The McLaren Super Series 675LT Spider is at the heart of the McLaren range of groundbreaking supercars. Within this family sits the 650S Coupe and Spider, 650S Can-Am and 675LT Coupe. The 675LT Spider is the most focused and engaging McLaren Spider to date. Our lightest supercar. Every gram matters within the powertrain, chassis, body and styling, saving a further 100kg over the 650S Spider. With unique parts reserved for the 675LT 3.8-litre engine, upgraded components provide more power, torque and drivability. Aerodynamics has forged the 675LTs dramatic shape to provide optimum levels of downforce and cooling. The airflow is worked to maximum efficiency across, beneath and through the bodywork.
We have over 50 years of success on the racetrack, and those decades of expertise feed directly into all our road cars. The 675LT is no exception. Inspired by the 1997 McLaren F1 GTR ‘Longtail’, it deploys motorsport-developed technology to create the most extreme driving experience of any McLaren series-production supercar. The 675LT has been extensively optimised within the in-house wind tunnel at the McLaren Technology Centre, an astonishingly potent race-proven engine produces 675PS (666bhp) and 700Nm (516lb ft), and the suspension system has been engineered for even sharper responses. The process might be grounded in hard data, but the result is more engagement, more raw emotion and more mind-blowing performance. The McLaren 675LT propels driving enjoyment to an entirely new dimension.
We raised the bar for driver involvement with the McLaren P1™ chassis setup. The 675LT benefits from many of those learnings, including the adoption of some of its lightweight suspension hardware. The steering rack is 10 percent faster than that found in the rest of the Super Series – faster still than the McLaren P1™ – and spring rates are significantly increased, both measures increasing precision and agility. The result is not only faster lap times but an unrivalled feeling of connection between man and machine. The 675LT has a suspension system that has been radically engineered for extra driver engagement. With significant learnings taken from the McLaren P1™, the 675LT boasts increased agility and a decrease in mass by 13.7kg. The front track is 20 percent wider than that of the other Super Series range, spring rates increase 27 percent at the front, 63 percent at the rear, and an increased rake contributes to 40 percent more downforce. Naturally, the three adjustable suspension settings are uniquely calibrated for the hardcore focus of the 675LT.
Not only does the exterior design of the 675LT create maximum visual impact, but it also helps unleash its staggering performance. The race-inspired front splitter is now 80 percent larger and the distinctive rear ‘Longtail’ Airbrake’s aspect ratio increased by some 50 percent; both additions help increase downforce by an incredible 40 percent compared with the already efficient 650S. The unprecedented use of carbon fibre for a car in this class – including both new bumpers, and the entirely redesigned rear fenders and rear deck – also contributes to a substantial 100kg overall weight saving; a 1230kg dry weight makes the 675LT lighter than all class competitors, and gives an astonishing power-to-weight ratio of 549PS per tonne. Inside, the performance-focused, weight-optimised design continues. Carpet has been removed revealing the carbon fibre MonoCell at the heart of the 675LT. Comfortable yet purposeful racing seats save 15kg, while larger rocker shift gear controls inspired by the McLaren P1™ underline the performance credentials of the 675LT.
