Lotus demonstration to wow Malaysia ahead of Grand PrixAmerican rookie Gabby Chaves set the quickest time during the second day of the GP3 test at Silverstone on Wednesday.

The 17-year-old Addax driver posted a lap of 1m50.799sec late in the morning session, displacing Arden's Lewis Williamson, who had topped the time sheets since mid-morning. Just one second separated the first 19 drivers.

Rain was forecast for the afternoon but it arrived during the final minutes of the morning session. Running on wet-weather Pirelli tires, Lotus ART's Valtteri Bottas and James Calado initially set the pace in an afternoon session which had to be red-flagged several times.

Alexander Sims ultimately set the fastest wet lap, but as the track dried out Lewis Williamson undercut his time by almost a second. The session ended early because of another red flag.
