Inspired by the carbon-bodied McLaren P1 MSO

The McLaren 675LT was launched in 2015 as a higher performance version of the 650S. Named the LT as a tribute to the McLaren F1 GTR "Long Tail," the 675LT is the quickest and most powerful member of the Super Series family. It is also the most exclusive, being built in a limited edition of only 500 units. A targa-top, Spider version was also launched, also limited to 500 examples, and both versions sold like hot cakes.

With the car still in production as of June 2016, but with no way to buy it, McLaren is rubbing more salt into the wound by launching an even more exclusive version of the 675LT. Dubbed Carbon Series LT, this new sports car is based on the 675LT Spider and was inspired by the carbon-bodied P1 the British firm unveiled at the 2016 Geneva Motor Show. The special-edition model is limited to only 25 units and, as it usually goes with such vehicles, all have been purchased by loyal customers already.

Production of the Carbon Series LT will begin this autumn at the McLaren Special Operations shop. First deliveries are expected before the end of 2016. McLaren didn’t say whether the Carbon Series LT will also get a coupe version, but until that happens, let’s have a closer look at this all-carbon Spider model.

What makes the McLaren MSO Carbon Series LT special

Produced in response to requests from McLaren customers captivated by the visual carbon-fiber-bodied P1, the Carbon Series LT is pretty much a standard 675LT with extra carbon-fiber. That’s quite the big deal given that the regular Spider model already has the front bumper, front under body, side skirts, side intakes, lower side intakes, rear bodyside, rear fenders, rear deck, rear bumper, diffuser and "Longtail" Airbrake crafted from carbon-fiber in a gloss finish. MSO increased the 675LT’s carbon components by around 40 percent, building the retractable roof and tonneau, A-pillars, engine hood and rear deck, side blades, front and rear wings, and even the fuel filler flap from the lightweight material. These elements also received high-gloss treatment, which reveals the inherent weave of the carbon-fiber. For added exclusivity, the Carbon Series LT also received the functional louvers of the 650S GT3 race car. Pretty cool huh?

The interior of the limited-edition sports car was carried over from the standard vehicle, but this shouldn’t be an issue with the car’s exclusive buyers, which will probably opt for special finishes and features. The only thing that sets the Carbon Series LT apart is the Track Telemetry pack — usually an option — which adds three track cameras.

Motivation comes from the same twin-turbo, 3.8-liter V-8 found in the 675LT Spider. The unit is rated at 666 horsepower and 516 pound-feet of torque, a 25-horsepower and 16-pound-foot increase over the 650S. Although the Carbon Series LT is slightly lighter thanks to the added carbon-fiber parts, performance remained unchanged according to McLaren. The sprint from 0 to 62 mph takes 2.9 seconds, while the 124-mph mark is reached in 8.1 ticks. Top speed is a mind-boggling 203 mph.

No word on pricing as of this writing, but given that the 675LT Spider retails from around $385,000, it’s safe to assume that the Carbon Series LT fetches in excess of $450,000 before options.

The 675LT Spider was launched in December 2015 as the seventh member of the Super Series family, which already includes the 650S, 625C, 650S Le Mans, and the track-only 650S GT3. Essentially identical to the coupe version minus the removable top and revised C-pillars, it gets its juice from the same 666-horsepower, 516-pound-foot, 3.8-liter V-8. It needs only 2.9 seconds to hit 62 mph, identical to the coupe, and 8.1 ticks to reach 124 mph, two tenths slower than the fixed-roof variant.

Press Release

McLaren Special Operations, the bespoke division of McLaren Automotive, has announced the creation of the MSO Carbon Series LT. Strictly limited to 25 units globally – all already sold – and based on the 675LT Spider, the Carbon Series LT has been produced in response to requests from McLaren customers captivated by the visual carbon fibre bodied McLaren P1™displayed recently at the International Geneva Motor Show.

Staying true to the ‘Longtail’ ethos, established by the McLaren F1 in the late 1990s, the MSO Carbon Series LT has been developed with a focus on light weight and optimised aerodynamic performance. Applying gloss carbon fibre to the entire body of the car further extends its appeal to bring a brutal beauty to the existing 675LT Spider body, showcasing the skills of the McLaren bespoke division.

As with the 675LT Spider, 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 but with a gloss finish revealing the inherent weave of the material. In addition, the MSO Carbon Series LT is fitted with a gloss finished carbon fibre electrically retractable roof and tonneau, A-pillars, bonnet and rear deck, side blades, complete front and rear wings, and even fuel filler flap. The McLaren Track Telemetry pack, which includes three track cameras, is fitted as standard equipment. The front wings also feature GT3-inspired functional louvres.

In total, the MSO Carbon Series LT features around 40 percent additional carbon fibre parts over the standard car, requiring significant additional development work by the team of MSO craftsmen. It is therefore not possible to retro-fit the gloss carbon fibre body to an already ordered 675LT Spider and the 25 units supplement the previously announced 500 editions of the standard car that sold out in weeks after the car’s debut on December 4, 2015.

The MSO Carbon Series LT is only the third model to wear the LT badge. The first, the 675LT Coupé, arrived last year resurrecting the ‘Longtail’ name after nearly 20 years. 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. Sharing these key characteristics, McLaren Automotive added the most focused, fastest and exhilarating open top model to ever wear a McLaren badge with the 675LT Spider, further strengthening the ‘LT’ brand.

Under the gloss carbon fibre skin of the MSO Carbon Series LT sits the heavily-revised 3.8-litre twin turbo V8 powertrain from its 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).
