Doonan: Current LMDh Cars Won’t Be “Obsolete” in 2030

IMSA President John Doonan indicated the current designs of LMDh manufacturers will not become “obsolete” under the rules that will be introduced in the WeatherTech SportsCar Championship and the FIA World Endurance Championship in 2030.
Doonan was speaking immediately after Friday’s ACO press conference, where the governing bodies of the world’s two largest sports car racing series fleshed out their vision for a unified set of regulations at the end of the decade.
Manufacturers will be permitted to use either its own bespoke chassis or a ‘spine’ from one of the four licensed chassis manufacturers that are currently available to LMDh competitors.
Those following the latter path can then choose between making their own hybrid system and a common solution produced to the same regulations.
Reacting to the news, Doonan said current LMDh competitors competing in either series would not need to develop a new car from scratch.
“I think one of the things we make sure of is that the investments that everyone have made do not become obsolete,” said Doonan.
“From an engine standpoint, obviously, my hope would be that they could carry those on. The same with much of what they developed from the spine standpoint.
“The four constructors, Dallara, Multimatic, Ligier and ORECA, have dedicated so much to their work with the manufacturers. None of those things do we want to become completely obsolete.
“Will there be updates to the cars based on the new regulations, or will others competing in the top category have to modify their strategy and develop a car to these regulations? Yes.
“The goal would be to make sure we don’t completely obsolete what people have today.”
When asked if LMDh manufacturers could simply modify its existing cars to race in 2030, Doonan replied: “That’s certainly one of the options.”
Doonan also clarified that the four existing LMDh constructors will continue to be the choices open to competitors in the 2030 rules.
FIA, ACO: 2030 Spines Could Be Unique to Each Manufacturer
Providing further insight into the new regulations, FIA chief technical and safety officer Xavier Mestelan-Pinon revealed speaking to selected media, including Sportscar365, that the 2030 spines may end up being unique to each manufacturer.
Currently, if two LMDh manufacturers are using the same chassis — for example, Alpine, Genesis and new-for-2027 WEC entrant Ford all use the ORECA spine, as well as Acura in the WeatherTech Championship — they cannot be tailored for each.
This will no longer be the case in 2030 under plans being worked on by the governing bodies, however.
“You can have some differentiation with the spine,” said Mestelan-Pinon. “Today, if you have an ORECA [spine], you cannot have any difference [to any other manufacturer using the same spine]. Here, you can have some difference.
“All the data needs to be refined. Everything we present here is just a guideline. Please now be patient while we work on it.”
ACO competition director Thierry Bouvet also said that the thinking behind introducing a prescribed underfloor and diffuser is “to be a little bit more constraining” in terms of the aerodynamic window, to facilitate greater variety on the car’s upper surfaces.
“The most important is to further the flexibility of the external design,” he said.
Regarding the provision for manufacturers to continue creating its own hybrid systems, as Toyota, Ferrari and Peugeot currently do, Bouvet said that the rules will be created in such a way that no advantage will be gained from this route.
“Manufacturers will be able to do their own system, but it will be the same technical specification, to avoid what you are describing,” he said.
When asked by Sportscar365 if that meant a manufacturer following a standard design with its own components, Bouvet responded: “Maybe not the design, but the same output.”
