The Honda Prologue consumes around 26.3 kWh per 100 km in real-world use. Charging 80% at home (0.35 €/kWh) and 20% at public DC stations (0.55 €/kWh) works out to €10 per 100 km. Over 15,000 km a year that is about €1,539 in electricity. The 85 kWh usable battery delivers 476 km WLTP range; in winter plan for around 343 km between charges.

Over 15,000 km/year, the Honda Prologue saves roughly €299 vs an equivalent petrol car.
Charging the Honda Prologue mostly at home costs roughly €1,381 a year; relying entirely on public DC stations would be about €2,170. A home wallbox is the single biggest lever on running cost.

After 10 years the EV saves about €2,985 in energy costs.

The EV emits roughly 38% less CO₂ — 937 kg saved per year.
Using the German grid mix (380 g CO₂/kWh), the Honda Prologue sits about 38% below an equivalent petrol car — roughly 4,685 kg less CO₂ over 5 years. On a green tariff or home solar it falls further toward zero.
Winter penalty: ~28 % vs WLTP (ADAC and Spritmonitor comparative data).

Take real-world consumption
We use a year-round real-world figure (~26.3 kWh/100 km, the mean of summer and winter telemetry from ADAC Ecotest and EV-Database) instead of the WLTP headline (21.4 kWh/100 km). In winter we model 29.5 kWh/100 km separately.
Weight the electricity price
Defaults: 80 % home (€0.35/kWh) and 20 % DC fast (€0.55/kWh). Adjustable in the calculator.
Compute cost per 100 km
kWh/100 km × blended €/kWh = cost per 100 km.
Scale to annual mileage
Default 15,000 km/year: cost/100 km × 150 = annual energy cost.
Add 5-year TCO components
Depreciation 45 % (€0), insurance €0, maintenance €500/year, energy €7,693.
At 80 % home charging (€0.35/kWh) and 20 % DC fast-charging (€0.55/kWh) with a real-world consumption of 26.3 kWh/100 km, the Honda Prologue runs at about €10 per 100 km.
WLTP lists 476 km. In realistic winter conditions (−5 °C, motorway, heater on) a practical figure is 343 km — roughly 28 % below the homologated number.
A 10 → 80 % top-up on the 85 kWh battery takes about 6h 5m on an 11-kW AC wallbox.
With a DC peak of 150 kW, a 10 → 80 % session takes roughly 35 minutes at a high-power charger.
At 15,000 km/year, 80 % home-charging, and average insurance and maintenance, 5-year TCO lands around €10,193 — including depreciation.
A petrol equivalent at 7 L/100 km and €1.75/L runs €12.25 per 100 km — about €2 more than the Honda Prologue. Over 15,000 km a year, the EV saves roughly €299.
On the German grid mix (380 g CO₂/kWh) the Honda Prologue emits about 1,499 kg CO₂ a year, versus roughly 2,436 kg for an equivalent petrol car — 38% lower, or 937 kg saved. Over 5 years that is about 4,685 kg.
Filling the 85 kWh battery on a home wallbox (€0.35/kWh) costs about €30 — good for roughly 476 km WLTP, or 343 km in winter.
At 15,000 km a year with 80% home charging, the Honda Prologue's energy cost over 10 years is around €2,985 less than a petrol car's (7 L/100 km at €1.75/L) — before counting depreciation and maintenance.
Core formula: consumption (kWh/100 km) × blended €/kWh = cost per 100 km. Depreciation 45 % over 5 years, insurance 4 % of MSRP/yr, maintenance €500/yr (EV average). CO₂ comparison: German grid mix 380 g CO₂/kWh (Umweltbundesamt, 2023) for the EV and 2.32 kg CO₂ per litre of petrol for the combustion car — use-phase in both cases. Per-model sources:
