Assumptions behind these numbers
- Model assumptionStart charge 100%, arrive with 15% in reserve, charge up to 80% at each stop.
- Model assumptionUsable battery: 100% of each vehicle's listed capacity (the listed capacity may be gross or net; no correction is applied).
- Model assumptionSpeed: consumption starts from each vehicle's listed real-world efficiency, times a speed factor of 1.00 (1.00 = no speed adjustment).
- Vehicle dataWeather: each vehicle uses its own hot, normal and cold factor from our vehicle data, so consumption = efficiency x 1.00 / factor. Hot is 25 °C and above, normal is 10-25 °C, cold is below 10 °C.
- Model assumptionCharging speed: average power = min(vehicle peak kW, 150 kW cap) x 0.60 taper, plus 5 min per stop.
- MethodRange, energy and cost all use the same consumption figure. Energy is measured at the battery; charging losses are not included.
- MethodCharging stops are estimated from range and the charging window. They are not verified charging stations.
- Market dataCost: not shown, because no electricity market price is available for United Kingdom.
- Market dataCO2: energy x grid average carbon intensity of 78 g/kWh (United Kingdom, uk-ngeso, as of 18 Oct 2026).

The 241-kilometre route from London to Cardiff, traversable in 187 minutes of driving time, presents a straightforward journey for electric vehicle drivers. Drivers should plan for a potential brief charging stop, particularly in winter, to account for range loss. The terrain is largely flat, limiting additional energy consumption from elevation changes, so the primary variable remains temperature-related efficiency.
