Brawn GP maintained their good form in the final pre-season test with some more impressive times in Jerez.
The British team set the fastest lap for the third straight session with Rubens Barrichello clocking a time of one minute 19.236 seconds.
Renault's Fernando Alonso had a less successful day after crashing into a tyre wall which damaged his car and delayed the session by half an hour.
He eventually finished just under six-tenths of a second behind Barrichello.
"Unfortunately I made a mistake this morning which was a shame as we lost a lot of track time, but sometimes this happens in testing when you are looking for the limits of the car," said Alonso.
"Tomorrow we will try and recover some of the time we lost today."
Nico Hulkenberg of Williams completed Sunday's line-up, with McLaren joining the test on Monday.
There are just four teams taking part in the final test before the 2009 season starts with the Australian Grand Prix in Melbourne on 29 March.
Last week, Barrichello was over a second quicker than the field, with world champion Lewis Hamilton almost two seconds and five kilometres an hour down on the veteran Brazilian.
Brawn's performances are remarkable given it is only just over a week since the former Honda team confirmed it would be on the grid for the new season.
