Harry Tincknell put the No. 007 Aston Martin Valkyrie atop the timesheets in Free Practice 3 for the 6 Hours of Fuji, marking the first time the British marque’s V12-powered Hypercar has led an official FIA World Endurance Championship session.
Tincknell’s best effort of 1:29.492 was 0.024 seconds faster than the No. 38 Cadillac V-Series.R in the hands of Earl Bamber.
In the process, the Brit carried through Aston Martin’s strong form from Friday running, during which the Valkyries came in third in both Free Practice sessions.
Saturday, however, marked the first time the British brand topped an official session overall since the Valkyrie made its WEC debut in Qatar earlier this year.
Alex Lynn picked up third in the No. 12 Cadillac, while the second Aston Martin slotted into fourth with Marco Sorensen at the wheel.
The top five was rounded out by the No. 94 Peugeot 9X8 of Stoffel Vandoorne ahead of the No. 20 BMW M Hybrid V8 driven by Sheldon van der Linde and the No. 35 Alpine A424 in the hands of Charles Milesi.
The second Peugeot, driven by Mikkel Jensen, took eighth, with the No. 8 Toyota GR010 Hybrid and No. 83 Ferrari 499P completing the top ten.
Aston Martin also led the way in the LMGT3 category, courtesy of a 1:40.800 set by Zach Robichon aboard the No. 27 Heart of Racing Team Vantage GT3 Evo.
The Canadian’s best lap was just 0.038 seconds faster than James Cottingham aboard the No. 59 United Autosports McLaren 720S GT3 Evo.
Rui Andrade went third in the No. 81 TF Sport Chevrolet Corvette Z06 GT3.R, followed by the second United McLaren with Sean Gelael at the wheel.
The 60-minute session ran largely without interruption, with the exception of a Full Course Yellow that was triggered when Ben Tuck’s No. 77 Proton Competition Ford Mustang GT3 spilled oil on track and stopped at Turn 1.
Qualifying at Fuji is scheduled to begin at 2:20 p.m. local time (1:10 a.m. EST).
