Smart Roadster EV

Some may still know me from my VW Polo 86C project. Have not written here for some time, but that should change now. I mothballed my Polo, sold most parts and got a Smart Roadster.

To the project:
Basis is above mentioned Smart Roadster BJ2006. The car is in good condition, no rust or similar.
Installed is a 0.7l turbo gasoline engine with 90hp in the rear. This was also the reason for choosing the vehicle: small, light, rear-wheel drive and affordable. With 810kg empty weight, the car is a flyweight for a Mercedes of this year.
Currently I drive the car with about 3.8l / 100km:

The goal, however, is to convert the car to electric drive. If one estimates the engine's energy efficiency and current consumption as the energy consumption later on, it comes to about 7-8kWh / 100km. The aerodynamics can still be improved MASSIV. A cw value of 0.3 should at least be achieved (currently 0.38). The front surface of just 1.54mē helps to achieve low air resistance.

I originally provided the components for the conversion for my Polo. Therefore, these are too big and too heavy for the Smart (Tesla S 220kW engine + BMW I3 90Ah battery). Currently I am trying to sell these. If this is successful, new components will be provided:
-Motor = EMRAX 228 or 268
Controller = in search
Gearbox = modified smart gearbox
Battery = LG CHEM 350V 17.6kWh 110kg

Will continue to report
