Frequently Asked Questions

How long does the BMW E30 conversion process take? +

The complete BMW E30 electric conversion process takes 15 working days from start to finish. This includes initial assessment, component preparation, installation, testing, and final delivery. We maintain this timeline through our systematic approach and experienced team.

What is the expected range after conversion? +

Depending on the battery pack size selected, your converted BMW E30 will have a range of 200-350km on a single charge. The 30kWh pack provides approximately 200km, while the 45kWh pack extends range to 350km under normal driving conditions.

Can I still use the original transmission? +

Yes, we typically retain the original manual transmission, allowing you to maintain the classic driving experience. The electric motor provides instant torque, making gear changes smooth and responsive. Automatic transmission conversions are also possible upon request.

What charging options are available? +

Your converted BMW E30 will support both AC and DC charging. Standard Type 2 AC charging (up to 11kW) for home and public charging, with optional CCS DC fast charging capability (up to 50kW) for rapid charging on long trips.

Is the conversion reversible? +

While technically possible, the conversion is designed to be permanent. We preserve key original components and document all modifications. However, reversing the conversion would require significant work and cost, so we recommend committing to the electric transformation.

What warranty do you provide? +

We provide a comprehensive 3-year warranty covering all conversion components including motor, battery, controller, and installation work. Battery performance is guaranteed for 8 years with 70% capacity retention. 24/7 technical support is included.
