Romain Grosjean topped first practice for the British Grand Prix in wet and soggy conditions as rain poured down on the circuit throughout the session.
The Lotus driver posted a time of 1 minute 56.552 seconds around Silverstone, well over two-tenths quicker than his nearest rival.
With the track deluged by rain and puddles forming on the track, the conditions worsened with spray severely hampering visibility on the soggy track.
Defending champion Sebastian Vettel was 11th, nearly three seconds off the leading pace with Kimi Raikkonen further down in 16th and Jenson Button in 17th.
Fernando Alonso completed just four laps in the 90-minute session but didn’t set a time as the Spaniard preferred to sit out most of the outing in his garage waiting for conditions to improve.
"The main contender during this first free practice session for the British Grand Prix was undoubtedly the rain, which had been predicted and did not disappoint," Ferrari said in a statement. "The session was run entirely in the wet, making it impossible to evaluate updates brought to this event."
Daniel Ricciardo was second in the Toro Rosso ahead of the McLaren of Lewis Hamilton.
Sauber’s Sergio Perez was fourth followed by the Ferrari of Felipe Massa and the Red Bull of Mark Webber. Kamui Kobayashi was seventh with the Mercedes pair of Michael Schumacher and Nico Rosberg next.
Jean-Eric Vergne rounded up the top ten. Neither of the Force India drivers set a time as well.
