Electric car manufacturers and driving range claim accuracy
Nissan is facing a public relations problem due to battery capacity loss in the Nissan Leaf, and diminished driving range. While the issue is a rapid loss of driving range for Leaf owners in hot climates, a part of the problem is that Nissan claims the Leaf has a 100 mile electric driving range, when the EPA certified driving range is 73 miles. This makes one ponder the value of truth in advertising laws, but it turns out Nissan is not the only automaker doing this.
How are the automakers who manufacture all electric or plug-in electric vehicles doing?
Chevy Volt: The EPA rates the 2013 Volt for 38 miles electric driving range, and GM advertises it with a 38 mile driving range. The Volt also has a gasoline engine that acts as a generator to recharge the battery pack.
Coda: The Coda website repeatedly says "125 miles driving range" where the EPA certified range is 88 miles. The website does have a footnote explaining that "125 miles" is by the LA4 driving cycle, and then the footnote goes on to explain how the EPA arrived at the 88 miles range number.
Ford Focus Electric: Ford doesn't say much, on its website, about the range of this electric car but in the FAQ does have a statement implying the driving range is 100 miles. The EPA certified driving range is 76 miles.
Mitsubishi i-MiEV: Mitsubishi's website says 62 mile range, and the EPA certified range is 62 miles.
