BMW has confirmed that its i8 Concept Spyder will enter production in 2013 ahead of a sales launch early the following year. This first convertible and somewhat production-looking version can accelerate from 0-60 mph in less than five seconds and gives 78mpg combined fuel economy. From what we hear the production i8 Spyder will feature removable carbon fiber roof panels, a transparent engine cover and rollover safety bars located behind the seats. The car has a distinctive open cockpit design with upward-swiveling windowless doors.

Both the coupe and Spyder version of the i8 supercar feature a plug-in hybrid drivetrain comprised of a turbocharged three-cylinder gasoline engine mated to an electric motor. The electric motor powers the front wheels and the engine send power to the rear. Both sources can work together to form an all-wheel drive setup. An “energy tunnel” in the center houses high-voltage lithium-ion battery. The system generates an overall output of 400 horsepower. Expect a full reveal of the i8 Concept Spyder at the 2012 Beijing Auto Show later in the month.
