EV Conversions

Land Rover Defender 90

• Powered by a Tesla Model 3 motor delivering up to 300bhp, this Defender keeps its legendary toughness with permanent 4WD while gaining the smooth, quiet performance of electric drive.

• A dual 83kWh battery pack provides a real-world range of around 160 miles, with 75kW CCS fast charging for quick top-ups on the road and 6.6kW AC charging at home.

• Built to retain the Defender’s timeless design while future-proofing it for sustainable adventures.

1970 MK2/3 Mini

• Powered by a Tesla Model S drive unit delivering up to 250bhp, this classic Mini is reborn as a modern city EV while retaining its unmistakable character. Its 35kWh battery pack offers around 140 miles of range, making it perfect for spirited urban driving and short weekend trips.

• With front-wheel drive and 6.6kW AC charging, it blends everyday usability with performance far beyond the original — all in a compact package that still turns heads everywhere it goes.

Land Rover Defender 110

• This long-wheelbase Defender 110 was reimagined for extended adventures, powered by a 100kWh dual battery pack delivering up to 200 miles of range. A Tesla Model 3 motor (300bhp) provides smooth but powerful acceleration, while permanent 4WD ensures true off-road capability.

• Comfort and usability were a focus: cabin A/C, custom Range Rover Velar gear selector, and bespoke reverse-engineered Puma gauges integrate seamlessly. With 19.8kW 3-phase AC charging and active battery cooling, this Defender is built for long-distance touring and rugged terrain alike.

Land Rover Defender 90

• This build combines classic Defender toughness with a modern electric heart. Powered by a Tesla Model 3 motor producing up to 300bhp and paired with a 55kWh Felten battery pack, it delivers a practical balance of performance and range.

• With permanent 4WD and support for both 50kW CCS fast charging and 6.6kW AC home charging, it’s ready for daily use or weekend adventures. Offering a real-world range of around 100 miles, this Defender is ideal for shorter trips while showcasing the flexibility of EV retrofits.

Engineering Projects

Not just about EV conversions

Skyfly eVTOL Collaboration

We work closely with Skyfly to support the development of their cutting-edge eVTOL aircraft. Our expertise in electrical systems design and integration plays a key role in helping the aircraft take flight safely and reliably. From power distribution to system diagnostics, we ensure that every component meets the demands of advanced aviation technology.

Porsche 911 Targa EV Support

At VASS, we have the privilege of working on this stunning Porsche 911 Targa EV conversion, helping the owner overcome challenges they faced with their initial build. Our team applies expertise in diagnostics, electrical integration, and system optimisation to refine the car’s performance and reliability.

By carefully addressing issues in the conversion, we ensure that this iconic classic not only retains its character but also delivers the smooth, dependable driving experience expected from a modern EV.

Defender LT1 V8 Conversions

At VASS, we support customers who want more than just an EV option — delivering powerful performance upgrades where it makes sense. We have worked on several Land Rover Defender conversions, replacing the original diesel powertrain with the Chevrolet LT1 V8 engine paired to a 10-speed automatic gearbox.

This combination transforms the Defender into a modern performance machine while retaining its rugged, iconic presence. By blending advanced drivetrain engineering with precision installation, we ensure that every converted Defender offers both reliability and exhilarating power.

“Classic strength, redefined with modern muscle.”

Supporting Independent EV Projects

At VASS, we don’t just take on full conversions — we also provide specialist support for customers who are building their own EVs. This classic Mini project, self-converted by its owner, came to us for wiring loom work and electrical integration to ensure the system runs safely and reliably.

By offering tailored engineering services, we help keep unique projects like this moving forward, giving enthusiasts the confidence that their builds meet professional standards.

"From complete conversions to specialist support — we make every EV project possible.”

Twisted Defender EV Support

We had the privilege of working on this EV-converted Land Rover Defender by Twisted, after the client came to us with a charging issue. Following a full set of diagnostics, we identified the onboard charger as the root cause.

The unit was sent back to the manufacturer, who confirmed our findings. Once repaired, we reinstalled the system and successfully brought the Defender back to full health. Now, the client can once again enjoy this incredible EV conversion with confidence.

Defender TD5 Transformation

We helped to transform this Land Rover Defender TD5, upgrading it from a manual gearbox to a smooth automatic transmission for improved drivability. As part of the project, we also integrated a full Puma dashboard for a modernised interior and installed a complete air conditioning system, adding comfort to match capability.

This combination of upgrades enhances both daily usability and long-distance touring, proving that classic Defenders can be tailored to meet modern expectations without losing their rugged character.

UAE-Spec Defender EV with Custom Climate Control

This Defender EV conversion is engineered for life in the extreme heat of the UAE, featuring a one-off air conditioning system developed entirely in-house by VASS. Our bespoke controller manages both cabin comfort cooling — seamlessly integrated into the original Puma dashboard with minimal modifications — and active battery thermal management.

The system directs chilled coolant from an A/C-driven heat exchanger to the battery pack, ensuring it remains safe and efficient even in harsh desert conditions. By monitoring all key vehicle parameters in real time, our controller intelligently allocates cooling where it is most needed, optimising efficiency while protecting components.

This project demonstrates our ability to go beyond standard conversions and deliver tailored engineering solutions that meet the demands of unique environments.

Bespoke Interior Engineering

At VASS, we believe the details matter just as much as the drivetrain. For this Defender, we engineered a custom two-row centre console housing an integrated subwoofer, designed to deliver the cleanest, most precise bass possible.

This bespoke solution not only enhances the audio experience but also elevates overall cabin comfort, showing how our work goes beyond performance to create a truly refined driving environment.

“Engineering comfort, one detail at a time.”

TVR Wedge Project with ChargeheadsUK

We are actively working to bring a TVR EV conversion safely back to the road, applying our expertise in electrical systems, diagnostics, and engineering refinement. This project highlights the importance of making sure performance cars not only drive but do so reliably and safely.

For those interested in following the journey in detail, the full progress is being documented on the ChargeheadsUK YouTube channel, where you can see exactly what we are doing to make this unique build roadworthy.
