How we calculate
Wir zeigen unsere Mathematik.
Every figure on this website has an open calculation. Here you can see how we arrive at 585 €/kWh, 350–420 km of real range and 5-year TCO — with all assumptions. If you do not share an assumption, you can adjust it yourself in our calculators.
585 €/kWh — what exactly that is
| Komponente (T6-Konversions-Standardpaket) | Wert |
|---|---|
| MEB-Akkupaket 82 kWh (brutto, identisch ID.Buzz) | 29.500 € |
| E-Antriebs-Modul (Inverter, Motor) | 8.200 € |
| HV-Verkabelung, Sicherheitssystem | 2.400 € |
| Adapter-Strukturen (originale Aufnahmen nutzen) | 1.200 € |
| Software / VCU | 1.800 € |
| Werkstatt-Stunden (Engineering + Build) | 4.890 € |
| Total ESDI Kit + Build | 47.990 € |
| Nutzbare Akku-Kapazität | 82 kWh |
| Daraus: ESDI-Konversionspreis pro kWh | 585 € |
Vergleichswert ID.Buzz Pro: List price 68,450 € minus residual value of the T6 (typically 8,000–12,000 €) = effective outlay 56,450–60,450 € for 77 kWh of usable capacity = ~733–785 €/kWh.
We communicate 847 €/kWh as a non-binding list price per kWh, because many buyers do not offset the T6 residual value, since they would keep the T6 anyway — so the more honest comparison figure is without the residual value deduction.
Real range — how we arrive at 350–420 km
WLTP certification is a standardized procedure on a test bench at TÜV/DEKRA that costs 25,000–60,000 € per vehicle platform. We deliberately do not invest that money — sondern in transparente Real-Wert-Berechnung.
Unsere Reichweiten-Angaben basieren auf:
Akku 82 kWh brutto, ~76 kWh netto (nach SOC-Reserve von ~5 %)
Real consumption 22–25 kWh/100km (data set from our own T6 conversion builds)
Adjustment for outside temperature (–10 °C reduces range by ~15%), load, topography
This results in: approx. 350–420 km of real range under typical conditions. In the range calculator you can set the load and outside temperature yourself and see the respective range.
| Bedingung | Consumption | Range (76 kWh net) |
|---|---|---|
| Leichte Beladung, gemischtes Profil, +20 °C | 22 kWh/100km | ~345 km |
| Mittlere Beladung, Stadt + Land, +10 °C | 25 kWh/100km | ~304 km |
| Volle Beladung, Anhänger / Bergland, +10 °C | 28 kWh/100km | ~271 km |
| Mittlere Beladung, –10 °C | 28,8 kWh/100km | ~264 km |
5-year TCO — how the calculator computes it
Our TCO calculator compares three scenarios for a 5-year period:
1. Diesel-Bestandsflotte behalten (Status quo)
2. ESDI conversion to electric
3. Neukauf ID.Buzz-Flotte
Default assumptions per scenario — all adjustable in the calculator:
| Assumption | Default |
|---|---|
| Jährliche Laufleistung | 25.000 km |
| Diesel consumption | 10 L/100km |
| Diesel price | 1,75 €/L |
| Electricity consumption | 25 kWh/100km |
| Electricity price (workshop wallbox) | 0,32 €/kWh |
| AdBlue cost diesel | 200 €/Jahr |
| Maintenance diesel (oil, filter, EGR, turbo) | 1.800 €/Jahr |
| Maintenance electric (tires, brakes, AC service) | 280 €/Jahr |
| Residual value change diesel over 5 years | −40 % |
| Residual value change electric conversion over 5 years | −20 % |
| Insurance (comparable) | 1.200 €/Jahr |
In the calculator you can adjust every assumption and immediately see how the TCO changes. The default values are calculated conservatively — we do not want you to rely on marketing optimism.
What we do not claim
Kein "WLTP-zertifiziert"
We do not measure on a test bench. If your insurer or subsidy strictly requires WLTP, contact us — individual measurement possible for a surcharge.
Kein "ROI in X Monaten"
TCO advantages depend on electricity price fluctuations, diesel price and subsidy policy. We give you the mathematics — you make your forecast.
Kein "garantiert günstiger"
With very low mileage or high residual value risk, keeping a diesel can be cheaper. Our calculator shows this honestly.
How we build
Construction transparency: a maximum of two drill holes, original mounts, TÜV-compliant. Value retention through methodology.
