22-Hour Update: Total 24 Hours of Spa still impossible to call in closing stages

The winner of this year's Total 24 Hours of Spa remained impossible to call with just 120 minutes of racing left on the clock.

Audi Sport machinery was one-two shortly before the 22-hour mark, with the #66 Attempto car of Frederic Vervisch running just 1.6 seconds clear of Dorian Boccolacci's #25 Sainteloc entry.

The #66 held a lead of almost 90 seconds at one stage after making the correct decision to switch to wet tyres just as heavy rain arrived at the Ardennes venue. This buffer was wiped out by a safety car, which was deployed when #33 Belgian Audi Club Team driver Benjamin Goethe hit the barriers at Raidillon.

The #66 had already made its scheduled stop and, with the #25 able to pit under neutralised conditions, Boccolacci emerged ahead of Vervisch. The lead changed shortly after the safety car period ended, with the Attempto driver making a simple pass on his Sainteloc rival at Blanchimont.

Vervisch stopped again just shy of the hour and was relieved by Patric Niederhauser, who dropped to sixth. This put Boccolacci back in front, chased by the #51 AF Corse Ferrari, while the #98 ROWE Porsche ran third in the hands of Nick Tandy. One from this quartet now looks certain to take overall victory. 

The #72 SMP Ferrari had also looked to be a factor during the 22nd hour but spun into the barriers at Speakers Corner while battling with Patrick Pilet (#12 GPX Porsche). The #4 Mercedes-AMG Team HRT will take a 10-second time penalty at its next stop for causing a collision, effectively ending this crew's hopes as well.

The #77 Barwell Lamborghini leads Pro-Am but is being closed down by the #93 Sky Tempesta Ferrari in a battle that seems set to continue until the chequered flag. In contrast, the Silver Cup looks to have been decided in favour of the #5 HRT Mercedes-AMG, which is circulating two laps clear of its closest rival. As the sole remaining Am Cup runner, French squad CMR has wrapped up victory by completing a sufficient percentage of the race with its #108 Bentley.
