DragonSpeed topped the timesheets on Friday during free practice, but Lapierre couldn’t improve on Beche’s impressive marker.
Row two of Sunday’s grid will feature the Greaves Motorsport Ligier-Nissan JSP2 which qualified third – albeit 1.3 seconds off the pace – with a 1:48.420s lap set by French driver Nathanael Berthon.
Berthon will start alongside the SMP Racing BR01-Nissan of Stefano Coletti, who edged out Andrea Pizzitola in the Algarve Pro Racing Ligier-Nissan by eight hundredths of a second.
Completing row three is the first of the open cockpit LMP2 cars, entered by Irish squad Murphy Prototypes.

Row two of the class grid sees Panis Barthez Competition’s Simon Gachet (1:54.817s) line up next to points leader Alex Brundle in the United Autosports entry (1:55.238s), with 360 Racing and M.Racing YMR behind.

In a close standoff with Alessandro Pier Guidi’s AT Racing Ferrari, Turner submitted a 1:56.285s lap to seal the top spot on the class grid.
Pier Guidi followed in second with a 1:56.483s effort, but in falling short he and team-mates Alex Talkanitsa Sr and Jr drop behind AMR in the standings on countback. Both teams will start Sunday’s race on 48 points.
