765LT customers who plan to race more often can order a race brake upgrade that includes the McLaren Senna's carbon-ceramic discs and custom LT brake pads. The improved brake discs are around 60% stronger than conventional carbon ceramic discs and have four times the thermal conductivity - and thus better thermal management - and thus reduce brake fading and wear.
A new, ultra-light 765-spoke forged alloy wheel has been developed for the 10LT. Together with wheel bolts made of titanium and tailor-made Pirelli P Zero ™ Trofeo R tires, the wheels - which are standard equipment - allow a total weight saving of 22 kg compared to the standard wheel and the standard tires of the 720S, which further improves the dynamic performance.
The Pirelli tires developed for the 765LT play an important role both for the ultimate grip and for the steering feel. McLaren and Pirelli's engineers worked closely together to ensure that the tailored tread pattern and construction of the tires increased the feeling of reaching the driver's fingertips. They also work in conjunction with the revised chassis dynamics and increased performance to enable the fastest lap times of all McLaren Super Series vehicles.
LT performance and performance brought to another level
The performance of the 765LT exceeds the expectations that its appearance already promises. The engineering philosophy behind the car has its roots in the very first LT, the McLaren F1 GTR 'Longtail' racing car. In the 765LT, expectations go far beyond the references that were developed with the earlier street-legal models of today.
The new 765LT is the most powerful and responsive street-legal McLaren LT to date. A 4,0-liter V8 McLaren M840T engine with double turbo - which has a flat-lying crankshaft and dry sump lubrication as well as a twin-scroll turbocharger with an extremely low flywheel mass and electronically controlled wastegates - has LT-specific forged aluminum pistons, a three-layer cylinder head gasket that is inserted in the McLaren Senna is used, and highly efficient, carbon-coated rocker arms in the valve train. An additional fuel pump and redesigned oil pump optimize flow, and a newly calibrated engine management system controls the increased power, with torque delivery and throttle response tailored for maximum driver involvement. The peak power is 765 hp at 7.500 rpm and the maximum torque 800 Nm at 5.500 rpm.
The transmission ratio is optimized for acceleration and offers practically instant response to accelerator pedal actuation and up to 15% faster response in the transmission than the 720S, which is itself a remarkable vehicle in this regard. The extraordinary performance of the 765LT is summarized by its benchmark acceleration values: 0-100km / h in 2,8 seconds and 0-200km / h in 7,2 seconds.
Stiffer engine mounts are used not only to achieve the dynamic performance goals, but also to increase the physical and emotional connection with the V8 powertrain by transmitting and emitting the low-frequency engine noise into the cabin. Every speed change is amplified, not only for the ears of the occupants, but also as a feeling through the seats, as low-frequency noises are both audible and palpable.
