The entry list for the Total 24 Hours of Spa has been released during the official test day on Tuesday, with a total of 68 cars set to take part in the Belgian endurance classic.

The race serves as both the Blancpain GT Series centerpiece as well as the second round of the Intercontinental GT Challenge which gets back underway following an almost six-month break after the Liqui-Moly Bathurst 12 Hour.

ENTRY LIST: Total 24 Hours of Spa

A GT3 era record of 13 manufacturers are represented in the field while several cars will make their debut appearance in the race, including the Honda NSX GT3 and 2018-spec Bentley Continental GT3 and Nissan GT-R NISMO GT3.

Thirty cars are entered in the Pro Cup while 16 cars will compete for Pro-Am honors, and nine each in the Silver and Am Cups.

Defending race winners Christopher Haase and Markus Winkelhock return to Audi Sport Team Sainteloc and are joined by Frederic Vervisch in one of three factory-backed Audi R8 LMS GT3s in the field.

Blancpain GT Endurance Cup points leaders Alex Riberas, Christopher Mies and Dries Vanthoor are in one of the Audi Sport Team WRT entries although IGTC leaders Stuart Leonard, Robin Frijns and Vanthoor are all in separate WRT cars.

The best represented brand is Mercedes-AMG with 13 cars on the grid including six in the Pro Cup and the return of HTP Motorsport to the series.

The GT3 field is joined by four Group National cars including three Porsche 991 Cups for SpeedLover and Muehlner Motorsport as well as a Lamborghini Super Trofeo run by GDL Motorsport.

There are still several to-be-confirmed slots on the provisional list including ROWE Racing’s entire driving lineup for its pair of Pro Cup BMW M6 GT3s.
