Next weekend’s Six Hours of Spa-Francorchamps will feature a 28-car field, following the release of the entry list for the second round of the FIA World Endurance Championship.

Audi, as expected, will field a third R18 e-tron quattro for drivers Filipe Albuquerque and Marco Bonanomi as the German manufacturer, and the rest of the grid use the race as the final warmup to the 24 Hours of Le Mans in June.

ENTRY LIST: Six Hours of Spa-Francorchamps

Following continued tests at Paul Ricard this week, Rebellion Racing is set to debut its new Rebellion R-Ones, while the Lotus LMP1 team is again absent from the entry list.

LMP2 features a five-car grid, bolstered by the Jota Sport Zytek Z11SN Nissan for Harry Ticknell, Marc Gene and Simon Dolan, although both Millennium Racing Oreca 03 Nissans will again not be present due to delays in funding.

The new Strakka-Dome S103 Nissan will also skip the Spa round, as expected.

Six cars are set to do battle in GTE-Pro following the withdrawal of Ram Racing, with the only other change coming with a two-driver lineup in both Porsche Team Manthey Porsche 911 RSRs, as Nick Tandy and Richard Lietz will be on TUDOR United SportsCar Championship duty at Mazda Raceway Laguna Seca.

GTE-Am sees an eight-car entry, thanks to an additional AF Corse Ferrari F458 Italia for Peter Mann, Raffaele Gianmaria and Lorenzo Case, while Richie Stanaway fills in for Nicki Thiim in the Silverstone class-winning No. 95 Aston Martin. Thiim will be on ADAC GT Masters duty that weekend.

The Six Hours of Spa-Francorchamps is set for May 2-3.
