Tesla Model Y: range, battery & charging
Tesla is keeping quiet regarding battery sizes, but every Model Y claims over 300 miles of range
| Range | Wallbox charge time | Rapid charge |
| 311 miles | N/Ahrs (0-100%, 7.4kW) | 27mins (10-80%, 175kW) |
| 387 miles | N/Ahrs (0-100%, 7.4kW) | 30mins (10-80%, 250kW) |
| 364 miles | N/Ahrs (0-100%, 7.4kW) | 30mins (10-80%, 250kW) |
Among the many technical details that Tesla doesn’t tend to disclose, precise battery size is one, but the regular Rear-Wheel Drive model is estimated at around 62.5kWh, and the Long Range models (in both Rear-Wheel Drive and All-Wheel Drive forms) at about 75kWh.
The updated Model Y makes use of those two batteries for a WLTP-rated 311 miles in standard format, with 387 miles for the Long Range Rear-Wheel Drive, and 364 miles for the Long Range All-Wheel Drive. That equates to efficiency of about 5.0mi/kWh for the base car, nearly 5.2mi/kWh for the rear-driven long range battery and 4.8mi/kWh for the all-wheel drive model.
Whether you’ll hit that kind of efficiency, and in turn those range figures, will of course depend on driving style, driving conditions, weather and more. Charging should be a little more consistent. The basic Model Y supports 175kW charging and the Long Range models up to 250kW at its Superchargers, for a 10-80% top up in all models of around half an hour. At peak charging speed though, 15 minutes can add up to 148 miles in the entry-level car, and up to 166 miles in the Long Range variants.
