Pirelli motorsport director Paul Hembery believes that this weekend’s German Grand Prix is “a bit of an unknown quantity” for Formula 1’s tire supplier after a two-year absence from Hockenheim.
Last year’s German Grand Prix was due to take place at the Nürburgring before the deal fell through, causing the race to drop off the calendar.
F1 returns to Germany this weekend at Hockenheim where Pirelli has just two races worth of data (2012 and 2014), significantly less than most other events this season.
“Hockenheim will be a bit of an unknown quantity,” Hembery said.
“We’ve not raced there for two years, and even before then it was a race that alternated with the Nürburgring, so everybody is lacking historical data compared to other venues we visit.
“The cars are obviously going a lot quicker than they were in 2014, which is why we have introduced a tyre nomination that is a step harder compared to last time.
“The most notable feature of that 2014 race was the variable weather: on race day track temperatures were 20 degrees cooler than they had been on the very hot qualifying day.
“With the German Grand Prix taking place at the same time of year again, there is obviously the potential for similar variation.”
Pirelli has nominated the medium, soft and super-soft tires for the weekend.
