First previewed back in July, the BMW i8 Roadster is now being previewed in a new video as it undergoes production testing. The convertible version of BMW’s hybrid sports car is expected to debut at the Los Angeles Auto Show at the end of November.

We’ve already seen camouflaged prototypes of the i8 Roadster in the past, but this is the first time we actually get to see the car’s roof get installed. The good news is you won’t need to perform any manual labour like on a Lamborghini Aventador Roadster, as the car will get a power retractable fabric roof (with a small rear window).

The rest of video shows us the i8 Roadster’s carbon-fibre tub, aluminium frame and suspension assemblies, which are subjected to some vigorous durability tests. BMW claims a fuel consumption of just 2.0 l/100 km, a combined electricity consumption of 15/4 kWh/100 km, and a combined CO2 emissions of 46 g/km.

No confirmed details on what powertrain will be fitted to the i8 Roadster, but it will likely get the same one found in the hardtop. On the i8, a turbocharged 1.5 litre three-cylinder petrol engine works together with an electric motor to deliver a total system output of 362 hp and 570 Nm of torque.
