A defining feature of Le Mans and endurance racing is that several different classes race on the same track at the same time, each with its own winner. Faster prototypes must constantly pick their way through slower GT traffic, which is a core skill of the discipline.
The current structure is broadly:
- Hypercar — the top prototype class, fighting for the overall win. Purpose-built, hybrid-era machines from manufacturers such as Ferrari, Toyota, Porsche, Cadillac and others, built to two convergent rulebooks (LMH and LMDh) balanced to race together.
- LMP2 — a spec prototype class using a common chassis and engine, quick but a clear step below Hypercar, popular with independent teams.
- GT (currently LMGT3) — production-based grand-touring cars from brands like Ferrari, Porsche, Aston Martin, BMW and Corvette, often shared by professional and amateur drivers.
Class structures evolve over the years (LMP1 and GTE were recent predecessors), but the principle of multi-class racing — several categories, one race — is constant. Learn the event itself in What is the 24 Hours of Le Mans?.
