Nissan LEAF

2013 Nissan Leaf may have longer driving range according to Japanese news


Information about the 2013 Nissan Leaf is beginning to leak out, with longer driving range being the most tantalizing tidbit yet.

The 2013 Nissan Leaf is slated to be built in Tennessee rather than Japan, as part of Nissan's strategy to build the Leaf on the same continent where it is sold (European Leaf's will be made in England, for example). Yesterday a Japanese news website suggests that the 2013 Leaf will have several welcome changes as well, including longer driving range.

Today's Nissan Leaf is rated for 73 miles driving range, however Leaf owners report having anywhere between 60 and 100 miles of usable range depending on how fast they drive. Actual driving range in electric cars is dramatically impacted by driving habits. This is true for gasoline cars as well, witness the effort in the 70's to lower the speed limit to reduce gasoline consumption, inspiring a famous Hagar song, but the effect is more noticeable for electric cars. This has to do with physics and the fact that it requires more energy to move at a higher speed.

If the report in SankeiBiz, a Japanese newspaper, is correct the 2013 Leaf will be certified by Japans officials with a 250 kilometer (155 mile) driving range, compared to the 200 kilometer (124 mile) certification for the 2011 and 2012 Leaf's. Japan's certification process is different than the EPA's and results in different driving range estimates than the EPA estimate. If we interpret this as a 25% improvement, this means the EPA would certify the 2013 Leaf with a 91.25 mile driving range.

This would put the 2013 Leaf ahead of other electric cars like the Coda (88 miles), Ford Focus Electric (76 miles), and Honda Fit EV (82 miles).

The range improvement is said to be a result of improved efficiency in the electric motor, and improved performance of the lithium-ion batteries.

"100,000 i-MiEV's sold worldwide"? That sounds like total sales of the 'i' car which is mostly sold in an ICE format.
