A total of 39 cars will line up for the inaugural Road to Le Mans support race on the weekend of the 24 Hours of Le Mans next month (June 18).
The one hour race is part of the new Michelin GT3 Le Mans Cup, and will also feature a 22-strong grid of invited LMP3 entries.
Ligier JSP3-Nissans dominate the entry, with 14 coming from the European Le Mans Series. There is also a Ginetta-Nissan listed for Laurence Tomlinson, and an ADESS 03-Nissan for Finnish outfit PS Racing Ltd.
There is a strong French presence in the LMP3 field, with Duqueiene Engineering and Graff Racing set to run three cars each.
ELMS championship leaders United Autosports will also field two Ligiers, including one for 1990 Le Mans winner Martin Brundle.
Also of note is the Racing Team Holland entry, featuring another Le Mans winner in Jan Lammers plus his team-mate Bernhard van Oranje-Nassau.
In GT3, eight different manufacturers are represented in a diverse 17 car field.
Aston Martin, Audi, Ferrari, McLaren, BMW, Mercedes, Lamborghini and Porsche are all listed, with both new and old GT3 machinery expected to take part.
Michelin GT3 Le Mans Cup points leader TF Sport has two Aston Martin V12 Vantages for Salih Yoluc/Euan Hankey and Andrew Jarman/Devon Modell. British interest is supplemented by single car entries for Barwell Motorsports (Lamborghini Huracan) and Tockwith Motorsports (Audi R8 LMS).
The BMW Z4 will make its return to GT3 competition with Luxembourg squad DKR Engineering, while three of the new Ferrari 488s are entered by AF Corse (x2) and FF Corse.
AF Corse is also preparing two older-spec Ferrari 458 Italias, with FIA World Endurance Championship star Rui Aguas slated to drive the #14 car.
Aguas is the only driver from the Road to Le Mans field who is also competing in the 24 Hours of Le Mans.
