G.M. Puts Volt’s Mileage in City in Triple Digits
- tocomment 17y agoThat's so disingenuous to not count the cost of electricity for recharging it.
- krschultz 17y ago40 cents for 40 miles on electricity, it's in the article. Compared to $2-4 for 30 miles on the average sedan, not bad. Maybe this will finally spur Toyota to add a plug-in standard on the Prius.
- zngtk4 17y agoThat electricity cost is based on a single location. My electricity is 12.5cents per KWH, regardless of time of day. That turns into about 3 cents per mile, rather than 1 cent per mile quoted in this article.
- ynniv 17y agoClose, but not quite. The sentence right before their 40¢ a day claim, they say $2.75 per 100 miles. That works out to 82.5¢ for 30 miles, or $1.10 per 40 miles. 82.5¢ is 3 times better than the current $2.60 for a gallon of gas, but grid power is almost double the 11¢/kWh used for these calculations in some parts of the country.
- buofbouy 17y agoSimilarly my SUV does infinite miles per gallon on initial in-city mileage (only counting the 1/2 mi downhill stretch from my house)
- ynniv 17y agoNot true, idling consumes gasoline. Unless you have disabled your steering lock, and can do without power steering, headlights, AC, or brakes (not recommended :-) ), you are not getting ∞ MPG, even if your car tells you otherwise.
- ccc3 17y agoThis announcement proves two points: 1. Moving forward, MPG is not going to be a good measure of efficiency or operating cost. 2. GM is run by salespeople, not engineers.
- krschultz 17y agoIt begs the question, what is the proper measure? MP$, MPKWH? MP$ is what we really care about but it has to be adjusted for price fluctuations of power and gasoline, pretty impractical. Maybe list MPG City, MPG Highway, MPKWH Battery on the sticker.
- vaporstun 17y agoMPJ - Miles per Joule As we move toward alternative fuels, we need a fuel-independent metric.
- ccc3 17y agoAgreed. It'll have to be a measure of energy consumption per mile. Consumers will also have to develop an understanding of the relative cost of different energy sources. Maybe we rate cars in Miles/Joule and rate energy sources in Joules/$. Makes the math pretty simple.
- sp332 17y agoYou might need to add some cargo/people capacity in there. A tiny electric car will have a hard time beating a diesel MAC truck for efficiency when it's hauling a few tons :)
- kvh 17y agojust to be clear, you save as much gas moving up from a 20 mpg car to 25 mpg car as you do going from 50 mpg to 100mpg. (think in terms of gals per 100 mile)
- brown9-2 17y agoWell yeah, but in absolute terms only. Car 1: instead of needing 5 gallons you only need 4 gallons. Saved: 1 gallon (20%) Car 2: instead of needing 2 gallons you only need 1 gallon. Saved: 1 gallon (50%) But who makes comparisons like this in absolute terms? I rather save 50% than 20%, but maybe that's just me.
- Semiapies 17y agoPeople have to pay for things in absolute money. :) Not to mention that absolute savings are important when it comes to carbon reduction.

- brown9-2 17y agoThe lack of a plan on how to deal with urban customers or those who don't have a garage to park the car in (apartment dwellers) is really disconcerting. As the article says, these are the people who could benefit from this car the most.
