McLaren launches their most powerful convertible yet.

Very few cars in McLaren history have carried the Longtail badge, and that makes the launch of a new LT model a very special moment.

Renowned worldwide for the exclusive, luxury, high-performance supercars on which it has built its reputation over the past decade, McLaren Automotive today reveals another landmark model: the 765LT Spider.

Complementing the 765LT ‘Longtail’ coupe unveiled last year – all of which are sold – the new Spider is McLaren’s most powerful-ever convertible supercar and brings highest-ever levels of driver engagement to the McLaren LT experience. Engineered in addition with the other core attributes intrinsic to any McLaren Longtail – minimised weight, track-focused dynamics and optimised aerodynamics – the 765LT Spider has all of the class-leading abilities of the coupe and also meets the LT demand for exclusivity: just 765 cars will be available globally for customer order.

Carrying over the coupe’s dynamic and aerodynamic DNA with no structural compromise and only a minimal 49kg weight increase – primarily from the retractable hard top and accompanying operating mechanism – the 765LT Spider weighs in at just 1,388kg (DIN weight), which is 80kg lighter than a 720S Spider and circa 100kg lighter than its closest comparable competitor.

The electrically operated, one-piece carbon fibre Retractable Hard Top (RHT) enables open-top motoring in just 11 seconds and operates at speeds of up to 50km/h, bringing the dramatic soundtrack of the quad-exit titanium exhaust system into the cabin to take driver engagement into another dimension.

The immense performance and dynamic prowess of the new Spider – already proven in the 765LT coupe – are enhanced by three compelling factors: the stability of its MonoCage II-S structure, the game-changing design of its one-piece Retractable Hard Top roof, and the ongoing determination of McLaren engineers to pursue the company’s philosophy of super-lightweight engineering.

The Spider version of the carbon fibre MonoCage II – designated MonoCage II-S – was developed alongside the coupe monocoque and shares most of its structural elements, including the windscreen surround. Such is the strength and stiffness of the structure that no additional bracing is required over the coupe – another weight-optimising factor. At the rear of the car, carbon fibre structural supports are fully bonded into the chassis to provide rollover protection.

The convertible roof design plays an integral role in the structure, featuring a carbon fibre frame within the Retractable Hard Top panel and creating a full carbon fibre shell when closed. There are also additional comfort benefits for occupants – because it is a single-piece panel with no central seal, headroom is improved, while the extended length of the roof panel allows the tops of the A-pillars to be further forward, enhancing the sense of space and easing ingress and egress.

Performance

Performance is ferocious, the 4.0-litre twin-turbocharged V8 engine producing 765PS – giving the 765LT Spider a best-in-class power-to-weight ratio of 598PS-per-tonne at lightest dry weight – and 800Nm of torque. Transmission gear ratios have been revised for even greater engagement and performance; in-gear acceleration is 15% quicker than a 720S Spider, helping the new Longtail to achieve the fastest lap times ever posted by a convertible LT model.

The 0-100km/h time often seen as a benchmark figure is 2.8 seconds (0-60mph is 2.7 seconds), with 0-200km/h (124mph) taking 7.2 seconds. The new LT Spider takes 10.0 seconds to cover 400m (¼ mile) from standstill and the car’s maximum speed is 330km/h (205mph).
