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.
That is 34.5km/L or 81.1MPG.
These numbers are incredible.
Sounds promising but would love to see an exact apples-to-apples comparison before I get too excited.
and that 250E battery is good for 60km range in summer, 40km in winter
The misleading, wasteful way we measure gas mileage, explained
https://www.vox.com/future-perfect/350382/gas-mileage-fuel-e...
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.
