Misleading and incorrect[edit]

This graph is misleading - the numbers reported show two different values: battery-to-wheel efficiency, and plug-to-wheel efficiency. This graph treats them as one and the same, which is incorrect. I'm taking this off tesla's page.

I've uploaded a new version that corrects the March '07 number to use the plug-to-wheel value of 155 Wh/km instead of the incorrect, battery-to-wheel value of 133 Wh/km. All of the numbers should now be plug-to-wheel as originally intended. Thanks for catching that mistake. sn‾uǝɹɹɐʍɯ (talk) 23:59, 12 March 2009 (UTC)[reply]

Where's the temperature?[edit]

Also, isn't battery charge affected by ambient temperature, or has tesla solved this problem? It would be nice to see how that's affecting this curve. —Preceding unsigned comment added by 74.7.165.65 (talk) 16:35, 25 November 2009 (UTC)[reply]
