Full EV conversion / bespoke systems integration
A highly integrated Puma Defender EV conversion built around a 100 kWh Tesla Model S/X battery pack, Tesla Model 3 motor kit, OEM-style gear selector, reverse-engineered Defender gauges and active cabin and battery cooling for hot-climate use.
Discuss a related projectProject introduction
Create a left-hand-drive electric Defender suitable for UAE conditions, with the performance and usability of a modern EV while retaining the character of the original vehicle. The conversion needed to feel complete rather than like a collection of aftermarket EV parts.
Electrify the vehicle, integrate a large OEM EV battery pack, uprate the drivetrain, retain a high-quality cabin experience, develop OEM-style driver controls and engineer a cooling system capable of supporting cabin comfort and battery temperature control in extreme heat.

Commissioning & result
The vehicle became one of the most complete and factory-feeling EV Defender projects VASS worked on. The EV drivetrain, selector, gauges, cabin AC and active battery cooling were developed into a coherent system, then tested in a 50 C heat-soak environment to prove the cooling strategy under difficult static conditions.
For similar programmes
This project shows what is possible when a classic Defender EV conversion is treated as a complete vehicle engineering project. It is relevant for clients who want more than a basic electric drivetrain: hot-climate use, OEM-style controls, battery cooling, proper diagnostics and a conversion that feels integrated from the driver’s seat.
