How range is measured
It’s difficult to compare the range of various vehicles. Because there are several factors that have an impact, such as driving speed, weather, terrain, etc.
Luckily the U.S. Environmental Protection Agency (EPA) developed a set of standardized test procedures that help us compare the range of multiple electric cars. In Europe, the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) is used.
Model S range
- Long Range: 370 mi / 610 km
- Performance: 345 mi / 590 km
Model X range
- Long range: 325 mi / 505 km
- Performance: 305 mi / 485 km
Model 3 range
- Long range: 310 mi / 560 km
- Performance: 310 mi / 530 km
- Standard range plus: 240 mi / 409 km
Your mileage may vary
Your power consumption and range doesn’t always match official ratings. It’s very situational.
For example: if you’re driving short distances in sub-zero temperatures, your total range will be lower than expected. But if you drive a constant speed in relatively warm weather with very little wind, you might even exceed the EPA/WLTP range.
Tip: abetterrouteplanner.com is a great tool to simulate the effect of terrain, weather, wind, road conditions on the range of your Tesla.
The range of Tesla’s is continuously improving. To give you an idea; the first Model S could only drive 139 mi (224 km) on a single charge. That has almost tripled since 2012.
Tesla has increased the range by tweaking the hardware (better and bigger batteries, more efficient motors, etc) and by optimizing the software.
