What these numbers mean
After applying the no purchase subsidy, the 2026 Tesla Model Y has a net purchase cost of £42,990 versus £36,385 for the 2026 Toyota RAV4. That leaves a net price gap of £6,605 in the petrol vehicle's favour at the point of purchase. Every miles driven after that works to close — or extend — the gap depending on local energy costs.
At UK average electricity (£0.245/kWh) and petrol (£1.40/litre), the per-mile fuel cost breakdown is:
- Model Y (electric): 6.4¢/mile
- RAV4 (44 mpg UK): 14.5¢/mile
- Fuel saving per mile: 8.1¢ in the EV's favour
- Annual fuel saving at 12,000 miles: £968/year
At UK average energy prices, the £6,605 net price gap translates to a break-even of roughly 6.8 years at 12,000 miles/year. Local electricity and petrol prices shift this — the five-region table above shows territory-specific figures.

UK incentives: does the Tesla Model Y qualify?
The UK removed the Plug-in Car Grant for private buyers in 2022. The main financial benefits now are: the OZEV EV Chargepoint Grant (up to £350 towards home charger installation for eligible households), company car BIK at 2% for zero-emission vehicles versus 25–37% for petrol/diesel (an enormous saving for business users), and zero VED (Vehicle Excise Duty) in the first year. From April 2025, EVs pay a standard VED rate but remain significantly cheaper to tax than combustion vehicles.
In London, EVs are exempt from the Congestion Charge (£15/day) — worth up to £3,900/year for five-day-a-week commuters — and from the Ultra Low Emission Zone (ULEZ) charge. Scotland operates the EV Loan scheme through Energy Saving Trust, offering interest-free loans up to £30,000.

Battery warranty
The 2026 Tesla Model Y carries a battery and drive-system warranty of 8 years / 99,418 miles, covering the 57.5 kWh pack. The warranty typically guarantees at least 70% usable capacity retention within that window. At 12,000 miles/year, the distance warranty covers approximately 8 years of driving.
Real-world battery degradation studies show most EVs retain 88–92% capacity after 100,000 miles under typical charging conditions. Factors that accelerate degradation: frequent DC fast charging to 100%, sustained high-heat environments without thermal management, and long periods of storage at high or low states of charge.
Range, charging, and real-world use
The EPA-rated range is 283 mi. In practice, real-world range varies by speed, temperature, HVAC load, and driving style — expect 80–90% of the official figure under typical mixed conditions. At 12,000 miles/year and an effective range of 241 miles per charge, you'd need roughly 50 full charges annually.
Home 7 kW (11 kW three-phase in the UK) charges the 57.5 kWh pack from 20% to 100% in approximately 8.0 hours — overnight charging covers any realistic commute. 3-pin 13A charging adds roughly 4–8 miles/hour (UK). DC fast charging (50–350 kW depending on charger and vehicle capability) can add 100+ miles in 20–30 minutes at a public network, but at premium per-kWh rates is significantly more expensive than home charging.
The break-even table above assumes 80% home charging at residential rate. If your charging profile differs — for example, no home charger — re-run the calculation in the charging cost calculator.
Who should consider the Model Y?
The case for switching: Commuters and suburban drivers covering 10,000–20,000 miles/year. The crossover segment is where EV economics are strongest: enough body size to absorb the battery cost premium, and enough typical mileage to amortise it quickly. At 8.07¢/miles in fuel savings and £968/year at 12,000 miles, the maths compounds clearly.
The case for staying with the RAV4: Occasional drivers covering fewer than 6,000 miles/year. Also buyers with no home charging — entirely public charging substantially narrows the per-miles advantage.
The break-even maths are clearest for drivers who cover 10,000+ miles/year with access to home charging. If your annual distance is closer to 5,000–6,000 miles, run the calculator at your exact figure to see whether the EV's economics still close within a 5–7 year ownership window you find acceptable.

What government incentives are available for the Tesla Model Y in UK?
The UK removed the Plug-in Car Grant for private buyers in 2022.

How much faster does break-even happen at higher annual miles?
At 20,000 miles/year, annual fuel savings reach $1,614 — roughly 67% faster payback than at 12,000 miles. At 6,000 miles/year savings drop to $484 and the break-even period doubles. Run the break-even calculator with your actual mileage for a personalised figure.
What if I charge mostly at public fast-charging stations?
Public rapid chargers in the UK typically charge £0.65–0.85/kWh — roughly 3× the home rate. At £0.75/kWh, the Model Y costs approximately 19.6p/mile. The table above assumes approximately 80% home charging. Use the charging cost calculator to model your exact mix.
Does the battery warranty cover capacity loss?
Most manufacturers guarantee capacity will not fall below 70% within the 8-year / 99,418-mile term. Real-world data shows most batteries retain 85–90% capacity after 100,000 miles with typical charging habits — avoid frequent fast charging to 100%, keep daily charge between 20–80%, and park out of sustained extreme heat.
How does maintenance cost compare between the Model Y and the RAV4?
EVs skip oil changes, spark plugs, exhaust service, and most brake wear — regenerative braking handles the vast majority of deceleration. They still need cabin air filters, tyre rotations (EVs are heavier and can wear tyres faster), brake fluid every 2–3 years, and 12V battery replacement every 5–8 years. The net maintenance advantage is typically £400–£800/year in the EV's favour. We exclude this from break-even because individual variance is high, but it adds meaningfully to the EV's total ownership advantage over time.
What if petrol prices fall substantially?
Each 10p/litre drop in petrol reduces annual fuel savings by roughly £124 at 12,000 miles/year. Even at 110p/litre petrol, the per-mile electricity advantage persists at current UK residential tariffs.
