McLaren is ending the era of the P1 in a big, big way next month at Geneva. Presenting the one-off, McLaren Special Operations (MSO), P1. Why is this one particularly special? Because it has a full visual carbon fiber body which has been hand-laid with a bespoke "Lio Blue" tinted lacquer. This is the first time the full visual carbon fiber body conversion has ever been displayed in public, though it was made available to P1 buyers earlier in the year.

Other visual upgrades to the MSO P1 include a gloss black finish to the wheels, and an extensive retrim of the interior with carbon black Alcantara and contrasting blue stitching. Oh, and there's the 24-carat gold exhaust heat shield that pays homage to the McLaren F1. We're totally smitten. Our weak knees then gave out completely when we laid on this: MSO's one-off, carbon fiber-themed 675LT Spider. Finished in Ceramic Grey, it features a satin carbon-fiber retractable hardtop and tonneau that not only cuts weight by 1 kg (just over 2 lbs.), but can be operated at speeds of up to 25 mph.

The front wings include carbon fiber louvres and the "Longtail" Airbrake is finished in the same body color on top, while the lower plane shows the natural carbon fiber weave. The front bumper end plates, side skirts, side intakes and rear bumper are also finished in visual carbon. Inside, there are Alcantara trimmed racing seats with Xenon Yellow contrast stitching. Like the MSO P1, there's a 24-carat gold heat shield, only this time it's visible through the exposed engine bay around the titanium exhaust system. Performance remains unchanged. We'll bring you full coverage from Geneva in just a few weeks where McLaren will also reveal a new addition to the Sports Series.
