The shape at 10,000 km for PHEV

At this distance the car is almost entirely a depreciating asset. Depreciation dwarfs energy and maintenance, which makes any structure that finances only the depreciation — PCP, lease, salary sacrifice — comparatively efficient, and makes an expensive-to-buy, slow-to-depreciate car a worse idea than it looks. [1]

Cost-line weights for PHEV at 10,000 km a year A bar chart combining the powertrain’s cost-line profile with the mileage band’s, on an ordinal scale, for a plug-in hybrid car driven 10,000 km a year. Depreciation5Insurance3Energy / fuel2Maintenance2Tax & fees2Financing cost2
Powertrain and distance together. A line that is heavy for both PHEV 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 PHEV at 10,000 km

How well each financing structure fits 10,000 km a year A bar chart grading each financing structure from 1 (poorly suited) to 4 (well suited) for a driver covering 10,000 km a year.

Fit at 10,000 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 PHEV specifics at this distance

On electric miles it behaves like a small BEV; past the battery range it is a petrol car carrying a battery. Real-world studies find fleet and company PHEVs are often charged far less than assumed, so their real fuel consumption sits well above the official figure.

Makes sense for a driver with home charging whose daily distance sits inside the electric range and who takes occasional long trips — and who will actually plug it in. Makes little sense as a tax-driven company car that is never charged.

Low mileage weakens the EV energy-cost argument: the per-kilometre saving is real but small in total, so the case rests on tax treatment and the price paid, not on fuel.

The energy line of any total-cost estimate is the one you control after purchase. Home charging on an off-peak tariff and motorway rapid charging can differ several-fold per kilowatt-hour, so where you charge on long journeys moves the annual number more than the badge does. Drive Charge Eat plans stops around cheaper, reliable chargers that also have somewhere to eat.

Is a plug-in hybrid car worth it at 10,000 km a year?
Makes sense for a driver with home charging whose daily distance sits inside the electric range and who takes occasional long trips — and who will actually plug it in. Makes little sense as a tax-driven company car that is never charged. At this distance the car is almost entirely a depreciating asset.
Should I lease a plug-in hybrid car at 10,000 km a year?
A reasonable fit at this distance. Mileage caps on leases and PCP will not bind, so the cheapest allowance is fine — but the guaranteed future value assumes it, and going over changes the deal.
