Careful with the numbers. With hybrids, they often don't count the electricitiy in the consumption, but still measure with the car running on it. That leads to these rather outrageous numbers of 261MPG - they just assume electricity is free. Using that measurement, of course the Tesla Model S has infinite MPG.
- sageikosa 13y agoTesla Model S would have an undefined MPG. The limit approaches infinity for very small values of G, but isn't defined for a value of 0.
- kristianp 13y agoThey assume electricity is 'free', because the battery is charged only by the fuel in a hybrid. (Not a plug-in hybrid of course). So there is no need to consider the electricity as a separate cost. Or am I misunderstanding what you're saying?
- revelation 13y agoMost hybrids with a larger battery (as this one) also have a charging port. I think what they do is start the test with a fully charged battery and never count the energy in that. So you get the first 40 miles or so free until the motor kicks in to recharge the battery again (which is where they then start counting the gasoline consumed).
