Alpha Romeo will debut the convertible version of its mid-engined sports car, the 4C at the Geneva Motor Show. From the front, the 4C Spider and the 4C Coupe are identical. The Spider sports a more pronounced rear, three heat extractors and a subtle spoiler. It also gets a body coloured engine cover. The coupe will also get all-new wheel designs.

To turn the coupe into a Spider, the company has built an all-new aluminium rollover structure, custom carbonfibre windscreen frame and high-strength steel engine cross bars. The Spider will also come with an all-new carbonfibre air intake system. It will also get an optical carbonfibre hardtop.

The 4C Spider will be powered by the same engine as the coupe, a 240bhp TBi. Alpha has claimed a 0-100kph time of 4.5 seconds for the Spider.

The Spider will offer a premium leather interior with accent stitching. The cabin will also get carbonfibre vent surrounds, along with an all-new audio system.

The car will be revealed alongside the updated 4C Coupe.
