Which car is it — 540C vs 570S vs 570GT vs 600LT
All four cars share the MonoCell II carbon-fibre monocoque, the M838T E 3.8L twin-turbo V8 architecture, the 7-speed Graziano SSG DCT and Woking assembly (per Wikipedia 'McLaren 570S', fetched 6 July 2026). The 540C is the entry model at 533 hp / 540 PS / 397 kW (Wikipedia, fetched, verbatim). The 570S is the standard Sports Series coupé at 562 hp / 570 PS / 419 kW. The 570GT is the softer, GT-configured sibling with a side-opening rear cargo hatch and softer suspension (Wikipedia, fetched). The 600LT is the top of the Sports Series line — extended body, top-exit exhaust, fixed rear wing, 600 PS / 592 hp / 441 kW and a claimed 96 kg lighter than the 570S (Wikipedia, fetched). Verify the specific model designation via the VIN, the McLaren Retailer build sheet and the ECU calibration — the mechanical bodyshell is broadly common between 540C and 570S, and misrepresentation between the two happens in the UK / EU trade.
