A total of 37 cars will contest the opening round of the 2018-19 World Endurance Championship at Spa next month.
Several new drivers have been confirmed on the official entry list, including former GP2 race winner Nathanael Berthon who will race with the DragonSpeed squad in LMP2.
The Frenchman, who has spent the past four seasons in the European Le Mans Series, will embark on his first full WEC campaign alongside Pastor Maldonado and Roberto Gonzalez.
Russian prospects Egor Orudzhev (22) and Matevos Isaakyan (19) have been listed alongside ex-Toyota factory driver Stephane Sarrazin in one of the two SMP Racing-entered BR1-AERs that will race for overall honours in LMP1.
The pair claimed the first-ever victory for the Dallara P217 LMP2 chassis in last year's ELMS 4 Hours of Paul Ricard, and also claimed victories in the Formula V8 3.5 series.
SMP Racing's lineup confirmation means Vitaly Petrov and Mikhail Aleshin – the Russian squad's two nominated drivers on the provisional entry list – will drive the same car.
The rest of the 10-car LMP1 field is unchanged, with Toyota's two TS050 Hybrids – one featuring two-time Formula 1 champion Fernando Alonso – present along with the expected efforts from Rebellion (x2), Manor CEFC TRSM (x2), DragonSpeed (x1) and ByKolles (x1).
A handful of driver lineups, most notably the two Manor-entered Ginettas and the ByKolles CLM-Nissan, have yet to be completed.
LMP2 involves eight runners, with six Orecas, one Dallara and a Ligier taking part.
Jackie Chan DC Racing's #37 car has the all-Malaysian lineup of Jazeman Jaafar, Weiron Tan and Afiq Ikhwan Yazid listed, meaning Nabil Jeffri, who was announced with the team last week, will take up reserve driver duties.
There are few surprised in GTE-Pro, which features two cars for each of the five manufacturers.
The pairs of entries from Aston Martin, Ford and BMW will field three-driver crews in preparation for June's Le Mans 24 Hours, while Porsche and Ferrari will stick with the traditional two-driver format.
Indy 500 winner Tony Kannan will join the Chip Ganassi Racing Ford squad for his first WEC six-hour race appearance.
In GTE-Am, Giorgio Roda and Khaled al Qubaisi have been announced in one of the two Dempsey-Proton Racing Porsches 911 RSRs.
The 6 Hours of Spa takes place on May 5th.
