While I agree about the times, the efficiencies do vary.
The Volt gets just over 3 miles/Kwh
The Tesla gets about 4 miles/Kwh
Not sure about the Leaf
I guess I need to ask you to show your work
Sure, they vary, but not by much.
There are various numbers published for range and charge times, it depends upon conditions, but from wiki I found:
The VOLT: The EPA found in tests using varying driving conditions and climate controls, the all-electric range averaged 35 miles....
According to General Motors a full charge takes approximately eight hours from a standard North American 120 V, 15 A household outlet...
The Prius Plug-in: The Prius plug-in total all-electric range is 13 mi... and 3 hour charge time.
For the LEAF, I only found a vague reference to ~ 5 miles per hour of charge, but I doubt they have any magic mojo that the others do not, so I'll assume the conditions are not exact.
Tesla is 221 Miles on a 48 Hour charge per wiki.
VOLT: 35/8 = 4.375 Miles/HC |
Prius PI: 13/3 = 4.333 Miles/HC |
Tesla: 221/48 = 4.604 Miles/HC |
I'd bet the Tesla has a better weight ratio being a two seater and better aerodynamics that would account for a 6% better ratio.
I'd assume they are all drawing the same max rated current from that plug, so efficiencies ought to match.
