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. Staying true to the LT (Longtail) ethos, established by the McLaren F1 in the late 1990s, the 675LT Spider has been developed with a focus on light weight and optimized aerodynamic performance. The special nature of the variant is supported by the extensive use of carbon fiber 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 LT Airbrake are all carbon fiber.
The dramatic styling and purposeful stance of the 675LT is retained with the Spider variant, with the extended front splitter flanked by front wing end plates, each working the airflow harder and increasing downforce. Sculpted carbon fiber door sills run along the lower edge of the bodywork, flowing in to a smaller air intake ahead of the rear wheels. This sits below the more pronounced side intake, with both feeding clean, cool air into the side radiators which are more prominent to offer increased cooling. The retractable hard top stows below a color-coded tonneau cover, and the engine remains visible through a lightweight vented polycarbonate engine cover. At the rear, the lightweight titanium crossover twin exhausts exit below the active ‘Longtail’ Airbrake which is 50 percent larger than other Super Series versions. This is integrated in to the design of the flowing rear wings and despite the larger size, carbon fiber construction ensures weight is actually reduced. Exposed bodywork across the rear deck and below the rear wing aids engine cooling, while louvres in the flared rear bumper optimize pressure levels.
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 fiber MonoCell chassis, the 675LT Spider is only 40kg heavier than the Coupé, all due to the retractable roof system.
In addition, further enhancements can be made through the Club Sport Professional Pack, which adds further visual carbon fiber and stealth detailing. Available in Titanium Silver, Storm Grey, Onyx Black and Chicane Grey, the Ultra-Lightweight wheels are stealth finished, while a satin carbon fiber finish is applied to the front wing end plates, lower side air intake and the center of the rear bumper, along with the side intakes, wheelarches, wing mirrors and ‘Longtail’ Airbrake. Completing the aggressive look of the 675LT Spider are the 10-spoke Ultra-Lightweight forged alloy wheels, shod with 19-inch P-Zeros at the front and 20-inch at the rear.
Inside, the McLaren 675LT Spider takes up the Coupe version’s ‘By McLaren’ interior themes. The range is extended for the 675LT Spider, with the addition of exclusive Xenon Yellow contrast stitch. With McLaren Orange detailing applied, brake callipers, embossed leather and stitching all adorn the famous hue of Bruce McLaren. While retaining much of the track-focus and capability of the Coupé, the Club Sport Pack, comprising titanium rollhoop, four point harnesses and fire extinguisher. is not available as an option for the 675LT Spider.
Under the skin of the 675LT Spider sits the heavily revised 3.8-liter twin turbo V8 powertrain from the coupé sibling, ensuring performance figures are worthy of the LT (Longtail) 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 optimized levels of power, torque and drivability. Acceleration from 0-100kmh takes just 2.9 seconds, and 200kmh is achieved in 8.1 seconds, giving away only 0.2 seconds to the more aerodynamically optimized and lighter coupé. Controlled torque delivery in first gear manages torque to 600Nm to ensure maximum acceleration, and reducing ing wheel slip. Top speed is 326km/h (203mph).
The 675LT Spider shares the suspension set up and geometry of the Coupé, with the front end sitting on new lightweight springs and a wider track, increased by 20mm. Spring rates are the most track-focused of the Super Series, with stiffness increased 27 percent at the front and 63 percent at the rear, providing a more rearward balance and allowing for a 40 percent increase in downforce over the 650S Spider.
With deliveries starting 2nd quarter of 2016, the McLaren 675LT Spider is priced from 285,450 pounds. The 675LT Spider Super Sports is offered with the full exterior paint palette of the 675LT Coupé, including the new Silica White, Delta Red, Napier Green and Chicane Grey. In addition, the newly developed deep golden color, Solis, is a bespoke color only available on the open-top 675LT Spider.
