Porsche 1-2 in opening Silverstone practice
Timo Bernhard led the way in the damp 90-minute session, reeling off a best lap of 1:432.182 in the No. 1 car.
Bernhard’s time was 0.812 seconds quicker than the sister No. 2 Porsche in second.
The No. 5 Toyota TS050 Hybrid was third quickest overall and in LMP1, thanks to a 1:43.765 lap. The car, however, slowed on the final moments of the session with a suspected issue.
The No. 8 Audi R18 and No. 6 Toyota completed the top-five in the relatively incident-free session, despite less-than-ideal conditions.
G-Drive Racing was quickest in LMP2, with Rene Rast reeling off a 1:50.428 in his No. 26 Oreca 05 Nissan.
The No. 35 Baxi DC Racing Oreca Nissan and No. 43 RGR Sport by Morand Ligier JS P2 Nissan completed the top-three in class.
Ferrari led the way in both GTE-Pro and GTE-Am, with AF Corse’s new Ferrari 488 GTE topping the time charts with a 2:01.067 lap by the No. 51 car.
AF Corse’s previous-generation No. 83 Ferrari 458 Italia of Rui Aguas, meanwhile, led GTE-Am.
Free Practice 2 gets underway at 4:30 p.m. local time.
