British driver Lewis Williamson surprised the GP3 Series field by topping the timesheets on day two of the post-season test in Estoril, on only his first day driving the car.
Formula Renault UK runner-up Williamson joined up with Atech CRS for the second day for the test, one of a few driver changes from the first day, which was topped by Nico Muller. Williamson took the seat vacated by Marlon Stockinger, who replaced Muller at Jenzer Motorsport. Rio Haryanto returned to his regular team Manor Racing, and was replaced at ART Grand Prix by Matias Laine, who moved across from MW Arden. Ivan Lukashevich joined the test with his team Status GP. Miki Monras moved over to Tech 1 Racing, and was replaced at Addax by Antonio Felix Da Costa, who in turn was replaced by debutant Richard Bradley at Carlin. Julian Leal replaced Adriano Buzaid at Addax, and Formula BMW Europe champion Robin Frijns replaced Laine at Arden.
James Calado carried across his impressive form from Day 1 to set the early pace in the morning, but it was Felix Da Costa who ended the morning on top with his new team Addax. Calado ended up second, ahead of Nigel Melker.
Felix Da Costa led for much of the afternoon, but Williamson found his way to the top of the standings before the end of the day. Melker ended the session second, with Felix Da Costa in third. Michael Christensen was fourth for Status, with rookie Willi Steindl in fifth and Pedro Nunes in sixth.
