The McLaren 675LT Spider

The new 675LT Spider opens the most engaging and exhilarating McLaren Super Series model up to the elements.


The next chapter in the illustrious history of the iconic McLaren ‘Longtail’ has been unleashed, with confirmation of the new 675LT Spider. Only the second McLaren to ever wear the LT badge – after the sold-out 675LT Coupé – the 675LT Spider has been created in response to worldwide customer demand. This limited edition model, restricted to just 500 examples, mirrors the 675LT Coupé in its extensive use of lightweight components, enhanced aerodynamics, increased power, and track-focused dynamics. A retractable roof adds further excitement, making the new 675LT Spider the fastest, most focused and most exhilarating open-top McLaren ever. 

At the heart of the 675LT Spider is a carbon fibre MonoCell chassis, while its soul is a heavily revised 3.8-litre twin turbo V8, guaranteeing performance worthy of the LT – or ‘Longtail’ – name. The light, stiff and strong MonoCell ensures no further strengthening is needed, meaning the new 675LT Spider is only 40kg heavier than its Coupé sibling, all due to the retractable roof system. The engine, shared with the 675LT Coupé, features more efficient turbochargers, revised cylinder heads and exhaust manifolds, a new camshaft, lightweight connecting rods, and a faster-flowing fuel pump. In total, over 50 percent of the powertrain components are new, and the extensive modifications mean the twin-turbo V8 engine produces an incredible 675PS (666bhp) and 700Nm (516lb ft).

The results of all this power and torque are phenomenal. The 675LT Spider accelerates from 0-100kph (0-62mph) in the same scant 2.9 seconds as its sibling, while 200kph (124mph) is achieved in just 8.1 seconds, only two-tenths shy of the more aerodynamically optimised and lighter Coupé. The top speed is 326kph (203mph), while the two-piece retractable folding hardtop can be opened at speeds up to 30kph (19mph) for a new level of open-air exhilaration never before experienced in a McLaren Longtail. 



Staying true to the ‘Longtail’ ethos – established by the race-winning McLaren F1 GTR ‘Longtail’ in the late 1990s – the 675LT Spider has been developed with a focus on enhanced lightweight components and optimised aerodynamic performance. As with the 675LT Coupé, the dramatic changes start with the prominent front bumper, larger splitter and end plates, which increase downforce levels by causing the air flowing over the front of the car to work harder. At the rear, the aerodynamics are balanced and optimised by the ‘Longtail’ Airbrake, which is 50 percent larger than the one fitted to the 650S, yet actually lighter. These components, along with the front underbody, side skirts, side intakes, front and rear fenders, rear deck, rear bumper and diffuser, are all crafted from lightweight carbon fibre. Together with the lightened powertrain, and further enhancements including a vented polycarbonate engine cover and titanium exhaust, these features contribute to a dry weight of just 1270kg. At a full 100kg lighter than the already dainty 650S Spider, the 675LT Spider boasts an outstanding power-to-weight ratio of 532PS (525bhp) per tonne.

Beneath the carbon fibre bodywork, the 675LT Spider shares the same uprated suspension as the 675LT Coupé, which incorporates learnings from the McLaren P1™. There is a wider track, and the set-up of the lightweight springs highlights that this is the most track-focused of the Super Series models – stiffness is increased 27 percent at the front and 63 percent at the rear, providing a more rearward balance to work in union with the 40 percent increase in downforce over the 650S Spider.

Lightweight carbon ceramic brakes are, of course, standard, and nestle behind 20-spoke forged alloy wheels – 19-inch at the front, and 20-inch at the rear. The standard 10 spoke wheels together with the bespoke P Zero™ Trofeo R tyres, developed for the 675LT models in collaboration with technical partner Pirelli, make the lightest wheel and tyre set ever offered by McLaren. A further five spoke option is offered, with all wheels available in a choice of finishes. 



The lightweight theme continues throughout the interior of the 675LT Spider, with Alcantara and bare carbon fibre used extensively, and a pair of lightweight carbon fibre-shelled racing seats (modelled on those fitted to the McLaren P1™) saving 15kg. The ‘By McLaren’ interior themes first introduced on the 675LT Coupé are again available for the Spider, but extended with the addition of an exclusive Xenon Yellow leather and matching contrast stitch. Similarly, the exterior paint palette offered on the 675LT Coupé is available, but Solis, a newly developed deep golden colour which derives its name from the Latin for sun, is a bespoke colour only available on the 675LT Spider.

The 675LT Spider is the fifth new model debuted by McLaren in what has become a defining year, and joins the McLaren P1™ GTR, 570S Coupé and 540C Coupé, and the 675LT Coupé as new to the line-up. Further strengthening the Super Series range, first customer deliveries of the new McLaren 675LT Spider will commence in summer 2016.
