Facts and figures from the record Nordschleife lap
The Volkswagen ID.R made history on 3 June 2019 – with the fastest lap of the Nordschleife ever by an electric car. The prototype is the ultimate “New Energy Vehicle” and has pushed the technology behind a fully-electric drivetrain to its limits during its record-breaking drives. The new electric lap record of 6:05.336 minutes alone is an indication of the outstanding performance produced by driver Romain Dumas (F) at the wheel of the ID.R. The analysis of the data recording also emphatically underlines the pioneering feat of driving and technology. During the ID.R’s lap of the 20.8-kilometre circuit, Dumas was subjected to centrifugal forces equating to about three and a half times his own body weight whilst cornering. The measuring instruments on board the 500-kW (680-PS) ID.R recorded up to 3.49 g.
“Two major differences between the ID.R and the sports car I drive in 24-hour races are the considerably higher cornering speeds and the shorter braking distances,” says Dumas. However, high cornering speeds and extreme braking force produce high forces. During the record-breaking lap, the sensors on board the ID.R regularly recorded values of 3 g and above. The top value of 3.49 g was recorded during the left-right combination in the “Kallenhard” section of the circuit. The most dramatic deceleration came when braking into the “Aremberg” corner, where the carbon-fibre brakes on the ID.R achieved a negative acceleration of 2.7 grams.
Your head suddenly weighs more than 20 kilograms
The high centrifugal forces are a challenge for the driver, and particularly his neck muscles. When stationary, the neck must support roughly five kilograms of head and about 1,500 grams of helmet. The top value of 3.49 g in the “Kallenhard” section of the Nordschleife temporarily increased that weight to over 20 kilograms for Dumas. He prepares for this kind of physical exertion with fitness and strength training. “To simulation that kind of situation, I have fitted an old helmet with weights. I use it to train my neck muscles in my fitness corner in the basement of my house,” says Dumas.
The ID.R hit top speed on its record-breaking lap in the “Fuchsröhre” section, a dip at the end of a longer downhill section. Here, the sensors recorded 273 km/h. Dumas came through the famous “Caracciola-Karussell” at 83 km/h – the lowest speed recorded on his record lap. The average speed for the lap was a mighty 204.96 km/h.
