Adrian Newey, Red Bull Racing’s chief technical officer, has expressed his deep concern and anguish over the tragic accident at Las Vegas Motor Speedway on Sunday which resulted in the death of British racing hero, twice Indy 500 winner Dan Wheldon.

During the 1980s Newey was one of the most innovative engineers on the Indycar scene, honing a respected reputation for high speed aerodynamic savvy and original thinking.

But the man behind Sebastian Vettel’s domination of the last two F1 world championship campaigns has admitted that he is personally troubled by the set of circumstances which led to the Wheldon accident.
