[USMA:45700] Re: Wh/mile vs J/km

[Jason D Darfus]

Sounds good to me. A while ago I calculated the energy consumption of my diesel VW Jetta versus my all electric Vectrix VX-1 scooter: diesel car that sips 4.7 L / 100 km @ 36.4 MJ / L energy content = 1700 kJ / km

electric scooter using 5 kW•h (18 MJ) over 60 km range = 300 kJ / km

In addition I've sent feedback to GM expressing the desire to see the Volt use this approach.

Dear Metricators:



    Here's a chance for USMA and others to promote and use of the SI.

    What do you think?

Use J/km rather than Wh/mi as some news media are beginning to use.
