Barrichello leads Honda 1-2 at Jerez

The Brazilian just edged out his teammate James Rossiter by one tenth of a second as the pair continued to focus on set-up work and evaluation of the new 2007 Bridgestone rubber.

A major downpour in the morning meant that meaningful laps could not be done until just before lunchtime, although Rossiter still managed to complete 108 laps over the course of the day.

Lewis Hamilton, who had been quickest overall on Thursday, was third fastest - just two-tenths behind Rossiter - but his day was marred when he brought out the red flag in the final hour, when his car stopped on track.

Ralf Schumacher continued to focus on adapting the Toyota TF106B chassis to the Bridgestone tyres, having felt that more work was needed at Jerez than had been required at Barcelona last week.

Behind Pedro de la Rosa, Heikki Kovalainen was sixth fastest for Renault despite suffering an engine failure at 1:00pm. The Finn was less than two hundredths of a second faster than teammate Giancarlo Fisichella.

Nick Heidfeld was eighth overall, as his team continued to work on finding a good set-up for the Bridgestone tyres.

Anthony Davidson was ninth quickest, ahead of Timo Glock in the BMW-Sauber and Kamui Kobayashi in the Toyota.

It was a bad day for Ferrari, who saw both Felipe Massa and Luca Badoer stop on the track. The pair ended the day well down the order.

The other red flag of the day was caused when Kazuki Nakajima in the Williams suffered an engine failure at 3:20pm.
