"Tesla Roadster owners have been driving electric for a couple of years now and have built up knowledge about how much energy is required for many different routes and driving scenarios. New Nissan LEAF owners could perhaps benefit from what Roadster owners have learned, especially in the near term while charging stations are few and far between.
On August 4, 2011, we did a test to answer a couple of questions:
How does energy use in a Nissan LEAF compare to a Tesla Roadster?
Does knowing how much energy a Roadster uses for a certain drive help a LEAF owner plan the charge needed for a long drive?"
