The Tesla Model 3 Dual motor used to use between 2.9kWh/mile and 3.5kWh/mile, worse in winter.
Paying 7.5p/kwh with Octopus this made cheap motoring, but that was last year. Things have changed.

I used maximum regenerative braking, but otherwise drove it as I drive any car.
The car had a heat pump, which was supposed to help range/economy.
