From a standing start less than a decade ago, McLaren has ridden out some early speed bumps and gone on to blow our collective minds with the likes of the 570S, 675LT, and P1. The 720S signals another major milestone: this is the first time McLaren has completely replaced one of its core cars.
Development work started back in 2013, before the 650S had even been announced, and a big chunk of it was done virtually. The first full validation car was only built and driven 11 months ago, so its path to market has been extremely rapid.
McLaren says 91% of the 720S is new, and the enlarged 4.0-litre engine features 41 per cent new content: turbos, intercoolers, cast-aluminium plenum, cylinder heads, crankshaft, pistons, and exhaust. Topline numbers include 710bhp, 568 torques, 249 CO2s, 0-62mph in 2.9 seconds, 0-124mph in 7.8, and 0-186mph (300km/h, if you prefer) in 21.8.
