The Tesla Model S Long Range turns out to be more efficient than Standard Range

The EPA recently released the range and efficiency numbers for the latest versions of the Tesla Model S - the Long Range (≈100 kWh) and Standard Range (≈75 kWh) models, including Performance derivative in two wheel options (19- and 21-inch).

As you can see below in the full data set, the Long Range version offers the highest range 370 miles (595 km) as well as best efficiency of 304 Wh/mi (189 Wh/km) - 10% better compared to the previous 100D.

Surprisingly, the Standard Range, which we assume is equipped with a much lighter 75 kWh battery, is less efficient: 309 Wh/mi (192 Wh/km). The range is 285 miles (459 km), 23% lower than in the case of Long Range.

Of course, the Performance version is the least efficient with 345 miles (555 km) (6.8% below Long Range) of range and energy consumption of 324 Wh/mi (201 Wh/km) and it deepens if one opts for a 21-inch wheel version: 325 miles (523 km) and 347 Wh/mi (216 Wh/km). As you can see the range is 5.8% lower just because of the bigger wheels.
