Porsche showed few signs of letting things slip over the winter as it topped all three sessions of the first day of collective pre-season testing ahead of the new FIA World Endurance Championship season.
The two-day WEC Prologue at Paul Ricard kicked off on Friday with defending champions Porsche setting the pace in the morning, afternoon and evening running as the updated 919 Hybrid stretched its legs.
Neel Jani ultimately set the fastest time of the day, recording a best lap of 1:37.487 in the evening session to finish eight-tenths of a second clear of Toyota's Kazuki Nakajima at the checkered flag.
Toyota enjoyed a strong first day of running with the new TS050 Hybrid, but the same could not be said of Audi as it suffered a number of issues on the new R18 car.
Andre Lotterer was sidelined by an issue in the evening session that brought Audi's day to an early end, following on from a mechanical problem in the afternoon.
British team Strakka Racing set the pace in LMP2 as Jonny Kane posted a best time of 1:46.976 in the afternoon session, while the new Manor WEC team made its public on-track debut.
The new Ferrari 488 GTE enjoyed a strong debut for AF Corse on Friday as Gianmaria Bruni and James Calado led the way in GTE Pro, while Larbre Competition set the pace in GTE Am with its Chevrolet Corvette.
Teams will be afforded another two sessions of running on Saturday at Paul Ricard as the Prologue comes to a close.
