I was off-line for the last day or two so I'm just catching up now. I know my post says these MPGe numbers are for a P90D but I shifted Model numbers a couple times while looking up the quoted estimates and thought Ihad settled on using 90D rather than P90D. I'm too lazy now to go back and verify exactly which Model S version the MPGe Tesla numbers are for. Either way, the bottom line is that the Model S scores unusually low City MPGe numbers using CR's test methodology vs EPA. CR is generally harsher on city estimates than EPA but the Model S exaggerates this effect even more.@Jeff N posted a sample of the P90D which is rated 64 MPGe under CR's city cycle vs 102 MPGe on EPA city, so the city test does skew very poor for Teslas (probably what you mentioned, extra acceleration and less chance for regen).
True, although I loosely repeated their test while driving in the CA Central Valley with no visible wind on CA-99 at an average speed of 74 mph (CC set to 76 mph with occasional brief and mild slowdowns during almost 100 miles). Subsequently someone looked up weather records online which indicated I could have had a 3-4 mph tailwind. Or not. I had my A/C set to 73F as I recall and it was around 90F outside. When adjusted for around 58 kWh of battery energy I was on track to get around 190 miles of range which roughly validates their claim.How useless is it to tell us the temperature that the AC is set at? Temperature difference is what matters.
