How we build

We build to preserve your vehicle's substance. 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

Position 1 — Main motor mount

Drilling at a structurally intended position. Size model-specific (typically 4–6 mm). Reinforcement via an adapter plate with the original mount.

Position 2 — HV wiring pass-through

Drilling aligned with the original tank feed-through. Double sealing against water and vibration ingress.

What stays original

Component	With many conversions by others	At ESDI
Tankaufnahme	often modified / welded off	original, newly used for the battery module
Getriebeaufnahme	often completely new	original, with adapter plate
Motoraufnahme	often modified	original, with an adapted motor mount
Frame / floor pan	often cut / welded	untouched
Body / sheet metal	often modified	untouched

TÜV individual approval — what that means in practice

Because we work without extensive cuts into the body, the TÜV individual approval is easier. The inspector sees the vehicle largely in its original condition — 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. We fully prepare every individual approval and accompany it through to the presentation.

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

savings

Wiederverkauf

Original substance is the classic value-retention standard. A restomod with a welded frame is no longer a classic.

verified

H-plate

For vehicles over 30 years old, the H registration remains possible because the substance is unchanged.

shield

Insurance

Body and structural parts remain largely in factory condition without extensive cuts — 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.

How we calculate

Methodology transparency for costs, range and TCO. Every figure with a breakdown and adjustable assumptions.
