The shape at 20,000 km for ICE

The reference case most quotes are built around. Depreciation still leads, energy is now a clear second, and most structures fit — which is exactly why comparisons at this mileage look flatter than they are at either extreme. [1]

Cost-line weights for ICE at 20,000 km a year A bar chart combining the powertrain’s cost-line profile with the mileage band’s, on an ordinal scale, for a petrol car driven 20,000 km a year. Depreciation4Energy / fuel4Insurance3Maintenance3Tax & fees3Financing cost2
Powertrain and distance together. A line that is heavy for both ICE and this mileage is the one this driver should decide on. Ordinal combination consistent with the total-cost-of-ownership literature cited on this page.

Which way to pay fits ICE at 20,000 km

How well each financing structure fits 20,000 km a year A bar chart grading each financing structure from 1 (poorly suited) to 4 (well suited) for a driver covering 20,000 km a year.

Fit at 20,000 km a year. Structures with a mileage cap — lease, PCP, subscription — fall away as distance rises; outright ownership climbs. This is the comparison the monthly figure hides. Grading: our reading of how each structure’s terms behave with distance, not a formal assessment.

The ICE specifics at this distance

One line, one price, rising in step with distance. No cheap-tariff option exists.

Still competitive at low mileage, where energy barely matters and the lower purchase price dominates. Loses ground steadily as distance rises and as tax regimes tighten.

Compare

Is a petrol car worth it at 20,000 km a year?
Still competitive at low mileage, where energy barely matters and the lower purchase price dominates. Loses ground steadily as distance rises and as tax regimes tighten. The reference case most quotes are built around.
Should I lease a petrol car at 20,000 km a year?
A reasonable fit at this distance. Standard lease and PCP allowances are pitched around this band; specify the real annual figure rather than accepting the default, because it is the default that generates excess charges.
