Current RealTCO v5.0 comparison: Mazda 6e 68.8 and alternatives

This article has been recalculated from verified vehicle inputs. Under the common reference scenario, Mazda 6e 68.8 has the lowest five-year ownership cost at 163 663 PLN, or 2 728 PLN per month. Every TCO figure below comes from the application RealTCO v5.0 engine.

One scenario for every vehicle

The calculation assumes a new vehicle in Poland, cash purchase, 15,000 kilometres per year and five years of ownership. The road mix is 40 percent city, 35 percent local roads and 25 percent motorway. The driver has a garage, a home charger and a dynamic electricity tariff. Financing and purchase subsidies are excluded. Petrol is set to 6.50 PLN per litre, diesel to 6.80 PLN and LPG to 3.20 PLN. These assumptions make the comparison reproducible, but they are not a quote for every driver.

RealTCO v5.0 results

Net TCO is not the same as all cash paid before resale. The engine adds purchase and operating expenditure, then subtracts the projected value of the vehicle at the end of year five. The monthly number is exactly net TCO divided by 60 months. Cost per kilometre uses the same net result divided by 75,000 kilometres. This prevents a common error where total expenditure is called TCO while the monthly figure is calculated from a different base.

How to interpret the ranking

Depreciation is usually the largest and least certain component. The residual value is a model estimate, not a guaranteed buy-back offer. A future transaction will depend on mileage, condition, accident history, battery health, market supply and changes in new-car prices. A small difference between two vehicles should therefore be treated as a scenario result, not as a promise. The table is most useful when it shows which cost category creates the gap and how large the gap is relative to total ownership cost.

Energy and fuel costs use the same annual mileage and road split for every column. Service, repair risk, insurance and tyres are also generated by the application engine. No hand-written monthly lease instalment, guessed promotion or foreign-market price is used as TCO. If a manufacturer changes a Polish list price or replaces a model year, the vehicle record must be updated and the engine run again before the article is republished.

Why verified inputs matter

A model name alone is not enough. Battery size, drivetrain, trim, model year and price must describe the same vehicle. Mixing the price of a base version with the battery of a higher trim can move depreciation and energy costs in opposite directions. For a used car, the price must be identified as a market snapshot. For a plug-in hybrid, fuel consumption after the battery is depleted is essential. If a Polish price or a required technical input is missing, the responsible result is no TCO.

What can change your result

Higher annual mileage gives energy, tyres and servicing more weight. Public rapid charging can materially raise an electric vehicle's energy bill. Credit, leasing and long-term rental add interest, fees and contract limits that are absent from this cash scenario. Insurance varies by driver and postcode. Ownership duration also matters because early depreciation is not linear. Users should rerun the calculator with their actual mileage, charging access, financing and intended holding period before making a purchase decision.

Conclusion

For the stated reference case, Mazda 6e 68.8 is the lowest-cost option among the vehicles shown. The result answers a cost question only. It does not score comfort, charging convenience, luggage space, performance or dealer support.
