McLaren 600LT Coupe
The McLaren 600LT carried the legendary Longtail designation into the Sports Series range, applying the same philosophy that had made the 675LT and the original F1 GTR Longtail so revered: more power, less weight, more aerodynamic downforce. The result was arguably the finest driver's car McLaren had produced in the Sports Series.
The twin-turbo 3.8-litre V8 was upgraded to produce 592 horsepower and 457 lb-ft of torque, improvements achieved through revised camshaft profiles, enhanced cooling, and a freer-flowing exhaust system. The most dramatic visual change was the top-exit exhaust, which vented through the rear deck above the engine — a feature that produced an intoxicating bark on downshifts and an otherworldly soundtrack at full throttle.
Weight reduction was comprehensive and effective. The roof panel was carbon fiber, the seats were lightweight carbon racing buckets, the air conditioning was deleted as standard (available as a no-cost option), and the sound insulation was reduced. The result was a kerb weight of 1,247 kg, approximately 100 kg lighter than the 570S upon which it was based.
Aerodynamic modifications extended the body length by 74mm (hence 'Longtail'), with a redesigned front splitter, extended side sills, fixed rear wing, and enlarged rear diffuser generating 100 kg more downforce than the 570S. These changes had a transformative effect on high-speed stability and cornering ability.
The chassis received stiffer springs (a 14% increase at the front, 10% at the rear), recalibrated adaptive dampers, and a revised stability control system. Carbon ceramic brakes were standard, featuring upgraded pads and calipers from the Super Series range. The overall effect was of a car that felt notably sharper and more responsive than the already excellent 570S.
On circuit, the 600LT was devastating. It could lap many tracks faster than the 675LT, despite having less power, thanks to its lower weight and improved aerodynamics. Professional drivers consistently praised its balance, feedback, and the confidence it inspired at the limit.
Production was limited to approximately 1,588 coupes (plus additional Spiders), making the 600LT meaningfully rarer than the 570S. The car was offered in both coupe and Spider forms, with the coupe being slightly lighter and marginally more rigid. Values have held well, reflecting the 600LT's reputation as one of the finest McLarens of the modern era.
Check for any track use history, as many 600LTs have been used enthusiastically. Carbon ceramic brakes should be inspected for cracks, especially if track use is documented. The top-exit exhaust can discolor the rear deck paint; check for evidence of heat damage. Carbon fiber racing seats may show wear. Dual-clutch gearbox should shift smoothly in all modes. Full McLaren dealer service history is essential. The lightweight components mean any replacement parts are expensive.
Production ran from 2018 to 2020 at Woking, with 1,588 coupes and additional Spider variants built. The 600LT was confirmed as a limited production model from the outset. Carbon fiber roof panel was standard on the coupe; the Spider used a retractable hard-top. The top-exit exhaust required significant engineering effort to manage heat and emissions.
