Fernando Alonso (Renault) wowed his home crowd at Valencia as he went fastest in practice for the European Grand Prix.
The Spaniard set the fastest lap of the weekend so far to go top, ahead of Jenson Button and Rubens Barrichello (Brawn), right at the end of a practice that he also caused an accident and had a spin in.
Button ended up second with Barrichello third, confirming that Brawn appears to have front-running pace this weekend.
World champion Lewis Hamilton (McLaren) was last after an early spin damaged his car, and McLaren took the opportunity to begin an early rebuild ahead of the weekend.
