So, over in this thread (http://myimiev.com/forum/viewtopic.php?f=19&t=1732) Don posted information about the published EPA estimates for our i-MiEVs:
City: 126 MPGe / Highway: 99 MPGe = Average: 112 MPGe
Also, the calculation for the EPA's estimated "real world" range:
55% City / 45% Highway = 62 mile range
EPA LA4 (mostly stop & go city driving) = 98 mile range
Here are two questions I have regarding this data:
1. If the EPA is going to calculate the "real world" range of 62 miles based on a 55 city/45 highway split, shouldn't they use the same split to calculate the average MPGe instead of just using the mean average? Therefore, the "real world" average MPGe should be: (55% * 126 MPGe) + (45% * 99 MPGe) = 113.85 Avg. MPGe.
2. I just got out of a capital planning budget meeting at work, and my accountant brain is dazed and confused with numbers and calculations at the moment. What variable am I missing in calculating the EPA's "real world" range of 62 miles based on 55% city / 45% highway? I assume it must have something to do with the battery capacity, right? I want to try and figure out my anticipated "real world" range if my daily commute is roughly 80% city stop & go driving and 20% highway driving.
