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: estimated energy cost at the average electricity market price for United States, residential retail average, as of 17 May 2026, older than 45 days, last available value (0.162 EUR/kWh); public charging tariffs are usually higher.
- Market dataCO2: energy x grid average carbon intensity of 283 g/kWh (United States, U.S. EIA Open Data, as of 17 May 2026, older than 45 days, last available value).

The 314-kilometre drive from Houston to San Antonio, taking roughly 208 minutes, is well within the real-world range of most modern EVs, even in Houston’s hot climate, which can reduce battery efficiency due to increased air-conditioning use. The route is not cross-border, eliminating any customs or charging connector concerns. For EV drivers, the flat terrain of this Texas corridor minimizes elevation-related range drain, making the trip straightforward. However, planning a brief charging stop midway could provide a buffer against Houston’s heat-induced range loss, ensuring a stress-free arrival in San Antonio without relying on the city’s smaller charging network.
