McLaren P1 - How much of it is actually British?

[GeorgeV12]

I was wondering exactly how much of the P1 is actually made by McLaren themselves and how much is outsourced overseas. I mean I am sure if you took any supercar and brought it down to its component parts I am sure there would be a number of components manufactured by other companies such as brakes by Brembo etc.

Please do correct me if I am wrong but the following I know so far...

I know the engine is made by Ricardo PLC in Sussex but under licence from Nissan who originally designed the motor. Same unit is used in the 12C as I know but revised to accomodate the bolt-on electric motor and has new heads.

The tubochargers are made by MHI Inc (Mitsubishi Hardware Incorporated) in either China or Japan, not sure where.

The brakes are made by Japanese firm Akebono, where they are made I do not know but their website claims the majority of production is in China. However, they also have production sites in Japan and the US.

The chassis or rather the carbon 'Monocell' tub is made by a company over in Salzburg, Austria called Carbo-Tech which was carried over unchanged from the 12C.

The gearbox was made in Turin, Italy by Graziano Trasmissioni but I am not sure if it is the same unit but altered from the 12C or an all-new gearbox.

Tyres obviously outsourced by Pirelli.

I know it may sound like I am trying to pick holes in the P1 and run it down but I am not, I am just interested in how much of a global effort goes into the production of this car seeing as some people keep claiming it as the "all British supercar". I am a fan of the P1 myself and wish to gain more knowledge on it. Also please correct me if I am wrong on any of the details above.

Thanks for the information guys, I didn't know about the monocage! I am yet to see one in the flesh, I like the way it has the almost clear rear grille around the exhaust outlet, reminds of the F50 and how you could see its internals through the back.
