
