McLaren 765LT

The McLaren 765LT, revealed in 2020, continued the storied 'Longtail' lineage that began with the legendary McLaren F1 GTR Longtail racing car of 1997. The 'LT' designation signifies McLaren's most focused, driver-oriented interpretation of their Super Series platform — a car where every engineering decision prioritizes reduced weight, increased downforce, and sharpened dynamic responses.

The 765LT is based on the already exceptional 720S but subjected to an obsessive weight-reduction program. McLaren's engineers saved 80 kg compared to the 720S through measures including carbon fiber body panels, thinner glass, a titanium exhaust system, lighter forged alloy wheels, a polycarbonate rear screen, and even the deletion of air conditioning and audio system as standard (both were available as no-cost options). The carbon fiber racing seats saved 18 kg alone. The result was a dry weight of 1,229 kg — astonishingly light for a twin-turbo V8 supercar with this level of performance.

The 4.0-litre twin-turbocharged M840T V8 engine was significantly upgraded, producing 755 hp at 7,500 rpm and 590 lb-ft of torque at 5,500 rpm — increases of 45 hp and 22 lb-ft over the 720S. Changes included forged aluminium pistons, a three-layer head gasket from the Senna, revised turbo compressor and turbine design, a new carbon fiber intake plenum, and the titanium exhaust system that saved weight while improving gas flow. The engine's soundtrack, particularly the crackling overrun, was considerably more dramatic than the 720S.

The seven-speed dual-clutch gearbox was recalibrated with faster shift times and more aggressive software mapping. In the most aggressive settings, the 765LT could dispatch upshifts in milliseconds, contributing to its devastating acceleration: 0-60 mph in 2.7 seconds, 0-124 mph (200 km/h) in 7.0 seconds, and a quarter mile in under 10 seconds.

Aerodynamically, the 765LT generated 25% more downforce than the 720S. The 'Longtail' extended rear bodywork, active rear wing, front splitter, floor-mounted carbon fiber diffuser, and elongated door blades worked together to produce significant aerodynamic load at high speeds while maintaining the 720S's impressively low drag coefficient.

The suspension was completely retuned with stiffer springs (front +13%, rear +37%), revised adaptive damper calibration, and a lower ride height. The Proactive Chassis Control II hydraulic suspension system — McLaren's interconnected adaptive damper technology — was recalibrated for a more aggressive baseline while retaining its remarkable ability to control body roll without anti-roll bars.

McLaren limited production to 765 units — matching the car's PS power figure. The 765LT sold out before deliveries began, and it was joined in 2021 by a 765LT Spider convertible variant. Both versions received near-universal critical acclaim, with many journalists ranking the 765LT as the finest McLaren road car of its era.
