The Porsche Mobil1 Supercup grid will be boosted by the addition of two star guest entries for round six of the season at Spa-Francorchamps.
Multiple World Rally Championship champion Sebastien Loeb will run in the livery of his eponymous team, while American TV star and part-time racer Patrick Dempsey will be entered via Porsche AG in the colours of his LeMans 24 Hours challenger.
Both drivers may well be able to spring a surprise; Loeb has previous Supercup experience from outings in the category in 2013, whilst Dempsey finished second in the GTE Am division at the Circuit de la Sarthe this year.
