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 500e doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Audi Q4 e-tron Sportback are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Fiat 500e doesn’t offer height-adjustable seat belts.
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 Q4 e-tron Sportback are reminded to check the back seat if they opened the rear door before starting out. The 500e doesn’t offer a back seat reminder.
The Q4 e-tron Sportback has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 500e 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 Q4 e-tron Sportback has standard Pre Sense Rear that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 500e doesn’t offer backup collision prevention brakes.
The Q4 e-tron Sportback has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 500e doesn’t offer all-wheel drive.
The Q4 e-tron Sportback Premium Plus has a standard Top View Camera System to allow the driver to see objects all around the vehicle on a screen. The 500e 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.
The Q4 e-tron Sportback has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the 500e’s blind spot costs extra.
To help make backing out of a parking space safer, the Q4 e-tron Sportback has standard Rear Cross-Traffic Assist and Automatic Brake Activation automatically engages the brakes to help avoid a collision. Fiat charges extra for Rear Cross Path Detection on the 500e and the 500e’s Rear Cross Path Detection does not include automatic braking.
Both the Q4 e-tron Sportback and the 500e have standard driver and passenger frontal airbags, front side-impact 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 and rearview cameras.
The Audi Q4 e-tron Sportback weighs 1898 pounds more than the Fiat 500e. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
