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.

BMW i3 Range Extender engine adds 10% to the price

BMW i3 Range Extender engine adds 10% to the price The BMW i3 – BMW’s first foray in to a world of electric cars – was officially revealed in July – and due on sale in 2014 – and seems, by electric car standards, to be almost affordable. At a starting price of £30,680 – £25,680 after the taxpayer bribe for EV buyers – it’s no more expensive than other electric cars and does come with some clever technology – and the BMW badge – that will help it move out of showrooms. But as we reported as far back as 2011, the BMW i3 is to get a range-extender option – a small petrol engine that kicks in to recharge the batteries when they get low – which will make the i3 a much more practical proposition.

Kimi may quit again

KIMI RAIKKONEN has revealed he will likely quit Formula One again once his current deal with Ferrari expires at the end of 2015. Raikkonen dropped the bombshell at Silverstone ahead of the British Grand Prix this weekend, and just eight races into his second coming at Ferrari which has so far been a bitter disappointment. Struggling with a car not to his liking, the hotly-anticipated scrap with team-mate Fernando Alonso has failed to materialise as the Spaniard has comfortably out-qualified and out-raced the Finn.
