McLaren says "significant customer demand" led it to develop the 675LT Spider, the open-roofed version of the 675LT coupe introduced just this year at the Geneva Motor Show. With coupe production limited to 500 units and wealthy buyers practically buying supercars in bulk, McLaren assured itself of that "significant customer demand." The roadster version is also limited to 500 units worldwide.

Although it is 88 pounds heavier than the hardtop version, the weight is solely due to the mechanism that retracts the three-piece roof. Otherwise, the Spider buyers will get a spec sheet almost identical to the closed-roof model: 666 horsepower and 516 pound-feet from the twin-turbo, 3.8-liter V8, and the 0-to-62-mph sprint completed in just 2.9 seconds. You will only begin to lose time on the run to 124 mph, which takes 0.2 seconds longer in the roadster, and the Spider's top speed of 203 mph is two mph slower than the coupe. Miserly purchasers will be happy to know that fuel economy holds steady at an EPA-certified 18 mpg combined.

The Spider gets a few treats all to itself like the sun-hued Solis paint, optional 20-spoke lightweight wheels, and Xenon Yellow contrast stitching as one of the By McLaren interior options. If you prefer to go inconspicuous, there's a Club Sport Professional Pack that throws a lot of "stealth detailing" at the exterior along with dark wheels. The price comes in at $372,600, if you have to ask. The press release below has more.

- 666 hp and 516 lb-ft provide breathtaking performance, while a retractable roof adds further exhilaration
- 220 lbs weight saving delivers a dry weight of 2,800 lbs, delivering a power-to-weight figure of 4.2 lbs per hp
- Second model to wear the 675LT badge in direct response to significant customer demand
- Exclusive Solis paintwork and 20-spoke Super-Lightweight forged alloy wheels offered for the first time
- Priced at $372,600 USD, the most focused, fastest and exhilarating open top McLaren model ever built will be strictly limited to 500 units globally


NEW YORK, NY (December 3, 2015) – McLaren Automotive has revealed the latest chapter in the history of the iconic 'Longtail' name with confirmation of the 675LT Spider. Strictly limited to only 500 examples worldwide, it is only the second model to wear the LT badge, nearly 20 years McLaren resurrected the name, and is in response to significant customer demand. The 675LT Coupe 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. Sharing these key characteristics, McLaren Automotive now presents the most focused, fastest and exhilarating open top model to ever wear a McLaren badge.

The 675LT Spider, priced at $372,600 USD, is the fifth new model debuted by McLaren Automotive in 2015 in what has become a defining year for the British brand. This latest model joins the McLaren P1™ GTR, 570S Coupe. 540C Coupe and the fixed-head 675LT Coupe as new to the line-up, and further strengthens the Super Series range.

Under the skin of the 675LT Spider sits the heavily revised 3.8-liter twin turbo V8 powertrain from the Coupe sibling, ensuring performance figures are worthy of the LT – or 'Longtail' – badge. The power output and torque figures remain unchanged, with 666 hp (675PS) delivered at 7,100 rpm and 516 lb-ft (700Nm) available between 5,000-6,500 rpm. The changes to the powertrain saw more than 50 percent of the components replaced to ensure optimized 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 0-62 mph (0-100km/h) takes just 2.9 seconds, and 124 mph (200km/h) is achieved in 8.1 seconds – giving away only 0.2 seconds to the more aerodynamically optimized and lighter Coupe. Controlled torque delivery in first gear manages torque to 443 lb-ft (600Nm) to ensure maximum acceleration, and minimizing wheel slip. Top speed is 203 mph (326km/h). Despite these blistering performance figures, the 675LT Spider returns an EPA-rated 18 mpg in combined city/highway driving, while CO2 emissions remain at 275g/km – the same as the Coupe. A three-piece retractable folding hardtop can be opened at speeds up to 19 mph (30km/h) 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 675LT Spider has been developed with a focus on light weight and optimized aerodynamic performance. The special nature of the model is supported by the extensive use of carbon fiber for the bodywork. As with the 675LT Coupe, 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 fiber. Lightweight components are also found throughout the powertrain and chassis, all contributing to a dry weight of just 2,800 lbs (1,270kg). This weight is a full 220 lbs (100kg) lighter than the already lightweight 650S Spider, and gives a power-to-weight figure of 4.2 lbs per hp. Due to the inherent strength of the carbon fiber MonoCell chassis, no further strengthening – and associated weight increase – has been added through the removal of the roof, and the 675LT Spider is only 88 lbs (40kg) heavier than the Coupe, all due to the retractable roof system.

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 models. This is integrated into 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 louvers in the flared rear bumper optimize pressure levels.

The 675LT Spider shares the suspension set up and geometry of the Coupe, 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 models, 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.

As standard, the 675LT Spider is fitted with 10-spoke Ultra-Lightweight forged alloy wheels – 19-inch at the front, 20-inch at the rear – and P Zero™ Trofeo R tires, developed for the 675LT models in collaboration with technical partner Pirelli. These are the lightest wheel and tire set ever offered by McLaren. Two Super-Lightweight wheel options are optionally available; a new 20-spoke design, offered in liquid metal or diamond cut finishes, and the five-spoke Super-Lightweight design which debuted on the Coupe.

The lightweight theme continues throughout the interior with Alcantara® and bare carbon fiber used extensively. A pair of lightweight carbon fiber-shelled racing seats, modelled on those fitted to the McLaren P1™, save a combined 33 lbs (15kg), and feature '675LT' embossed leather to provide enhanced levels of support and grip. As seen in the McLaren P1™ and 675LT, heating and ventilation controls are located within the portrait-orientated, centrally-mounted touchscreen, which also operates the four-speaker Meridian audio system, while air conditioning has been removed. The 35 lb (16kg) system can be specified as a no-cost-option.

The 'By McLaren' interior themes were first introduced on the 675LT Coupe, and are again available for the Spider model. The range is extended for the 675LT Spider, with the addition of exclusive Xenon Yellow contrast stitch. Simialrly, the full exterior paint palette offered on the 675LT Coupe is available for the Spider model, which includes the new Silica White, Delta Red, Napier Green and Chicane Grey paint finishes. In addition, the newly developed deep golden color, Solis – which derives its name from the Latin for sun – is a bespoke color only available on the open-top 675LT Spider.

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. McLaren Orange detailing is then applied both externally and internally, with brake callipers, embossed leather and stitching all in the heritage color made famous by the Formula 1™ and Can-Am racers of Bruce McLaren.

Another key characteristic of any Longtail is exclusivity, and the 675LT Spider is no exception. As with the Coupe, production of the 675LT Spider will be strictly limited to only 500 examples, with first deliveries in summer 2016.

THE STORY OF LT
The story of the McLaren F1 is one of the most famous in automotive history, with the all conquering GTR moving the game on further, worthy of a place in the motorsport hall of fame. After a successful season in 1995 and 1996, McLaren set about raising the bar once more in order to stay ahead of the competition. 

While the name and basic architecture remained the same, the 1997 McLaren F1 GTR 'Longtail' – or LT – was completely re-engineered from the ground up, and was the ultimate version of the iconic McLaren F1. With enhanced levels of downforce through extended bodywork, and dramatic weight savings, the end result was the most track-focused derivative of all 106 models to wear the McLaren F1 badge. 

The McLaren F1 GTR 'Longtail' raced successfully during the 1997 sports car racing season, including most prominently in the FIA GT championship against specially developed racing 'prototypes', and went within a whisker of winning the world title. Notable achievements included victory in the Silverstone 4 hours, the Hockenheim 4 hours, the Spa 4 hours and a 1-2 class finish – 2-3 overall – at the 1997 24 Hours of Le Mans. Despite racing against the much quicker LMP cars, only one lap separated the #41 McLaren F1 GTR 'Longtail' from outright victory. The nearest opposition in the GT1 class finished nearly 30 laps behind.

And so, McLaren has done it again. 'LT' is now the ultra high-performance brand, re-establishing the McLaren 'Longtail' heritage. With two models now wearing the iconic badge, the 675LT Coupe and 675LT Spider embody the 'Longtail' ethos, with a focus on light weight, enhanced aerodynamics, increased power, track-focused dynamics and driver engagement.
