I am not sure why, but over the last month, I have gotten a lot better stealth mileage from my car. It may be the warmer temperature or maybe I am driving slower in heavier traffic, but I have actually managed to squeeze 45 miles out of the battery on several occasions, and 40+ miles pretty regularly without making any special hypermiling effort. As a result, I managed to get the most miles out of a tank of gas since I have owned the car. The actual MPG, based on the amount of gas required to refill the tank was 171.5, which is still pretty impressive considering the fact that I have a 90-mile round trip commute.



This is a pretty amazing car.

Outstanding!

There is nothing I miss about the visits to the gas station, but when I do fill'er up, it is fun to calculate my mpg for that tank and update the lifetime mpg. I really think that the method of estimating mpg on EV cars is misleading to those who haven't driven one. The reality for your last tank of gas is an impressive 171/mpg!

Last week was my first visit the gas station. The Karma took 7.6 gallons after 2294 miles since late February, when I bought the car. So that's just over 300 mpg. It could have been higher except I played around with the Sport mode quite a bit when I first got the car.

That's pretty impressive considering a 90 mile daily commute. I usually get around 40 miles on a charge, but living in Tampa we have flat terrain and warm weather.

Thanks. It is fun to keep driving past the gas stations. I could have probably gone one more commute cycle with the gas left in the tank but the "Put Your Walking Shoes on Now" warning message was starting to get annoying. :D


I don't think that the MPG error is limited to EVs. Pretty much every car I ever owned, that had a trip computer, overestimated the MPG by some amount. You would think that with super precise computer-controlled fuel injection systems, the computer can very precisely calculate how much fuel was used, and mileage is pretty easy. But it seems that cars don't measure actual fuel flow but estimate it based on pressure or by the airflow, which leads to cumulative errors.

Thanks. I do have charging available at work so I set off with a full charge in both directions but the road is far from flat, and especially going home in the evening is a net climb which takes its toll.

On some days, like today for example, I actually mange to go 45 miles door-to-door on stored electrons only, which is pretty impressive on its own, but that does not happen every day.
