The all-electric Audi PB18 e-tron presents a radical vision for the high-performance sports car of tomorrow. Its concept and exciting lines were created in the new Audi design studio in Malibu, California – where the brand’s design is consistently being updated for the future. The abbreviated name “PB18 e-tron” refers both to the Pebble Beach venue for the premiere and to the technological DNA it shares with the successful LMP1 racing car Audi R18 e-tron.
The concept uses three powerful electric motors – one up front and two in the rear. The latter are centrally located between the steering knuckles, each directly driving one wheel via half-shafts. They deliver power output of up to 150 kW to the front axle and 350 kW to the rear – the Audi PB18 e-tron is a true quattro, of course. Maximum output is 500 kW (670 horsepower), with boosting, the driver can temporarily mobilize up to 570 kW (765 hp). The combined torque of up to 830 newton meters (612.2 lb-ft) allows acceleration from 0 to 100 km/h (62 mph) in scarcely more than 2 seconds – a speed that differs only marginally from that of a current LMP1 prototype.
The liquid-cooled solid-state battery has an energy capacity of 95 kWh. A full charge provides for a range of over 500 kilometers (310.7 miles) in the WLTP cycle. The Audi PB18 e-tron is already designed for charging with a voltage of 800 volts. This means the battery can be fully recharged in about 15 minutes.
The Audi PB18 e-tron can also be charged cordlessly via induction with Audi Wireless Charging (AWC). This is done by placing a charging pad with integral coil on the floor where the car is to be parked, and connecting it to the power supply. The alternating magnetic field induces an alternating voltage in the secondary coil fitted in the floor of the car, across the air gap.
