Volkswagen ID. R uses DRS Formula 1 technology for Nürburgring run

Volkswagen has set itself a new challenge with the ID. R this year – the Nürburgring-Nordschleife instead of Pikes Peak. A race track instead of a hill climb. Full-throttle sections instead of hair-pins. Because of this, the fully electric-powered ID. R has been continuously developed with respect to its aerodynamics.

“Though almost identical in length at roughly 20 kilometres, the Nordschleife presents a completely different challenge for aerodynamics in comparison to the hill climb at Pikes Peak,” says François-Xavier Demaison, Technical Director of Volkswagen Motorsport. “In the USA it was all about maximum downforce, but because the speeds are a lot higher on the Nordschleife, the most efficient possible battery use is of much greater importance with regard to the aerodynamic configuration.”

On the Nordschleife, it is not primarily about downforce, but low drag as well. Furthermore, the air in the Eifel, which sits about 600 metres above sea level, is much denser in comparison to Pikes Peak, where the finish line is 4,302 metres high. “This results in completely different basic data for the measurements of the aerodynamic aids,” explains Hervé Dechipre, the engineer responsible for the ID. R’s aerodynamics.

As well as an adapted floor and a new spoiler at the front of the vehicle, the ID. R will also sport a newly designed rear wing. It will be much lower than the variant used at Pikes Peak, in order to provide less surface resistance to the flow of air. The new multi-wing rear of the ID. R will nevertheless produce high downforce in the medium-fast turns of the 73-corner Nordschleife.

A difference to Formula 1: saving energy instead of overtaking

To further reduce the drag in certain sections, the rear wing will deploy technology known from its use in Formula 1 – the so-called Drag Reduction System (DRS). …continue reading
