Braking performance critical at the Norisring

After a four-week break, the DTM heads to the Norisring in Nuremberg this coming weekend. At just 2.3-kilometres long, the legendary street circuit is the shortest on the calendar and enjoys cult status amongst drivers and fans as “Germany’s Monaco” thanks to its special flair and often very spectacular race action. On the smooth road surface, wear on the Hankook race tyres in recent years has been minimal.

Nuremberg/Germany, 26 June 2014 – A decisive factor for success on the Norisring will be the braking performance. At top speeds of around 260 kilometres per hour, pilots have to brake hard before the two hairpins and the chicane, at times down to 45 km/h. “On the Norisring it’s all about braking and accelerating. Because the circuit is really bumpy it’s imperative that the vehicle is set up perfectly to maintain surface contact under braking and to prevent bouncing in the se passages,” explains Hankook’s DTM engineer Christophe Stucki.

The race tyres of DTM’s exclusive partner Hankook provide the necessary traction so that the pilots immediately reach top speed again after exiting the slow corners. It is vital that the Ventus Race and the Ventus Race Plus rubber reach the ideal operating temperature of 90 to 110 degrees as quickly as possible. Christophe Stucki: “The teams can achieve this by adjusting the camber or spring settings. Higher air pressure also expedites the warming of the tyres. This is particularly important in qualifying where drivers need to turn fast laps immediately.”

Structurally, the race tyres are put under very little stress on the Norisring. In the slow corners, minimal centrifugal forces act on the Hankook tyres, and the kerbs are very low. But there is one special feature for which drivers must be prepared. The track in the heart of Nuremberg is normally well used by city traffic, with all its wear and tear. The road surface is constantly changing and every year new repairs to the blacktop are undertaken. “There is a lot of dirt on the circuit especially early on in the race weekend. This is usually cleaned up after the first practice, but only on the racing line. And the pilots should never veer from the ideal line, otherwise they could have a close encounter with the wall at the exit of the Schöller-S on the back straight,” explains Hankook’s DTM engineer.
