Lewis Hamilton says trying to judge the pecking order at the German Grand Prix from Friday practice may be a futile exercise, with changing weather conditions set to throw the order in the air.
While Mercedes have put fixes in place for the cooling issues which hampered them in Austria, the searing track temperatures in Germany made tyre wear excessive – although this is not expected to be seen over the weekend, when lower temperatures and rain are forecast.
"It's not been the best of days in terms of the heat, but pretty straightforward otherwise," Hamilton said.
