Fernando Alonso topped the time sheets in a damp first practice session at Barcelona for the Spanish Grand Prix with a time of 1m25.252s.
With much of the session too wet for slicks the pack struggled to get decent track time, many teams taking the opportunity to test their latest developments.
Alonso dominated the time sheets for most of the session while team-mate Felipe Massa pushed up the pace as the teams switched to slick tyres finishing 0.203s behind the sister Ferrari.
While the two Ferrari’s were fastest Toro Rosso’s Jean-Eric Vergne put in an impressive performance to take third spot. An early spin for Romain Grosjean did little to disrupt his session as he finished in fourth place ahead of Adrian Sutil in the Force India.
Lewis Hamilton, Valtteri Bottas, Kimi Raikonen, Nico Rosberg, and Paul Di Resta rounded out the top 10 with one notable team missing – Red Bull – who chose to hold back when the track dried finishing nineteenth and twentieth.
Jenson Button was the only driver to not complete a flying lap, choosing to complete 6 exploratory laps instead.
