Pirelli motorsport director Paul Hembery admits that he is not certain of how the Pirelli tyres will react in Hungary.
Last year's race at the Hungaroring was affected by rain and as such Pirelli were unable to glean maximum data from the track in their first year back in the sport.
While the circuit may be slow, Hembery warns that this does not mean that it will be easy on the tyres.
"Hungary will provide a very stark contrast to the circuits that we have just come from, being the slowest permanent track on the calendar," he said.
"This does not make it any less demanding on the tyres though: in fact a twisty and slippery circuit will often put more heat through the tyre than a fast and flowing layout as the tyre is moving around more - particularly when the ambient temperatures are high. Having said that, in Hungary last year we saw some wet weather, so it's important not to make any assumptions.
"Consequently, we are still lacking some information about the performance of our slick tyres under race conditions at the Hungaroring. Balancing the demands of speed and durability will be key to getting the most out of the tyres in Hungary, in order to keep degradation under control.
"Overtaking is traditionally difficult, so the drivers have an opportunity to use strategy in order to gain track position. Because of this, the work done in free practice will be vital when it comes to preparing the race strategy: an opportunity that has been denied to the teams recently because of bad weather in the build-up to the last two grands prix."
