Bahrain provides a very different challenge to Australia, but one of the things it has in common is that is quite a stop-start circuit characterised by longitudinal rather than lateral loads, which also means that it is rear-limited in particular. Because of the abrasive surface and also thermal degradation we would expect more than one pit stop for most drivers, especially as the entire tyre range is softer this year and Bahrain has produced a variety of interesting strategies in the past. The race schedule, with track temperatures that fall considerably during the evening, means that teams need to maximise their learning from the sessions that are most representative and draw the most effective conclusions from the unusual track conditions in the evening.
