What Our Members Are Saying about the Real smart fortwo MPG

smart fortwo Fuel Economy: Pros
Year Body/Powertrain Comment
2013 2dr Coupe 70-hp 1.0L I3 5-sp automated manual RWD good mpg car for the price and simplicity of a lightweight car with only a gas engine. Even if you only get the EPA combined estimate of 36 it is good mpg and competes well in its class. But many smart drivers get much higher. My first 10k miles averaged 45 mpg, based on miles per gallon measured at each fill up, mix of city and freeway. Recently I had 48 mpg and 51 mpg tanks on my usual route. Check Fuelly.com for a realistic picture of mpg to expect. Low 40s mpg is most common.
2009 2dr Coupe 70-hp 1.0L I3 5-sp automated manual RWD fundamentally adequate, very predictable, no surprises larger fuel tank would still be nice
