Key Facts

The 2021 season ran from May 14 to September 19 across five rounds.
It supported the European Le Mans Series (ELMS) at all events.
The series featured two classes: LMP3 and GT3.

Overview

The 2021 Michelin Le Mans Cup served as a key support series within the European Le Mans Series (ELMS) calendar, offering competitive endurance racing with a focus on driver development and prototype experience. Organized by the Automobile Club de l'Ouest (ACO), the same body behind the 24 Hours of Le Mans, the series provided a structured pathway for amateur and emerging professional drivers.

With a condensed five-round schedule, the 2021 season emphasized accessibility and close competition across two primary classes: LMP3 prototypes and GT3 sports cars. The championship attracted international teams and drivers aiming to gain experience on iconic circuits ahead of potential campaigns in higher-tier endurance events.

LMP3 cars featured in the prototype class, with models from Ligier, Ginetta, and ADESS complying with 2021 ACO regulations for performance balance.
GT3 entries included manufacturers like Porsche, Ferrari, and McLaren, all adhering to FIA GT3 technical standards and competing in the Cup’s GT class.
The season began on May 14 at Circuit Paul Ricard in Le Castellet, France, marking the traditional start of the European endurance season.
Each round consisted of two 55-minute races, promoting consistent performance and strategic tire management under Michelin’s single-supplier tire agreement.
Driver lineups required at least one bronze- or silver-rated driver per car, ensuring competitive balance and development opportunities for less experienced racers.

How It Works

The Michelin Le Mans Cup operates as a single-make tire series with regulated technical specifications across entries, ensuring close racing and cost control.

Endurance Format: Each event weekend included two races lasting 55 minutes, requiring mandatory pit stops and driver changes. This format simulated real-world endurance conditions and tested team coordination.
Class Structure: The series split competition into LMP3 and GT3 classes, each with separate point standings and podiums, allowing different car types to compete simultaneously.
Driver Ratings: The ACO’s driver categorization system was enforced, with LMP3 entries requiring at least one bronze- or silver-rated driver to promote accessibility.
Tire Regulations: All teams used Michelin tires exclusively, with each car limited to a set number of sets per weekend to manage costs and strategy.
Balance of Performance: The ACO implemented BoP adjustments for GT3 cars and performance weights for LMP3s to ensure equitable competition across manufacturers.
Scoring System: Points were awarded down to 20th place, with 25 points for a win, scaling down to 1 point, encouraging full-course participation and consistent finishes.
