The script for the Hungarian Grand Prix usually includes: extremely hot weather; a dirty, dusty track that rubbers in over the weekend; and little chance for overtaking.
Well, the set-up books were thrown away for last weekend's running at the Hungaroring.
The weather started out cold, and for the first time ever, the race was wet. None of the teams had any data for these conditions, and the preparation for the race weekend was chosen for a hot race. As a result, tyres and set-up were not optimized, and the teams had a learning experience through the race as the track varied between wet and dry.
The Hungaroring circuit is very tight and twisty, with little rubber laid on the track, thus providing poor grip. Teams therefore focus on high downforce - and therefore aerodynamically inefficient - set-ups, as well as on soft mechanical set-ups and fairly soft tyres.
