Nissan Qashqai 1.5 dCi → Cupra Formentor e-Hybrid: how much would you save?
If you're trading in your Nissan Qashqai 1.5 dCi for a Cupra Formentor e-Hybrid, the brochure won't tell you what you actually want to know — does the maths work, and how much faster do you get back what the PHEV cost? Here's the honest answer at UK 2026 prices, 10,000 miles a year, 60% of miles on battery.
| Annual cost | Nissan Qashqai 1.5 dCi | Cupra Formentor e-Hybrid |
|---|---|---|
| £/mile | 14.4p | 8.1p |
| 10,000 miles a year | £1,440 | £815 |
| Fuel type | diesel | petrol + grid |
What changes the answer most
- Annual miles. Higher mileage amplifies whatever the per-mile difference is. At 20,000 miles a year, double the saving (or double the loss).
- Your % on battery. 60% is a fair UK average if you charge at home overnight. People with a wallbox and short commutes regularly hit 80–90%.
- Your tariff. Off-peak EV tariffs (Octopus Go, Intelligent, OVO Charge Anytime) at ~7p/kWh are what make the maths work. On a 27p flat tariff the picture changes a lot.
