EV Engineering Services
Focused support for conversions, prototypes and specialist vehicles—from one defined fault to a complete integration package.
Discuss an engineering requirementDefined scope
Bring the project at its current stage
VASS supports private clients, workshops and development teams. Start with the vehicle, the work already completed and the outcome needed; the engineering scope can then stay proportionate.
EV Conversion Support
Technical help for part-built conversions, workshop projects and vehicles that need a clear route to completion.
