An updated entry list has been released for this weekend’s Roar Before the Rolex 24 pre-season test at Daytona International Speedway.

While featuring an unchanged 47-car entry for the mandatory three-day test, a number of drivers have been confirmed as the initial release omitted drivers names.

No major additions have been made to DPi beyond Wednesday’s confirmation from Mazda Team Joest of its driver lineup, including new recruits Olivier Pla and Timo Bernhard, as first revealed by Sportscar365 last month.

LMP2 sees Kyle Masson and father Dr. Robert line up alongside Cameron Cassels and the previously confirmed Kris Wright in the No. 38 Performance Tech Motorsports Oreca 07 Gibson.

The remainder of PR1/Mathiasen Motorsports’ lineup, meanwhile, remains to-be-announced, with DragonSpeed’s drivers, which have mostly been confirmed, not listed on the entry list.

Davide Rigon is set to join Miguel Molina in the No. 62 Risi Competizione Ferrari 488 GTE, with Laurens Vanthoor set to miss the test due to the expected arrival of his and his wife’s first child.

There are numerous driver confirmations in GTD, including Kang Ling in the No. 11 Grasser Racing Team Lamborghini Huracan GT3 Evo and Chico Longo, Victor Franzoni and Marcos Gomes in Via Italia Racing’s Ferrari 488 GT3.

Luca Stolz and Felipe Fraga will complete Mercedes-AMG Team Riley’s lineup, while Steve Dunn, Brandon Gdovic and Don Yount have been added to PPM’s Lamborghini in addition to Sunoco Whelen Challenge winner Linus Lundqvist.

P1 Motorsports, which has yet to formally announce its full-season lineup, meanwhile, has Mercedes-AMG factory driver Maxi Buhk listed alongside Dominik Bauman, Fabian Schiller and team owner/driver JC Perez in the No. 71 Mercedes-AMG GT3.

Porsche factory driver Sven Mueller, as well as Klaus Bachler and Juergen Haerimg are set to drive NGT Motorsports’ new Porsche 911 GT3R, with factory aces Dirk Werner and Matteo Cairoli joining Tim Pappas in Black Swan’s Porsche.

Additional names are set to be confirmed in the coming days.

Testing action gets underway on Friday, with a total of seven sessions on tap for DPi, GTLM and LMP2, and five for GTD competitors, which have a reduced two-day schedule.
