McLaren MSO HS


The brand-new MSO HS will be officially unveiled to the public. This striking-looking 650S-based Macca, leaked on the internet by our friends at Jalopnik with the help from an unnamed source, will be close to the top of McLaren's food chain, surpassed only by the almighty P1.

Like the 675LT, it builds upon the 650S and it features carbon-fiber bodywork that increases downforce even more (the 675LT was aerodynamically chiseled to increase downforce by 40 percent over any other model in the Super Series).


The enormous rear wing, for example, is said to be derived from the P1 GTR’s program and uses throttle mapping to adjust itself electronically for street or track use. It even acts as an air brake and generates 220 kg of downforce at 241 km/h.

Other notable body panels finished in exposed carbon-fiber are the front bumper splitter and dive planes, the sides skirts with the side intake, and the hood and the roof – which comes with an air-feeding scoop.


These add-ons are all part of McLaren’s weight-saving obsession, bringing the total weight of the car down by around 40 kg; even the windscreen and the side windows went through a weight-shedding process, while the engine cover was made out of polycarbonate.

Compared to the 675LT, the M838T 3,799 cc twin-turbo V8 petrol engine under the MSO HS’ hood produces 13 PS  more, bringing the total up to 688 PS. The 700 nm torque figure remains the same, but Jalopnik says it’s available from 3000 Rpm all the way up to 7000 Rpm.


It will feature all the track goodies found on the 675LT, including the McLaren Track Telemetry – a system which analyses your lap times and details with the help of three cameras, GPS mapping, and graphical plots, in order to improve your circuit performance.

Only 25 examples are reportedly going to be built, so getting your hands on one is not going to be easy.
