Williams run radical rear wing in testing


Williams ran a radical rear wing on Tuesday morning as the year’s first in-season test got underway at the Barcelona circuit.

Test driver Alex Lynn ventured out on Tuesday morning with an additional rear wing mounted to the existing wing on his FW38.

The design, though, is not legal under F1’s current regulations.

Williams confirmed to F1i.com that they were running it in order “to gain a better understanding of the car aero balance over a lap.”

Meanwhile Jenson Button, who was trialing minor updates to his Honda engine, was quickest on Tuesday morning, 0.010s up on Sebastian Vettel.

The McLaren driver, however, was using the super-soft tyres while the Ferrari driver put in his best time on the softs.

Nico Rosberg, who spent his 54 laps on the medium tyres, was third ahead of Lynn, Daniel Ricciardo and Manor’s Pascal Wehrlein.
