Pole position for this year's Spa 24 Hours appears to have been decided early after a torrential downpour soaked the circuit just 10 minutes into the first qualifying session.
The #2 Vitaphone Maserati of Miguel Ramos, Alex Muller, Pedro Lamy and Eric Van de Poele had just gone to the top of the time sheets on a damp track when the storm clouds hit. The car's 2m18.030s effort put it at the head of a team one-two-three, with the #33 Alessandro Pier Guidi/Stephane Lemeret/Carl Rosenblad/Vincent Vosse car and #1 Michael Bartels/Andrea Bertolini/Stephane Sarrazin/Alexandre Sarnes Negrao MC12 following.
The leading Chevrolet Corvette C6.R is the Sangari Team Brazil entry in fourth. The Enrique Bernoldi/Roberto Streit/Xavier Maassen car had been on pole earlier in the session and was on a lap that seemed set to put it ahead of the Maseratis when the rain forced it into the pits.
The Selleslagh Racing Corvette of Bert Longin, James Ruffier, Maxime Soulet and Oliver Gavin was fifth fastest, two seconds clear of the fastest new-generation GT1 car, the Ford GT of the Marc VDS Racing Team.
Quickest GT2 car, and ninth overall, is the AF Corse Ferrari 430 of Toni Vilander, Gianmaria Bruni, Jaime Melo and Luis Perez Companc on 2m25.232s. The #55 CRS Racing Ferrari is second, while the fastest Porsche 911 GT3 RS is the sole Trackspeed entry in third.
The #121 Matech Ford GT is provisionally on the G3 class pole for GT3-type machines, ahead of the only Aston Martin DBRS9, run by Barwell Motorsport.
The Phoenix Audi R8 LMS of Marcel Fassler, Henri Moser, Alexander Margaritis and Marc Besseng, which showed impressive pace in the practice sessions earlier today, tops the G2 class, with a 2m28.327s lap in 17th overall.
With all qualifying sessions scheduled to run tonight it seems unlikely that the track will dry in time for any improvements.
