The FIA World Endurance Championship has grown to 30 cars for the second round of the season, the WEC Six Hours of Spa, on May 4-6.

The provisional entry list, released after the season-opener at Silverstone, sees the addition of the third Toyota TS050 Hybrid and two extra LMP2 cars.

The LMP1 class increases to six cars with the addition of the No. 9 Toyota, driven by Stephane Sarrazin, Nicolas Lapierre and Yuji Kunimoto, which will run at Spa and the 24 Hours of Le Mans.

This is in addition to the two full-season cars each from Porsche and Toyota, as well as the ByKolles ENSO CLM P1/01 NISMO.

James Rossiter and Dominik Kraihamer are once again listed alongside James Webb in the ByKolles car.

LMP2 continues to be the largest class, with two additional entries bringing the total up to 11.

Tockwith Motorsports becomes the first team to enter the Ligier JS P217 Gibson in the series, while Signatech Alpine Matmut will enter a second Alpine A470 Gibson-badged Oreca 07 Gibson.

Reigning LMP1 drivers’ champion Romain Dumas will replace Lapierre in the No. 36 Alpine.

The two GTE classes remain unchanged from Silverstone, with two cars apiece from Porsche GT Team, Ford Chip Ganassi Racing, Aston Martin Racing and AF Corse making up the eight-car GTE-Pro field.

Spirit of Race and Clearwater Racing both continue to enter a Ferrari 488 GTE in GTE-Am, while a Porsche 911 RSR each from Dempsey-Proton Racing and Gulf Racing, as well as the Aston Martin, complete the five-car class.

The WEC Six Hours of Spa is set for May 6.
