Diesel spillage delays and reduces opening practice
A spillage of diesel by a circuit cleaning vehicle delayed Friday’s opening free practice session for this weekend’s Russian Grand Prix and reduced it from 90 minutes to one hour.
The worst of the spillage was at Turn Eight on the Sochi Autodrom Olympic Park track created in the coastal cluster facilities built for the 2014 Winter Olympic Games.
After emergency washing of the track, the session began late, four-time world champion German Sebastian Vettel of Ferrari commenting “what a mess” as he drove through the drying patch for the first time.
The track conditions were declared officially as “wet” and this meant drivers ran on intermediate and full-wet tyres to cope with the slippery surface left by the diesel and its aftermath.
