ENTRY LIST: Rolex 24

No major changes have been made since the Roar Before the 24, which, for the first time, was a mandatory test for all teams taking part in the twice-around-the-clock Florida endurance classic.

Up front, all eyes will be on the new DPi and LMP2 cars, with manufacturer involvement from Cadillac, Mazda and Nissan.

Wayne Taylor Racing and Action Express will both field Cadillac DPi-V.Rs, joined by the two factory Mazda RT24-Ps and pair of customer Tequila Patron ESM Nissan Onroak DPis.

Gibson-powered LMP2 entries, meanwhile will be run by Rebellion Racing (Oreca 07), PR1/Mathaisen Motorsports (Ligier JS P217), Visit Florida Racing (Riley Mk. 30) as well as DragonSpeed, which topped the time charts at the Roar with its brand-new Oreca-Gibson.

The only notable change on the driver front in the P class with Brendon Hartley listed in both ESM Nissans, after having originally been announced for the No. 22 entry only.

The GTLM class will feature a heavyweight battle between Corvette, Ferrari, Porsche, BMW and Ford, which fields four Ford GTs for the first time since its class victory at the 24 Hours of Le Mans last year.

Porsche, meanwhile, will give its mid-engined 911 RSR its competition debut, with the CORE autosport-run entries, now running under the globally unified Porsche GT Team banner.
