As your source points out, the 73 mile number is an adjusted 2-Cycle number not a 5-Cycle number ("EPA regulations require the city and highway energy consumption and driving range values listed on the FE Label (window sticker) to be adjusted to more accurately reflect the energy consumption and driving range that customers can expect to achieve in the real world.")Herm wrote:I think the average speed is 48mph.. the 73 mile number is is the new 5 Cycle EPA test that includes an 80mph/high acceleration high speed cycle, a cold cycle with heater use, a hot cycle with AC use plus the original mild city and hwy cycles. The original cycles are followed after a full charge plus an overnight rest and are repeated until the car cant meet the acceleration specs, probably just above turtle, total distance is measured.
The average speed on the City Cycle is 21.2 MPH. The average speed on the Highway Cycle is 48.3 MPH. The average speed on the "High Speed" is 48.37 MPH. It lasts for ten minutes (as say compared to the City Cycle that lasts over thirty minutes). That doesn't matter though because it's not ever used. The only cycles that are run on an EV are the City and the Highway.
In any event the Leaf's EPA range will probably be overstated for the kind of driving he's looking at. Most ICE vehicles get much better MPG on the Highway Cycle than the City Cycle and the USO6 Cycle doesn't bother them that much. On the other hand the Leaf does better on the City Cycle and would do very poorly on US06. Since the adjustment factor is based on how ICE vehicles perform at US06 relative to the City Cycle, which is relatively good, applying this factor to the Leaf is going to understate the adjustment factor and overstate the range.
