Classic car EV conversion / full restoration support
A 1970 Mini EV build using a Tesla Small Drive Unit, 35 kWh battery pack and 7 kW AC charging. The project required major packaging work, drivetrain upgrades, custom shafts, braking improvements, limited-slip differential installation and careful torque mapping to make the car usable on the road.
Discuss a related projectProject introduction
Turn an unfinished classic Mini project into something far more exciting than a basic EV conversion, while still making it controllable and usable in real traffic.
Complete the EV side of the project, replace the original Nissan Leaf-based concept with a more powerful Tesla Small Drive Unit package, integrate the battery and charging systems, commission the vehicle and refine the drivetrain so it could be driven safely.

Engineering & integration
Commissioning & result
The Mini became a very fast and characterful EV restomod. Early testing showed that even a limited power output could overwhelm the original wheels and chassis setup, so the car was progressively upgraded with better brakes, wider tyres, drivetrain improvements and smoother torque delivery. The final setup offered a usable eco mode for normal driving and a stronger sport mode for more aggressive performance.
For similar programmes
This project is a useful example for clients considering high-power EV conversions in small classics. Power is only part of the build. Tyres, brakes, shafts, differential behaviour, suspension geometry and torque mapping all need to be developed together if the car is going to be enjoyable rather than simply difficult to control.
