Unlike other car fuel economy surveys, TrueDelta's Gas Mileage Survey includes questions about how and where a car was driven. So you can get an idea of the smart fortwo's real-world gas mileage (MPG in US and UK, L/100km elsewhere) based on how and where you drive a car.
- view all responses; guests view a maximum of five MPG (or L/100km) gas mileage responses per smart fortwo powertrain
- filter gas mileage results based on driving style and driving conditions

About TrueDelta's smart fortwo Gas Mileage Survey
Tire Decision Guide

Government estimates often aren't indicative of actual, real-world gas mileage for the smart fortwo.
Here, unlike anywhere else, you can learn what actual fuel economy and gas mileage (MPG) to expect from the smart fortwo based on how you drive and the roads you typically drive on. TrueDelta's Gas Mileage Survey (formerly the Fuel Economy Survey) is the only one to ask smart fortwo owners about driving style, terrain, A/C use, driving speed, and other factors that can affect the smart fortwo's fuel economy and gas mileage in the real world.
And, members can now filter real-world smart fortwo gas mileage results by the most important factors.
