MSO Carbon Series LT

Following the customer reaction of the carbon fibre bodied P1, McLaren applies the same body treatment to its 675 LT Spider.

McLaren Special Operations (MSO), the bespoke arm of McLaren, has announced the creation of the MSO Carbon Series LT, all 25 of which are already accounted for.

As with all models in McLaren’s 25-plus year history, the Carbon Series LT focuses on light weight and aerodynamics in the classic Longtail design. Now the car was already carbon fibre intensive in its body panel manufacture, but adds another 40% of high-gloss-finished carbon-weave application for the electrically retractable roof and its tonneau, A-pillars, hood, rear deck, side blades, front and rear fenders, and the fuel filler flap.

It seems like basic addition, but the company points out that the additional carbon fibre work required extensive adaptation of the panels, meaning that owners of the 675LT Spider cannot retrofit their cars with the new panels. Five hundred 675LTs have been sold since the car was introduced in December 2015, though not all have been delivered.

The front fenders feature GT3-inspired functional louvres, and the car also features three track cameras as part of McLaren’s Track Telemetry pack (which is standard fitment on the roadster.

The MSO Carbon Series LT is the third car in McLaren’s stable to wear the LT (for Longtail) moniker, which in the McLaren house also means light weight, enhanced aerodynamics, increased power and track-focused dynamics.

Under the skin, things have also been extensively changed. The car is powered by the same 3.8-litre twin turbo V-8, putting out an identical 666 hp and 516 lb-ft of torque despite changing more than 50% of its components (including more efficient turbochargers, new camshafts, and connecting rods, cylinder head design, exhaust manifold, and a faster fuel pump and delivery system.

Acceleration from zero to 100 km/h takes just 2.9 seconds, while another 5.2 seconds is required to get it up to 200 km/h. That’s just 0.2 seconds off the time from the aero-optimized 875LT coupe. Top speed is 326 km/h.

The car goes into production in fall 2016 with the first cars in customers’ hands by the end of the year.
