How Volkswagen Is Getting the ID.R Ready for the Nurburgring

The electric race car that dominated Pikes Peak will now attempt to set a 'Ring record.

This summer, Volkswagen Motorsport will try to top the record-smashing lap Porsche achieved with its unlimited 919 Evo around the Nürburgring. VW's challenge seems greater because, instead of a Le Mans-winning hybrid dialed up to 11, their attempt will use the Pikes Peak record-breaking ID.R, a fully electric race car weighing 2425 lbs (in Pikes Peak tune).

It seems that the ID.R's official spec sheet hasn't changed a whole lot since its run up the Rockies. Just like before, the dual-motor drivetrain will attack the Nordschleife with a peak output of 680 horsepower. However, full power will only be deployed for the 1.86-mile, almost dead-straight "Döttinger Höhe" section of the circuit. Through the corners, the ID.R will have to conserve and regenerate, to make sure its motors operating at 915 volts won't melt the carbon fiber.

Thermal management is the number one priority with the high-density batteries as well, which are divided into two blocks containing eight modules with 56 cells each. The blocks are air-cooled to keep the package as light as possible, and reach their optimal state of charge at around 86 degrees Fahrenheit. This means Volkswagen will have to pre-heat them before the start of the flying lap, and cool them back once the car is parked.

In the pits, the ID.R will be fast-charged using two systems operating at "a comparatively low power output of 90 kW each." The magnetically-shielded high-voltage cables are fed by glycerin-burning generators, allowing for low heat generation despite the short charging time of around 20 minutes. The rest will be up to Romain Dumas.
