70D is less efficient on the HWY compared to 85D?

    according the this website:

    Gas Mileage of 2015 Tesla Model S

    The 70D is worst on the highway but better in the city. I though because the 70D is a lighter car, it should excel in BOTH highway and city. What is going on here? Any opinion?

    Also it seems like the P85D is actually more efficient than the S85 or P85, yet its EPA is worst? 255 vs 265? This might make sense because I heard the EPA changed their way of measuring range compared to the old method. But then why would mpge be higher, yet overall range is lowered if the battery capacity is the same?

    The chart is in kWh/100 miles. In that case a lower number is better. I think the chart shows that the 70D is the best and not the worst in terms of efficiency.

    Oops that was for city only. Yes you are right that is strange.
