McLaren has officially unveiled the X-1 concept at the Pebble Beach Concours d'Elegance.

Created for an "anonymous car enthusiast," the one-off model was built by McLaren Special Operations (MSO) and is based on the MP4-12C.

According to MSO Program Director Paul MacKenzie, "One of our clients who already owned a McLaren F1, a Mercedes-Benz SLR McLaren and now a 12C, wanted a unique car. The conversation began with our Executive Chairman Ron Dennis almost three years ago - before the 12C was even launched. The client wanted a machine that had all the capability of the 12C but wrapped in a unique body that reflected his needs and personality."

Mackenzie and Design Director Frank Stephenson meet with the client for three hours to discuss his ideas for the model. He said it should borrow cues from classic cars (a 1961 Facel Vega, a 1953 Chrysler D'Elegance Ghia, a 1959 Buick Electra, a 1939 Mercedes-Benz 540K and a 1971 Citroën SM), a Jaeger LeCoultre clock, an Airstream trailer, a Thomas Mann Montblanc pen, a grand piano and an eggplant.

The client then hosted a competition which pitted McLaren's designers against others outside the company. In the end, a design by McLaren's Hong Yeo was chosen and the client signed off on production.

The resulting model features futuristic styling with a number of retro-inspired touches. Highlights include carbon fiber body panels, unique head- and taillights, custom wheels, solid aluminum trim and covered rear wheels.

The interior carries over from the MP4-12C, but has been equipped with Harissa Red Nappa leather upholstery, nickel-coated aluminum switchgear and titanium-weave carbon fiber trim.

Detailed performance specifications were not released, but McLaren said the car weighs approximately 1400 kg (3086 lbs) and "shares the same the major mechanical components as the 12C, including the twin-turbo 625 PS (460 KW / 616 hp) engine."
