How we build
We build reversibly. That means: a maximum of two drill holes.
Tank, transmission and engine mounts remain original. No cut cross members, no re-welded mounting points. Your car can technically be returned to its original condition. We do not offer this as a service — we simply build this way.
The two drill holes — where and why
What stays original
| Bauteil | Bei vielen Konversionen anderer | Bei ESDI |
|---|---|---|
| Tankaufnahme | oft modifiziert / abgeschweißt | original, newly used for the battery module |
| Getriebeaufnahme | often completely new | original, with adapter plate |
| Motoraufnahme | oft modifiziert | original, with an adapted motor mount |
| Frame / Bodengruppe | oft geschnitten / verschweißt | unberührt |
| Body / sheet metal | oft modifiziert | unberührt |
TÜV individual approval — what that means in practice
Because we do not cut into the body, the TÜV individual approval is easier. The inspector sees the vehicle structurally unchanged — only with a different drive in the mounts designed for it.
This shortens the TÜV appointment and reduces the risk that a conversion does not pass. So far we have successfully completed all submitted individual approvals — the exact number grows with every build.
Electric drives can be integrated into a classic combustion vehicle in two ways: by adapting the body to the motor — or by adapting the motor to the body. We do the latter.
That means more engineering per build. But it also means: your car stays the car you bought. Just with a different drive.
Why value retention through methodology matters
Wiederverkauf
Original substance is the classic value-retention standard. A restomod with a welded frame is no longer a classic.
H-plate
For vehicles over 30 years old, the H registration remains possible because the substance is unchanged.
Insurance
Body and structural parts remain in factory condition — insurers rate them lower than modified vehicles.
What this is not
We offer no commercial conversion back to combustion . Our specialization is the conversion to electric — cleanly built, documented.
If a customer wishes to convert back in the future, that is technically possible (which is exactly why we build this way), but we would calculate that individually — no fixed price, no standard service.
Reversibilität ist bei uns ein Build-Prinzip, kein Verkaufsangebot.
How we calculate
Methodology transparency for costs, range and TCO. Every figure with a breakdown and adjustable assumptions.
