Im canadian so quoting Canadian numbers. My Rio is rated at 6.6l/100km city and 4.9 HWY. To translate that is 35 city and 48 hwy US numbers.
I regularly get about 8.0l/100km in the city and hwy im not sure as i haven't really driven it on the higway for more than a half hour, but the avg fuel economy will read around 6.2 which is 38mpg.
The van, well, i dont really drive it often, but after the wife has driven it the fuel economy usually reads mid teens L/100km or about 15mpg which is terrible. But i did manage to get just a hair over the sticker mileage which is 7.9 and i achieved 8.3 which is 28mpg.
Both cars are new. Rio has 1800km and caravan about 5000km
