Powered by McLaren’s 3.8l turbocharged V8 offering 650 HP, the 650S will slot between the two existing supercars from McLaren, 12C and P1. As pre information leaked, it is revealed that the 650S is an improvised version of 12C and has been developed with help form Formula 1 driver Jenson Button. McLaren 650S has better tyres, better aerodynamics, better suspensions and brakes.
Apart from this, there is also not much of a difference in power output of the two (12C generates 625 HP). This could be damaging for the 12C as it might get replaced by the 650S in countries or markets where buyers only want the top-notch stuff. Whatever is the case, official details will be out very soon.
