The spectacular body of the car hides many years of Audi wins in the Le Mans racing series and technical solutions have been introduced by experienced Audi Sport Specialists. The model name PB18 e-tron reflects the location of the first-class Pebble Beach and the promising prototype genes of the race-LMP1 Audi R18 e-tron.
At first glance, the new conceptual model resembles an analogue version of the Audi Aicon introduced last year, because they have similar design elements, such as concave side windows, extremely expressive wheel arches and electric propulsion, but their concept differs considerably. The final model is designed as a luxury self-driving car for long journeys and the Audi PB18 e-tron is a special sports racing and street electric vehicle with a unique concept of driving position.

There are no complicated autonomous driving and other unnecessary and weight-increasing accessories in the car, and the driver's seat and the instrument panel with handlebars and pedals are combined in a module that can be slid in the middle of the cab.
Audi design studio Malibu manager Gael Buzyn says: "We want to offer the driver experience that is only possible in sports cars like the Audi R18, so we created the driver's seat in the ideal position of a sports car – in the middle. the PB18 e-tron was practical, so that the driver's seat can be pushed to the normal position on the side and a passenger can sit next to it. "
The Audi PB18 e-tron is based on the principles of the classic sports car with the engine on the rear axle, making it an ideal center of gravity for excellent driving performance. The body of the car is made of aluminum, carbon fiber and composites and comes with advanced and relatively light new generation solid-state electrolyte batteries – all these solutions have a weight of less than 1550 kg.
Conceptual electric vehicle is a classic sports car ratio: 4.53 m long, 2 m wide and only 1.15 m high. Its profile, even down to the massive rear posts and the perpendicular rear window, falls into the body style of the "Shooting brake" and combines coupe and universe functions. This solution not only gave a memorable appearance, but also resulted in a large boat of 460 l, so that it fitted much more than helmets and sportswear.
The concept car has three powerful electric motors: one at the front and two at the rear. The power of the front-end engine reaches 150 kW, the rear wheels are driven by a total of 350 kW engines – the Audi PB18 e-tron is a real quattro car. The total power at the same time is 500 kW, which can be increased to 570 kW for racing. An impressive torque of 830 Nm ensures that the sporty electric vehicle accelerates to 100 km / h. It only takes a little longer than 2 seconds – almost as much as the current prototype of the LMP1 accelerates.
The Audi PB18 e-tron is not only powerful, but also extremely effective. Because electric motors are used for braking, a lot of energy is returned to the battery and the hydraulic braking system is only used for powerful braking. The capacity of the water-cooled solid-state electrolyte battery is 95 kWh, which allows more than 500 kilometers per WLTP cycle to be loaded. The electric vehicle can be charged up to 800 volts, so charging takes only 15 minutes.
The Audi PB18 e-tron can also be charged wirelessly if a load cell with an integrated induction coil is connected to the electricity grid in the parking area. When the electric motor rises above its magnetic field, there is a voltage between it and the bottom of the coil and the car starts charging.
