CHEVY VOLT RANGE ON ONE TANK OF GAS FULL

The honest way to describe it is to say 'Up to 40 miles without consuming gas, and then 50 miles per gallon'. 'distance per kilojoule', but most people won't have a clue Present energy efficiency in terms of a unit like Really describe their efficiency compared to a conventional gasoline-powered car using a single familiar figure. Per day - getting around 90 miles per gallon. (My commute is 24 miles each direction, leaving me with 8 miles per day running on gas so about 6 days of my commute would consume a gallon of gas that's 288 miles.) If one of my friends, who commutes 45 miles each direction per day, were to commute in a Volt, he'd end up burning a gallon of gas If I commuted in a volt, I'd get something around 288 miles per gallon. Infinite mileage according to GMs method. My wife could commute in a Volt, and never put gas in it: her commute is about 12 miles each way - so she'd effectively have The 'real' effective mileage (excluding the cost of charging the car - which will be significant!) varies depending on the length of your commute. The method that GM used to produce that mileage figure isĮxtremely dishonest and completely uninformative. But it's absolutely not what you'd expect after being told that it If you drive your car 100 miles in a day, you'll consume a bit over a gallon of gas. What if you drive your volt around the city all day? Your mileage will drop to around 50 miles per gallon once you've driven more than 40 miles. They compute it by basically saying: 'If I fully charge the car battery every night, how far will I drive the car in typical city commuting conditions before it's consumed a gallon of gas'. The 'mileage' figure, as it's presented, is really meaningless - because it's being presented for a situation in which the gasoline engine almost never runs at all.

On average, you can drive it for about 40 miles on a full charge before it needs to start using any gasoline. In city driving, the Volt is primary an electric car: it's powered by its batteries which you must recharge every night, not by gasoline. The trick is that they're playing with the definition of mileage. But GM has decided that the best way to promote it is to use bad math to tell lies to make it look even better than it really is.Ĭhevy has announced that for city driving, the Volt will get gas mileage of 230 miles per gallon. So you'd expect me to be very supportive of the hype around it, right? I wish I could. I'm honestly excited about cars like the volt - and Google helped develop the technology behind it, which biases me even more in its favor. It operates as an electric car until its batteries start to get low, and then it starts running a small gas motor to power a generator. It plugs in to your household electricity when you're home to charge its batteries. Chevy is coming out with a very cool new car, the Volt. It's yet another example of what I call a metric error: that is, the use of a measurement in a way that makes it appear to mean something very different than what it really means. I saw this myself in a link to an AP article via, and a reader sent me a link

Here's a quick bit of obnoxious bad math.
