Inspired by the Audi R18 e-tron race car, the PB18 is powered by a trio of electric motors for a peak combined system output of 570kW and 800Nm, resulting in a vehicle weighing less than 1550kg.

Channelled through an all-electric take on Audi's quattro system, the PB18 e-tron claims a 0-100km/h sprint time of a little over 2.0 seconds.

The 95kWh liquid-cooled solid-state battery provides a range of over 500km and can be fully recharged in around 15 minutes with an 800-volt charger. It is also compatible with Audi Wireless Charging, which enables the car to be parked over a charging pad and re-powered without plugging in. One of the PB18 e-tron's most unique features is the integrated driver's seat and cockpit, which can slide laterally within the car. This allows the driver to be positioned at the centre of the cabin for racetrack driving, or in a conventional position for road use.

Further racing inspiration can be seen in the “lateral bridge” design of the front hood, which enhances aerodynamics as well as allowing the driver to see directly onto the road beneath.

A transparent OLED surface is mounted within the windscreen, which can use navigation and vehicle electronics data to display information such as the ideal driving line of the next corner into the driver's field of vision.

Although it has only been released as a concept, the PB18 e-tron has been flagged as a possible replacement for the existing second generation R8.
