Meanwhile, familiar names such a Bost, Michael Whitaker and Daniel Deusser also made the cut.
Spain’s sole representatives came in the form of Julio Arias and his mount Lennox Luis.
The jump off course gave plenty of room for tight turns and some galloping. Hot favourites Daniel Deusser, Pieter Devos, Simon Delestre and von Eckermann all had surprising poles down, so the win was there for the taking.
McAuley - third rider to go – really got stuck in and took some risks putting him into first place, which set the tone for the fifteen to follow.
Eighth rider and former European champion Bost was the one to knock McAuley off the top spot by shaving half a second off his time, and he remained on top right until the very end.
Meanwhile, Spain’s Arias had the last pole down, much to the disappointment of the home crowd.
There were plenty of challengers for the top spot, notably Belgian rider Bruynseels and Marcus Ehning, who ended up fourth, with only half a second splitting the top four.
With the series now nearing the halfway point, Guerdat is just clinging on to his top spot with 43 points. von Eckermann is only three points behind, and Staut finds himself jostling for his third place spot with McAuley just one point behind him in fourth place.
