McLaren 675LT Spider
McLaren 675LT Spider was revealed at the end of 2015 as the latest chapter in the history of the iconic ‘Longtail’ name, and was the fifth new model debuted during a truly defining year for McLaren Automotive. Strictly limited to only 500 examples worldwide which sold out in just two weeks, it is only the second model to wear the LT badge. This latest model arrived less than a year since the first model in nearly 20 years resurrected the name, and was in response to significant customer demand. The 675LT Coupé focused on light weight, enhanced aerodynamics, increased power and track-focused dynamics, and this limited-run model quickly sold out before the first deliveries commenced.
The McLaren 675LT Spider, only the second McLaren in nearly two decades to wear the LT – or ‘Longtail’ – name, stays true to the spirit of its iconic predecessor with aerodynamically optimised, dramatically enhanced styling that results in 40 percent more downforce than the 650S Spider which it sits alongside in the McLaren Super Series.
‘The Longtail is a famous name in the history of McLaren, first used on the fastest version of the iconic McLaren F1,’ explains Mike Flewitt, McLaren Automotive Chief Executive Officer. ‘The McLaren F1 GTR ‘Longtail’ was the final highly successful iteration of the F1, and it is an appropriate name for the most exhilarating and driver-focused version of the Super Series. The 675LT is the purest distillation of what McLaren stands for – pure driving pleasure.’
The main focus for the McLaren 675LT Spider is clear: to deliver maximum performance, engagement and excitement. To achieve this, weight has been reduced by 100kg through the increased usage of carbon fibre – the signature material of McLaren – and by lighter components throughout, including newly developed suspension geometry derived from the McLaren P1™, resulting in an increased track of 20mm. Under the skin sits the heavily-revised 3.8-litre twin turbo V8 powertrain from the Coupé sibling, ensuring performance figures are worthy of the LT badge.
The power output and torque figures remain unchanged, with 675PS (666bhp) delivered at 7,100rpm and 700Nm (516lb ft) available between 5,000-6,500rpm. The changes to the powertrain saw more than 50 percent of the components replaced to ensure optimised levels of power, torque and drivability. These include new, more efficient turbos, detail design changes to the cylinder heads and exhaust manifolds, new camshaft and lightweight connecting rods, and a faster-flowing fuel pump and delivery system.
Acceleration from 0-100 km/h (0-62 mph) takes just 2.9 seconds, and 200 km/h (124 mph) is achieved in 8.1 seconds – giving away only 0.2 seconds to the more aerodynamically optimised and lighter Coupé. Controlled torque delivery in first gear manages torque to 600Nm (443lb ft) to ensure maximum acceleration, and minimising wheel slip. Top speed is 326 km/h (203 mph).
Despite these blistering performance figures, the 675LT Spider returns 24.2mpg on the EU combined cycle, while CO2 emissions remain at 275g/km – the same as the Coupé. A three-piece retractable folding hardtop can be opened at speeds up to 40 km/h (25 mph) to allow for a new level of open-air exhilaration.
Staying true to the ‘Longtail’ ethos, established by the McLaren F1 in the late 1990s, the McLaren 675LT Spider has been developed with a focus on light weight and optimised aerodynamic performance. The special nature of the model is supported by the extensive use of carbon fibre for the bodywork. As with the 675LT Coupé, the front bumper with larger splitter and end plates, front under body, side skirts, side intakes, lower side intakes, rear bodyside lower, rear fenders, rear deck, rear bumper, diffuser and ‘Longtail’ Airbrake are all carbon fibre.
Lightweight components are also found throughout the powertrain and chassis, all contributing to a dry weight of just 1,270kg. This weight is a full 100kg lighter than the already lightweight 650S Spider, and gives a power-to-weight figure of 532PS per tonne. Due to the inherent strength of the carbon fibre MonoCell chassis, no further strengthening – and associated weight increase – has been added through the removal of the roof, and the McLaren 675LT Spider is only 40kg heavier than the Coupé, all due to the retractable roof system.
