Fiat Twin Air

As promised earlier this year, Fiat has officially adorned their beloved 500 with a brand new engine option: the 2-cylinder TwinAir.

The 85 HP, turbocharged 0.9 liter engine reportedly has the performance characteristics of a much larger 1.4 liter, 16-valve engine, but it consumes about 30% less fuel—resulting in a fuel economy of 57 mpg as rated on the combined Euro cycle. If it were sold in the U.S. and rated on the EPA cycle, that number would likely drop to around 50 mpg.

Unfortunately for now, there are no plans to sell the 85 HP TwinAir engine as an option on any of the Fiat 500’s that are rumored to be reaching U.S. shores by the end of this year.
