Overview

• Only five examples will be built to customer specification with deliveries scheduled for 2026, with some reports saying all five go to a single buyer and pricing undisclosed.
• The S1 LM replaces the T.50’s rear fan with a conventional high‑downforce package featuring a large splitter, twin rear wing and a full diffuser.
• Track‑focused hardware includes a stiffer suspension with revised geometry and a solid‑mounted V12 paired with a six‑speed manual gearbox.
• The road‑legal cabin retains a McLaren F1‑style three‑seat layout with a central driving position and scissor doors.
• Outlets report differing peak outputs for the 4.3‑liter naturally aspirated V12, citing figures of over 690 PS or over 700 PS.
