This weekend I took a Rio for the day to experience this vehicle in the commuting situation that it will be most often used for. First of course was the drive home on Friday night. Everyone who considers the Rio wants to know what they can expect for gas mileage. The energuide ratings for the Rio says that it gets 6.8 l/100km (41.5mpg) city and 4.9 l/100km(57.6mpg) hwy. I drove the vehicle through the city on routes with speed limits varying from 50km/hr to 80 km/hr. I was able to keep moving forward and did not spend an unusual amount of time sitting at red lights or train crossings and with the Active Eco engaged I had an overall mileage of 6.0L/100km which translates to 47 mpg. Not bad for a city drive!
