Annual Mileage Forecast
Estimates use recorded journeys and calendar days, including days with no recorded mileage.
Finance Mileage Tracker
Your 4-year finance allowance and estimated overage.
Live projection from your diary · 15,000 miles/year over 4 years. Early driving patterns may change.
The live estimate uses your rolling 30-day mileage rate once 30 days are recorded; before then it uses your all-time rate. Your early new-car driving may overstate future mileage. Check your agreement for how mileage is measured.

What the numbers mean
A higher mi/kWh means more miles per unit of energy. Traffic, temperature, speed and terrain affect efficiency, so a change in regeneration setting alone doesn't establish the cause.
