Numbers may not lie, but they sure do get confusing at times. Today'
example, the estimated updated energy efficiency numbers for th
just-released 2013 Nissan Leaf. The 2012 Leaf was rated at 99 MPG
combined, 106 city and 92 highway with a 73-mile range. The 2013 mode
gets 130 in the city, 102 on the highway and has a 75 mile range
Sounds like quite the improvement, right
The issue is that the EPA has a new testing methodology for plug-i
vehicles, an
Travis Parman, director of corporate communications for Nissan of th
Americas, said, "this new EPA testing methodology means this i
not an apples-to-apples comparison.
What it all boils down to is that the 2013 Leaf has two chargin
modes: the default "100-percent Long Distance Mode" tha
maximizes range and an optional "80-percent Long Life Mode
that Nissan says will optimize long-term battery health. The EPA test
which is being used for the first time on the 2013 Leaf, blends thes
two modes. Previously, EPA range estimates were always based o
100-percent charges, whether the cars had another charging mode o
not
If the old EPA test (i.e., 100-percent charge) had been used on th
2013 Leaf, Parman said, the result would have been 84 miles. Th
increase is due to, "refinements made to the MY13 Leaf'
regenerative braking system, reduction in vehicle weight and enhance
aerodynamics," Parman wrote. The EPA's estimated, non-blende
range estimate for an 80-percent charge is 66 miles. Parman sai
official EPA numbers should arrive in early March
