Looking virtually identical to the coupe, the BMW i8 Concept Spyder features sporty styling and an advanced, plug-in hybrid powertrain.

BMW has unveiled the i8 Concept Spyder at the Beijing Motor Show in additon to the eDrive badge which will be used to designate all electric and plug-in hybrid cars from the BMW i brand in the future.

Looking virtually identical to the coupe, the spyder rides on a shortened wheelbase and features a semi-transparent hood, laser headlights and a rakish windscreen with an integrated spoiler. There's also a rear diffuser and upward opening doors.

The interior is luxuriously equipped with leather upholstery, carbon fiber trim and piano black accents. Other highlights include a digital instrument cluster and a three-dimensional iDrive display.

Power is provided by a plug-in hybrid powertrain that consists of a 131 PS (96 kW / 129 hp) electric motor and a 223 PS (164 kW / 220 hp) three-cylinder petrol engine. This gives the roadster a combined maximum output of 354 PS (260 kW / 349 hp) and 550 Nm (406 lb-ft) of torque, which enables the model to accelerate from 0-100 km/h in 5.0 seconds and hit a top speed of 250 km/h (155 mph). In terms of efficiency, the spyder averages 3 liters/100 km (94.1 mpg UK / 78.4 mpg US) and can travel up 30 kilometers (19 miles) on electricity alone.
