I don't get how the 60D rated range could be 200 miles. If the Wh/miles is the same as the 75D (same motors and same battery only limited by software so I would imagine same weight) which is 316 Wh/miles (75 kwh/316 Wh/miles = 237 miles) then the 60D would have a max range of 60kWh/316Wh/mil= 189 miles. The math does not work out the advertised 200 miles. BTW when the 70D was available in the design studio the rated range was 220 miles that works out if you do 70kWh/316Wh/mil = 221 miles. Not sure what is going on with the 60D, maybe smaller and more efficient motors.
