Amid a run of races on unconventional circuits since May's Spanish Grand Prix at Barcelona, it's been difficult to get a proper read on what kind of progress Formula 1 teams are making in their relentless aerodynamic development war.
The unique demands of Monaco require specialised high-downforce packages, with little regard paid to the consequent drag penalty; Montreal and Baku require more of a compromise on set-up for the long straights. The cornering challenges at each venue are all relatively low-speed, and the track surfaces smooth, requiring particular technical approaches that are not really representative of the majority of tracks on the calendar.
But the last two races have been held on what might be called 'conventional' F1 circuits. Austria's Red Bull Ring is a medium-downforce circuit with a couple of high-speed corners; Silverstone has a blend of high-speed sweeps and long straights that allow F1 cars to really flex their muscles and place the onus on efficient aerodynamics.
