The FIA is looking to operate the LM Hypercars and LMDh prototypes under the “same performance window,” ahead of its WEC debut later this year.

In a meeting in Geneva, the FIA World Motorsport Council approved the “general principles” that collaborates the upcoming top-tier class in WEC and the North-American endurance sports-car championship IMSA.

On Friday, they backed the makings of a convergence platform that will form the basis of the leading prototype classes in these two major endurance championships, which were announced in earlier in January this year.

Furthermore, the Le Mans Hypercar platform and newly revealed LMDh (Le Mans Daytona Hypercar) class are to set race together under a “single and unique” top category in the WEC.

The FIA also discussed how the platform will maintain the existing FIA WEC Technical Regulations, including the Le Mans Hypercar.

The LMDh cars will be based on a new chassis that will be common to both WEC and the IMSA WeatherTech SportsCar Championship top categories.

To add to this, they will be looking at establishing a ‘Balance of Performance’ through adjusting a framework highlighted by the WMSC release.

“Parameters such as power unit performance, aerodynamic characteristics and weight will be aligned for both the Le Mans Hypercars and the LMDh cars in order to ensure both will operate in the same performance window.”

They declared that LMDh and LMH cars will be matched when they converge in the WEC 2020-2021 season, commencing later this September.

There will be further details on the LMDh regulations announced at the Sebring IMSA and WEC double-header proceeding later this month.

The 2020-2021 calendar for WEC (announced last December) was also approved at Geneva:
