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.

Detroit Auto Show: Bentley Continental GTC Speed debuts

Bentley will complete its Speed portfolio when it introduces a freshened Continental GTC range at the Detroit auto show. Along with exterior and equipment changes, a new GTC Speed model is added with a more powerful version of the 6.0-liter twin-turbocharged W12 that churns out 600 hp and 553 lb-ft of torque for an improvement of 48 hp and 74 lb-ft over the regular GTC. The result is Bentley's most powerful convertible to date.

Driven: BMW 335i Cabriolet

The 3 series has come a long way. While the original 1975 E21 was initially only available as a two-door sedan, it was soon transformed into a cabriolet thanks to an aftermarket conversion kit by Baur. In 1982, the E30 was a two or four-door sedan until several years later, when BMW offered the "Touring" wagon and the full factory-produced cabriolet.
