Audi A6 e-tron Concept
The Audi A6 e-tron concept made its debut at Auto Shanghai 2021, and in addition to being just an all-electric luxury sports sedan, it has headlights that do more than just illuminate the road. Its Digital Matrix LED front headlights can be used to play video games when parked in front of a wall when recharging the battery. That’s right, it projects virtual landscapes onto the wall and the game can be controlled using a smartphone.

The problem with most drones is that they aren’t designed for underwater use, especially for search and rescue teams. Saver Whale aims to change that. It comes equipped with rugged cameras, sonar technology, several radars, and a radio system for communication. You can deploy this directly from a helicopter precisely where its service is required, while providing a life vest, rope, and first aid kit if necessary.
