In the first wave of an expected overhaul of the second-tier prototype platform, the FIA has confirmed that the LMP2 class will feature a spec engine beginning in 2017.

As revealed by Sportscar365 last month, the FIA and ACO proposed radical new regulations to the cost-capped prototype class, including a limit of four chassis constructors and a single engine supplier for the FIA World Endurance Championship, European and Asian Le Mans Series.

Confirmation came during today’s FIA World Motor Sport Council meeting in Geneva, with the spec engine part of the “goal to universalize” the category.

Manufacturers are due to meet with the FIA and ACO next week in Paul Ricard to finalize the remainder of the regulations, including the tender process for the single engine provider as well as the expected four official constructors.

Despite the FIA’s wording, it’s expected the TUDOR United SportsCar Championship will continue with open engine rules, although their cars, which may also feature brand-specific bodywork, would only be eligible for the 24 Hours of Le Mans.

The proposal has received mixed reviews from manufacturers in the industry.
