The headline answer in one paragraph
In 2026, a clean Gen 4 Prius from 2018 with 150,000 PCO miles and a live plate typically trades to a specialist buyer for £9,000 to £11,500. An equivalent-age, equivalent-mileage Corolla Hybrid Touring Sports or hatchback typically trades for £8,500 to £11,000. The Corolla is fractionally weaker on absolute trade value at the same point in life, but it depreciates slightly slower from year 4 onwards, which means a Corolla bought new in 2020 and sold in 2026 has lost a smaller percentage of its purchase price than a 2020 Prius sold in 2026. The two answers are not the same; the right comparison depends on whether you are buying or selling and on your time horizon.
Why their depreciation curves differ
The Prius and the Corolla Hybrid share a hybrid powertrain (Toyota Hybrid System II / 1.8 litre Atkinson-cycle petrol with electric assist) but they trade in slightly different markets, and the resale curve reflects the differences in demand.
The Prius is purpose-built for taxi service: angular five-door body, large boot, low load floor, panoramic visibility, generous rear-seat legroom. The licensed-trade buyer network buys Priuses for licensed-trade resale almost exclusively; the second-hand domestic-retail demand for a used Prius is comparatively thin (most private buyers prefer something less obviously taxi-coded). This narrow buyer base means trade values are tightly bunched and reflect the licensed-trade demand cycle.
The Corolla Hybrid is a mainstream Toyota family car that happens to also work well as a PHV. It has both the licensed-trade buyer demand and a healthy private-retail buyer demand, which means trade values reflect a wider buyer pool. Practical effect: Corolla resale prices are less volatile across the licensing-cycle (less affected when a wave of older PCO Priuses hits the trade together), and the underlying depreciation curve is shallower because the addressable resale market is broader.
The two effects roughly net out at age 3 to 4 years (when both vehicles are still well within their licensable window), but diverge from year 5 onwards as the Corolla's broader buyer base supports value better than the Prius's narrower one.
Trade values by generation in 2026
Realistic specialist trade pricing for clean, full-history PCO Priuses and Corollas in 2026:
- Gen 3 Prius (2010 to 2015), 180,000 to 280,000 miles, live plate: £2,800 to £5,800.
- Gen 4 Prius (2016 to 2022), 100,000 to 200,000 miles, live plate: £8,000 to £14,000.
- Gen 4 Plug-in Prius (PHV variant, 2017 onwards), 80,000 to 160,000 miles, live plate: £10,500 to £16,500. Premium for the larger battery + lower running costs.
- Gen 5 Prius (2023+, plug-in only in UK), 30,000 to 80,000 miles, live plate: £18,000 to £24,000.
- Corolla Hybrid hatch (2019+), 80,000 to 180,000 miles, live plate: £8,500 to £15,000.
- Corolla Hybrid Touring Sports (estate, 2019+), 80,000 to 180,000 miles, live plate: £9,000 to £15,500. Slight premium over hatch for the larger load capacity.
- Corolla Hybrid saloon (2019+, where available), 80,000 to 180,000 miles, live plate: £8,000 to £14,000. The saloon is the rarest Corolla body style in the UK and trades slightly behind the hatch.
Resale levers that differ between the two
Three levers behave differently on the two cars at point of sale:
- Body style choice. The Prius has effectively one body (the five-door hatch); the Corolla has three (hatch, Touring Sports estate, saloon). Body style affects Corolla resale by £400 to £900 in either direction. The Touring Sports holds a small premium because the broader load capacity expands the licensed-trade buyer base into pet-transport, airport-run, and small-fleet PHV use cases that the hatch cannot serve.
- Battery type and warranty. Gen 4 Priuses came with both NiMH and Li-ion batteries depending on trim and year; Corollas are NiMH only across the line. Both packs are durable, but the Li-ion-equipped Gen 4 Priuses command a £300 to £600 trade premium because the cells age slightly more predictably than NiMH at high mileage. Toyota's extended hybrid battery warranty (10 years or 100,000 miles depending on dealer programme) covers both cars and is transferable; an in-warranty pack is worth £400 to £700 on resale either way.
- Trim level economics. The Prius has fewer trim levels (Business Edition Plus, Excel, in the Gen 4 era) and the trade does not price big differences between them. The Corolla has more trim variants (Icon, Icon Tech, Design, Excel, GR Sport in some years) and the trade values them in a wider spread: an Excel Corolla Touring Sports trades around £600 to £1,200 above a base Icon equivalent at the same age and mileage. Selection at purchase matters more for Corolla resale than for Prius resale.
Which has the better total cost of ownership for an owner-driver?
Total cost of ownership (TCO) factors in purchase price, depreciation, fuel, insurance, servicing, tyres, and the residual value at end of ownership. For a typical owner-driver running 30,000 PHV miles per year over a 4-year ownership period:
Prius: marginally better fuel economy (real-world 58 to 65 mpg vs Corolla's 55 to 62 mpg). Marginally cheaper insurance band. Marginally cheaper purchase price for equivalent-age second-hand examples. Steeper depreciation in years 4 to 6. Net: lower year-by-year operating cost, higher loss on the asset at exit.
Corolla Hybrid: marginally worse fuel economy (a few mpg behind the Prius). Marginally higher insurance band on some trims. Higher purchase price for equivalent-age second-hand examples. Shallower depreciation in years 4 to 6. Net: slightly higher year-by-year operating cost, lower loss on the asset at exit.
The two TCO figures end up within £500 to £1,500 of each other over a 4-year ownership cycle for a typical owner-driver. The choice between them is rarely decisive on cost grounds alone; it usually comes down to body-style preference (some drivers strongly prefer the estate Corolla for boot space; others prefer the higher driving position in the Prius), passenger comfort feedback (Prius rear legroom is generous; Corolla saloon is comparable, hatch slightly tighter), and trim-level availability in the second-hand market on the day you buy.
The practical takeaway
For a driver buying second-hand in 2026 with a 3 to 5 year ownership plan, the Corolla Hybrid Touring Sports gives the marginally better resale economics and the broader practical use. For a driver who already owns a Prius and is deciding when to sell, the trade values are competitive with what they would have been a year ago; there is no urgent reason to act on a Prius solely because of perceived Corolla competition.
