The highest levels of driver engagement
Lighter, more powerful and with even higher levels of performance on both road and track, the McLaren 765LT is today revealed as the latest and the most dynamically advanced and engaging LT model ever from McLaren Automotive.
The 765LT opens a new chapter in the ‘Longtail’ story that began with the McLaren F1 GTR race car in the 1990s and since 2015 has seen road-legal LT models introduced. The new car elevates to new levels the attributes that underpin every LT: driver engagement, track-focused dynamics, minimised weight, optimised aerodynamics and increased power are all amplified particularly the first two. The LT promise of being limited to the few is also fulfilled, with just 765 individually numbered cars available globally for customer order.
Advanced carbon fibre technologies and bespoke carbon fibre LT body panels and aerodynamic features are key to an 80kg (DIN) weight reduction over the 720S. Together with power of 765PS and torque of 800Nm from the 4.0-litre, twin-turbocharged McLaren V8 engine, transmission gearing optimised for scintillating in-gear acceleration and LT-specific suspension springs and dampers, this is the basis for the wholly immersive driving experience the new 765LT delivers.
The highest levels of driver engagement
The dynamic ability and precision of the 765LT on both road and track is simply outstanding, taking circuit performance to new heights and making every road drive a joy. Driver satisfaction is guaranteed by extraordinary levels of engagement between driver and car, the result of absolute focus on delivering unparalleled feedback and connection.
The renowned McLaren Super Series chassis dynamics have been further enhanced in the 765LT, to provide the ‘communication and feel’ that allow a driver to fully exploit the extreme performance of the car when appropriate, but also enjoy it at lower speeds. The steering of the 765LT retains distinguished electro-hydraulic assistance but has been further honed with a quicker ratio and a stiffer torsion bar for even purer driver feedback. The state-of-the-art, linked-hydraulic Proactive Chassis Control II suspension introduced with the 720S features updates to both software and hardware to meet the dynamic requirements of the 765LT; advances made during the development of the McLaren Senna and Speedtail have seen the suspension system algorithms revised to ensure even greater precision and control.
The aerodynamic performance of the 765LT is key to the abilities of the car on track, but also influences higher-speed road driving behaviours. The extended front splitter and elongated active rear MEDIA wing work in conjunction with the carbon fibre floor, unique door blades and the extended rear diffuser to deliver aerodynamic downforce 25% greater than that available to a 720S driver, adding a further dimension to already excellent aerodynamic performance.
The new, high-set static position of the ‘Longtail’ active rear wing aids powertrain cooling by drawing hot air out of the engine bay as well as increasing downforce, while the airbrake functionality reduces dive sensitivity under heavy braking. This allows the front springs to be softer than would be required if they were solely responsible for maintaining the front ride height, which in turn enables improved front axle compliance characteristics, to the benefit on-road driving.
Gearbox and suspension characteristics are adjustable through Comfort, Sport and Track modes settings using the Powertran and Handling settings within McLaren’s trademark Active Dynamics Panel. A new ‘limit downshift’ transmission function is introduced on the 765LT. Previously, a downshift would be refused by McLaren’s 7-speed Sequential Shift Gearbox if the resulting change would over-rev the engine; on the new LT, the transmission software will acknowledge the downshift request and change gears accordingly when the engine speed and road speed can be harmonised. This feature is designed to give a driver greater freedom on when to select gear changes as well as creating audible drama inside and outside the car by allowing the engine rev to ‘bounce’ momentarily on the rev-limiter before the next gear engages.
LT power and performance taken to another level
The performance of the 765LT more than lives up to the expectations set by its looks. The engineering philosophies that underpin the car have their roots in the first-ever LT, the MCLaren F1 GTR ‘Longtail’ race car, but push onwards in the 765LT well beyond the credentials developed with the previous road legal modern-day models.
The new 765LT is the most powerful and responsive road-legal McLaren LT to date. A 4.0-litre twin turbocharged V8 McLaren M840T engine which has a flat-plane crankshaft and dry sump lubrication, together with ultra-low inertia twin-scroll turbochargers and electronically controlled wastegates features LT-specific forged aluminium pistons, a three-layer head gasket used in the McLaren Senna and ultra-efficient, carbon-coated followers in the valve train. An additional fuel pump and revised oil pump optimise flows and a recalibrated engine management system controls the increased power, with torque delivery and throttle response tuned for maximum driver engagement. Peak power is 765PS (755bhp) at 7,500rpm and maximum torque 800Nm (590 lb ft) at 5,500rpm.
Transmission gearing is optimised for acceleration, delivering virtually instant response to throttle MEDIA inputs and in-gear acceleration up to 15% quicker than the class-benchmark 720S, itself a remarkable car in this respect. The extraordinary performance of the 765LT is summarised by its benchmark acceleration statistics: 0-100km/h (62mph) in 2.8 seconds (0-60 mph in 2.7 seconds) and 0-200km/h (124mph) in 7.2 seconds
Absolute focus on reducing weight
The lightweight design and engineering philosophy that McLaren pursues in all its cars is even more important in an LT model. Reducing vehicle weight lessens inertia while amplifying acceleration, braking and steering inputs, a recipe that creates a car that reacts immediately to every ‘request’ from a driver’s hands and feet. Driven by a determination to minimise weight at every opportunity, McLaren engineers achieved an 80kg (DIN) saving over the superlight 720S coupé, itself a leader in power-to weight comparison with direct competitors. At 622PS per tonne at lightest dry weight, the 765LT redefines the class, bettering rivals by more than 50PS per tonne.
The reduction in weight has been achieved through extensive use of carbon fibre a material in MEDIA which McLaren has renowned expertise in body panels and components, as well as by optimisation of powertrain and chassis parts and deletion of comfort and convenience features (although these can in most cases be specified if preferred, at no additional cost).
For the first time on a modern-day McLaren LT, the thickness of the side window glass has been reduced. The windscreen is also thinner, and the glazed C-pillars and rear screen are formed from lightweight, motorsport-style polycarbonate. The upper sections of the dihedral doors feature lightweight carbon fibre panels. The 765LT also features a full-titanium exhaust system, which at just 10.9kg is 40% lighter than a comparable steel system, 3.8kg less than the exhaust of a 720S and even more weight-efficient than an Inconel exhaust.
Adopting every weight-saving measure available when specifying a 765LT results in a lightest dry weight of just 1,229kg. To reach this level, customers will need to include options such as the SuperLightweight Carbon Fibre Racing Seats. Developed for the McLaren Senna and crafted in carbon fibre, the seats are constructed using an innovative double-skin shell technology that reduces weight by one-third in comparison with the same seat shell manufactured using conventional carbon fibre processes. Each seat shell weighs just 3.35kg.
Aerodynamically sculpted in carbon fibre
As well as being the most powerful McLaren LT ever, the new 765LT is physically the most extreme. The front splitter sits closer to the ground because of a 5mm reduction in front ride height that increases vehicle rake to create more front downforce. The nose of the car has been lengthened by 48mm, both the front bumper and front splitter moving further firward. The new ‘Longtail’ active rear wing stretches rearwards by an additional 9mm, the two changes together adding 57mm to the overall length of the car.
The design of the rear of the 765LT is just as focused. Slightly longer, as befits an LT, the bodywork has less physical volume, increasing heat evacuation from the engine bay and reducing air pressure within the wheel arches. The reduction in pressure is achieved by pushing the rear bumper even closer into the MEDIA engineering hard points, exposing the rear tyres.
