True to the adverse weather forecasts, rain spoilt the final day of running on Thursday at Jerez.
It was wet all day at the Spanish circuit, with McLaren opting to limit Fernando Alonso’s running to just nine laps and Renault sharing just a handful of laps between its drivers.
For the record, BMW’s Nick Heidfeld topped the order, but his best lap was ten seconds off a quick dry-weather time.
Williams, Ferrari, Honda, Toyota and Red Bull also braved the conditions, ahead of a quick weekend dash to Barcelona to resume running on Monday morning.
It will be the penultimate test of the pre-season, with Bahrain scheduled as the last stop before Melbourne.
