JC08 Numbers - Prime Electric Consumption & Capacity

Using the numbers supplied by TMC using the JC08 testing (yes it's optimistic but we can gleam some useful information from it)


Official Japanese AER: 68.2km
Ministry of Land, Infrastructure & Transport Consumption Rate: 10.54km / kWh (8.65km / kWh with 17" alloys)

68.2 is the maximum number so applying that to 10.54km/kWh, we get a capacity of 6.47 kWh. That's fairly close to the 6.1 to 6.3kWh that U.S. owners are saying they're seeing on their meter for a full charge.

This also means the AER for vehicles with 17" alloys is 56km or an 18% reduction.

So, if TMNA were to give us the option of the 17" wheels, and I just apply the straight 18% reduction, we'd see an EPA estimate of 20.5 miles or 32.8 km.

Err, wouldn't it be part of the fuel consumption test?

e.g. the Prime is rated at 6.3km/kWh (133MPGe = 3.95 mi/kWh)

Using the EPA's numbers (25 miles and 3.95mi/kWh), the capacity is 6.33kWh

 

1 gallon of E0 gasoline is ~33.670kWh

So 6.5*33.670 = 219 mpge.

 

Huh. Ok. But still doesn't account for 60% increase.

That's still pretty good numbers. Where does the Prime show the miles/kWh consumption? In the MID?

 

Thanks !
