Tesla claims the Semi is only 1/2 ton heavier than a typical tractor, not sure where you got the 8 tons figure from…
Model S cruises at approximately 300Wh/mi; Tesla is claiming 2kWh/mi (approximately 6.6x the power consumption) for the Semi.
Diesel cars are rated at approximately 35mpg and diesel semi trucks at approximately 5mpg, a similar 7x factor.
So, yes in fact as the driver of an EV with an energy meter, I do 100% believe the 2kWh/mile number.
What I'm actually skeptical of and where I believe Tesla is burying the bad numbers is with the $/cargo ton/mile rating. Carrying an extra 8 tons of battery is going to limit the types of loads where an electric semi mikes sense.
