In 2017, the European Le Mans Series presents three different categories: LMP2, LMP3, and LMGTE; Dallara is one of the four manufacturers chosen by FIA and ACO to provide the new chassis for the next-generation LMP2 prototypes class. This category, just below the top LMP1 class of the FIA World Endurance Championship, is a key part of the “Endurance" family which allows teams, as well as drivers, to gradually progress to higher levels. The "Le Mans Prototype 2" (LMP2) class is run exclusively by independent teams of constructors and engine suppliers.
The Dallara P217 is a new generation LMP2 featuring a carbon-fibre chassis, a raised nose and on the sides it has oval air front brake. The front suspensions are push rod with torsion bars, and the rear suspension is push rod with springs. The regulation engine is the naturally-aspired Gibson V8 with 4.200 cc and 600 bhp. Category rules demand a minimum weight of 930 kg. For several years, the dynamic air intake for the engine has been on the cockpit roof. There is a sequential X-Trac gearbox and the wheels are made in magnesium to save weight, and there are carbon disc brakes and pads.
