Recently spotted on the streets of London were two very rare McLaren MSO HS models. I say they're rare because McLaren is only introducing 25 of them into the world and this is one of the first sightings of the model.
(Related - 2016 McLaren P1 GTR In-Depth Review and Start Up)This model is based on the Super Series Coupe body, but has many modifications that set it apart from the rest. Right off of the bat, you'll notice the new carbon fiber front bumper, splitter, bonnet, roof, side skirts, side intake and the rased rear wing. The massive wing was developed with information and experience gained from the McLaren P1 GTR program, retaining the airbrake but it can be electronically altered for track use. As for its power, it uses the M838TL twin-turbo V8 engine, but is capable of 678 hp and 516 lb-ft of torque. As stated previously, only 25 examples of this car will be produced and they are already ordered by request/ are sold out.
