Allowing two different rules package to race together has been key to the Hypercar boom. But there are growing calls for a single platform
The Hypercar/GTP category combining LMH and LMDh regulations leads the World Endurance Championship and IMSA SportsCar Championship. Recently, LMDh manufacturers have called for a change supported by ACO and FIA. Convergence between the two platforms seems likely by 2028.
Initial differences between LMH and LMDh led to a unified approach from WEC and IMSA in 2023. LMH focuses on in-house design, while LMDh emphasizes approved suppliers and standard components for cost efficiency. Technical details vary between the two platforms.
Debates arise over advantages like all-wheel drive activation speeds and aero flexibility for LMH, versus power curve management for LMDh with the rear axle hybrid system. Challenges also include weight management and reliability for LMH due to the additional drivetrain.
Arguments exist on both sides for convergence or maintaining the status quo. Ultimately, finding a balance between the two regulations will be crucial for the future of Hypercar/GTP racing.
