I've seen this shared a few times... and I'm not sure I get why.
I think driving range is an important metric for fully-electric vehicles since recharging isn't easy everywhere in the country.
Otherwise I think MPG is the right metric.
Not sure why driving range of a HYBRID would be a relevant metric, that would be a factor of a lot of things, like gas tank size, which doesn't pertain to efficiency/environmentalism.
- skybrian 2y agoGallons per hundred miles would be a better metric, since it would make it clearer that improving gas mileage of inefficient vehicles makes a lot more difference for gas consumption.
- mikeyouse 2y agoMy favorite demonstration of this is that increasing your mileage from 10mpg to 12mpg, from 20mpg to 30mpg, and from 60mpg to 1,000mpg all save the same amount of gas.
- wackget 2y agoHow does that work? Can you clarify?
- skybrian 2y agoYou can’t save more gasoline than you’re using. More: The misleading, wasteful way we measure gas mileage, explained https://www.vox.com/future-perfect/350382/gas-mileage-fuel-economy-mpg-gphm-gas-guzzlers https://www.vox.com/future-perfect/350382/gas-mileage-fuel-e...
- mikeyouse 2y agoTo travel 100 miles at each of those MPGs; 10MPG = 10 gallons of gas 12MPG = 8.33 gallons of gas 20mpg = 5 gallons of gas 30mpg = 3.33 gallons of gas 60mpg = 1.67 gallons of gas 1,000mpg = 0.1 gallons of gas So moving from 10-12mpg saves 1.67 gallons per hundred miles. Moving from 20-30mpg saves the same. At 60mpg, you're only using 1.67 gallons of gas, so there's no improvement to MPG that will save more than that. Nearly all the gains to actual fuel consumed will come from increasing the worst offenders rather than e.g. trading in Corollas for Pruises. Also a good demonstration why the CAFE standards and other government fleet minimums are actually pretty effective at lowering fuel demand.
- throwaway4good 2y agoIt has a 65 l tank and official consumption is 2.9 l / 100 km.
- eyjafjallajokul 2y agoIt's 2.9L/100km for those who use metric. That is 34.5km/L or 81.1MPG. These numbers are incredible.
- zug_zug 2y agoLooks like google says prius gets anywhere from 45 to 78 MPG, which feels like too wide a window. Sounds promising but would love to see an exact apples-to-apples comparison before I get too excited.
- xela79 2y agosame I get with Mercedes CLA 250E over the last 40000km, drove 25640km electric only, good for average fuel consumption of 2.9L/100km and that 250E battery is good for 60km range in summer, 40km in winter
