Mazda MX-5 1989-2014 in pictures: 25 years of everyone's favourite roadster

It's hard to believe but the Mazda MX-5 celebrates its 25th birthday this year, writes Adam Binnie. The occasion will be marked with a special edition model, before the launch of the fourth-iteration MX-5 in September 2014. The MX-5 earned the title of 'bestselling two-seater sports car of all time' from Guinness World Records in May 2000, after global production reached 531,890 units.

BMW i3 Coupe concept

It may be dubbed a concept but this BMW i3 Coupe is ostensibly the debut of the production version of the innovative new B-segement EV at the LA auto show. The Coupe is a new variation on the now-familiar i3 although in reality it's more three-door than true coupé. At 3,964mm, 1,768mm wide and 1,555mm high, the Coupe is lower than the five-door i3, while its front and rear screens have faster rakes.
