This is a pretty interesting set of data - I’m less familiar with the website, so not sure what they’re testing protocol is, but this set of figures, all generated at a relatively cool 37F (2.8C) seem impressive, and also really demonstrate the impact of speed on efficiency:

I5 M60 range

81 mph test = 204 miles @ 2.5mi/kWh

56 mph test = 286 miles @ 3.5mi/kWh

37 mph test = 353 miles @ 4.3mi/kWh

There’s a cool slider that helps estimate range at different speeds and temps as well.
