Thanks! Looks like the Sauber could be the first of the 2017 cars to actually run. What's the filming day limit - 150 km?
Promotional events (of which each team is allowed two per season up to a maximum distance of 100km each) and demonstration events (of which each team is allowed two per season up to a maximum distance of 15km using demonstration tyres) do not count towards this tally.
