The stunning Audi PB18 e-tron concept, which made its debut at Monterey Car Week in 2018, is getting the green light. Audi Global CEO, Bram Schot, in an interview with Autoweek Netherlands, said the all-electric supercar should show up sometime in the next year or two, though, just 50 examples will make their way to production.
For race track and road
In the Audi PB18 e-tron, the driver is the one steering and stepping on the gas or brake pedal. There are therefore no complex systems for piloted driving on board and no comfort features to add weight. In their place are a driver’s seat and cockpit that are integrated into an inner monocoque shell that can be slid laterally. When driven solo, the monocoque can be positioned in the center of the interior as in a monoposto – the perfect location for the racetrack. This is made possible not least by the by-wire design of the steering and pedals; a mechanical connection of the control elements is not needed.
Gael Buzyn is Head of the Audi Design Loft in Malibu – where the Audi PB18 e-tron was born. He describes the most important item in the specifications: “We want to offer the driver an experience that is otherwise available only in a racing car like the Audi R18. That’s why we developed the interior around the ideal driver’s position in the center. Nevertheless, our aim was to also give the PB18 e-tron a high degree of everyday usability, not just for the driver, but also for a potential passenger.”
Three electric motors and quattro drive
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, with boosting, the driver can temporarily mobilize up to 570 kW. The combined torque of up to 830 newton meters (612.2 lb-ft) allows acceleration from 0 to 100 km/h (62.1 mph) in scarcely more than 2 seconds – a speed that differs only marginally from that of a current LMP1 prototype.
In normal road traffic, the driver can limit the maximum speed in favor of range. This limitation is easy to deactivate on the racetrack and can be adapted to local conditions.
The focus is on not just powerful performance but also maximum efficiency. While being driven, the Audi PB18 e-tron recovers large amounts of energy: up to moderate braking, the electric motors are solely responsible for decelerating the vehicle. The hydraulic brakes only come into play for heavy braking.
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.
Ladies and gentlemen, the future has arrived.
