McLaren 650S priced from £195,250 and does 0-62mph in 3.0 seconds

The new McLaren 650S (pictured) costs from £195,250 It’s only ten days since the McLaren 650S was revealed as a more hardcore version of McLaren 12C supercar – and with more than a hint of P1 styling – but McLaren are already building it and have revealed performance and price details. Available as either a 650S Coupe or 650S Spider, the starting point is £195,250 for the Coupe and £212,250 for the Spider, that’s almost £20k more for the 650S Coupe than the 12C Coupe and £17k more for the Spider. But apart from the more dramatic styling, increased downforce and tweaks from the extra power – the 650S gets 641bhp – to the improved handling and dynamics, you also get increased levels of optional equipment including carbon racing seats from the P1, rear parking camera and full carbon fibre interior.
