Range Rover Sport 3.0 SDV6 → Audi A3 40 TFSI e: how much would you save?
If you're trading in your Range Rover Sport 3.0 SDV6 for a Audi A3 40 TFSI e, 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 | Range Rover Sport 3.0 SDV6 | Audi A3 40 TFSI e |
|---|---|---|
| £/mile | 30.5p | 7.4p |
| 10,000 miles a year | £3,053 | £743 |
| 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.
