BMW has taken the next step with its new roadster version of the i8 supercar, teasing the new open-top plug-in hybrid in a short video.
The clip shows the shape of the new model, although wearing camouflage, with what appears to be a cloth roof.
The outline of the cloth roof suggests that the roadster will feature a more targa-style drop-top with elements behind the seats remaining intact, similar to that seen on the Mazda MX-5 RF and Porsche 918 Spyder.
BMW has focused on the aerodynamics in the video leading us to believe the convertible roof won't compromise performance too much. Also present are the eye-catching butterfly doors from the coupe.
The Bavarian automaker hasn't revealed any information regarding performance, but it is expected to have the same 1.5-litre turbocharged three-cylinder petrol engine and the electric motor, which combine for 266kW and 570Nm, from the standard i8.
However, BMW has stated that they have shaved 0.1L/100km off the claimed fuel use, bringing the figure to a flat 2.0L/100km for the roadster, which would suggest BMW has cut the weight of the roadster version.
Look to the upcoming 2017 Frankfurt Motor Show in September for the potential reveal, with a production version due in 2018.
