Tyre engineer unlocks secrets for McLaren - report

There is a secret to McLaren’s recent success, according to the German trade magazine Auto Motor und Sport.

With Lewis Hamilton and then Jenson Button winning the most recent German and Hungarian grands prix, the report said a big reason for the erosion of Red Bull’s dominance is a Japanese engineer.

Hiroshi Imai, who until 2009 was former F1 supplier Bridgestone’s chief engineer, is now working at McLaren on unlocking the secrets of the heavily-degrading Pirellis.

"He seems to have made a breakthrough," said Auto Motor und Sport, revealing that McLaren has worked to better cool the brakes so that the heat is not transferred to the tyres.
