As the newly-launched McLaren 600LT Spider enters production, McLaren Special Operations (MSO) is aiming to give customers a taste of its customisation programme at the upcoming Geneva International Motor Show with a specially curated design. Enter the 600LT Spider by MSO, a tailor-made model that’s commissioned as a tribute to its predecessor, the 675LT.

To start, the hand-built Geneva show car is finished in solid Dove Grey paint, contrasted with Napier Green highlights that help accentuate the Longtail’s key design elements, such as the front splitter, sills, rear diffuser and door inserts. The bright green shade harks back to the 675LT, for which Napier Green was one of the original hues. Since then, the colour is only available as an MSO Bespoke colour.

The application process of the Napier Green accents is a first for McLaren road cars – the colour is applied using a new technique that sees the paint applied onto a light and flexible film, which ensures a premium quality bespoke colour match. This process has previously been used on the 720S GT3 and 570S GT4 race cars, and the contrast-colour film will be available as a bespoke option in the future.

Being a Longtail, the 600LT Spider by MSO’s front fender louvres are made from carbon-fibre, and the retractable hard-top is finished in MSO Bespoke Carbon Black. To complete the stealthy look, the 10-spoke ultra lightweight forged alloy wheels are finished in gloss black, and the brake calipers get the Napier Green colourway as well.

The exterior theme continues into the cabin – the green contrast stitching are used throughout the seats and door inserts, as well as the 12 o’clock marker on the steering wheel. The 600LT is also optionally equipped with super-lightweight carbon-fibre racing seats, which was originally developed for the Senna.

MSO Bespoke additions on show include 600LT headrest embroidery, Alcantara headlining and steering wheel and a range of MSO ‘surprise and delight’ features for owners to find. These include an accelerator pedal etched with 600LT branding and an MSO dedication plaque. Items like the door inserts and tunnel sides are made from unpainted carbon-fibre.

Like all Longtail models, the 600LT Spider by MSO is a track-focused machine that’s fitted with a mid-mounted M838T 3.8 litre twin-turbo V8 with 600 PS and 620 Nm of torque. The engine is paired with a seven-speed dual-clutch Seamless Shift Gearbox (SSG), with drive sent to the rear wheels. The century sprint is done in 2.9 seconds, and onwards to a top speed of 324 km/h. Also fitted is the McLaren Track Telemetry (MTT) with lap time function and three cameras.

MSO managing director, Ansar Ali said: “Almost half of 600LT Coupé buyers have benefitted from MSO’s services, so it makes perfect sense to curate our own 600LT Spider to mark its debut at the Geneva Motor Show.”

“Our design team relished the opportunity to accentuate the 600LT’s cutting-edge looks and with painstaking attention to detail, including the use of innovative materials, we’ve showcased our craftsmanship too. Few cars deserve MSO’s personalisation more than a McLaren Longtail and we can help our clients realise their visions with a car of their own making,” he added. Production of the 600LT will be limited, with build slots scheduled around other Sports and Super Series models.
