McLaren Special Operations (MSO), the division of McLaren Automotive responsible for the delivery of bespoke projects, will present a breathtaking one-off supercar at The Quail, an exclusive event on August 17, 2012 that is a highlight of the Pebble Beach weekend in Monterey, USA.
Called the McLaren X-1 and based structurally on the company’s groundbreaking carbon MonoCell but with a totally unique body, it has been created for an anonymous car enthusiast.
he X-1 is the most ambitious example yet of MSO’s expertise. It has a whole new body made of advanced materials. Everything is bespoke, even down to the lights and wheels, necessitating new testing and homologation meaning the car took two and a half years to build, a process that began before the styling was signed off.
The X-1 had its own development programme because crucially, this wasn’t to be a fragile concept car that would never see tarmac. It was to be a usable car, road legal and capable of travelling at supercar speeds. It also had to comfortably seat two adults so although the 12C was already as shrink-wrapped as it could be from a packaging perspective, the ingenious flexibility of the MonoCell allowed the creation of a completely different form while maintaining the engineering purity of a McLaren.
A full CFD (Computational Fluid Dynamics) aerodynamic testing schedule ensured high-speed stability, and the car also completed approximately 625 miles of testing including two intensive testing stints at the Idiada circuit in Spain with chief McLaren test driver, Chris Goodwin. After testing, the whole car was meticulously rebuilt, by hand to concours standard.
The doors have also been developed specifically for the X-1, although they retain the dihedral action and twin hinges, and the roof is also new. Externally, only the glasshouse is carried over from the 12C.
The unique body of the X-1 means most dimensions have changed. The X-1 is 4658mm long – 109mm longer than a 12C. Width is 2097mm (with mirrors) – an increase of 188 mm. Despite the revised roofline, the height remains the same, at 1199mm. Kerb weight is almost identical (about 1400kg), as the lighter carbon body panels compensate for the greater length and width. Light weight, as with all McLaren projects, was a priority.
While the basic architecture of the interior did not change, personalisation includes bespoke Harissa Red McLaren Nappa leather used for the seats, door and roof trim, and switchgear with machined nickel-coated, aluminium bezels. The carbon interior trim has a titanium weave, to give a magical 3D-like effect. Special Andesite tufted carpet covers the floor.
All these changes ensured the X-1 needed special homologation for road use. The car has been thoroughly engineered to be usable and road legal. The X-1 shares the same the major mechanical components as the 12C, including the twin-turbo 625PS engine, giving astonishing acceleration and top speed.
