Daytona Prototype International

Restrictions at the front of the bodywork would also prohibit manufacturers from styling the outer regions of the nose, the area traditionally reserved for dive planes on a prototype.

[3] On 1 October 2015, IMSA confirmed the release of engine and bodywork guidelines, and announced the name of the then unnamed class - Daytona Prototype International.

Raffauf also stated that manufacturers would be allowed to make changes to the appearance of the bodywork or even debut new engines and/or branding over that period, subjected to approval and homologation by IMSA.

[9] Initially, it was planned that the DPi cars, outfitted with the standard LMP2 bodywork, would be eligible for Le Mans in LMP2, via ACO’s Balance of Performance process, to be controlled via the ECU.

However, following changes to the regulations by IMSA, which saw the spec Cosworth ECU, as well as other data logging systems removed, the ACO President Pierre Fillon voiced his displeasure on the DPi platform, which eventually led to the cars becoming ineligible in LMP2 at Le Mans.
