Ever-tighter fuel economy and emissions regs, not to mention changing consumer tastes, have automakers doing more with less.
Fiat is taking it to a whole ‘nother level by putting a tiny two-cylinder engine in the adorable 500.
Fiat says the TwinAir 875cc will be the world’s most fuel-efficient gasoline automobile engine — getting 57.4 mpg — when it appears in the 500 this fall.
It meets Euro 5 emission regs and will allow Fiat to retain its position as the European automaker with the lowest overall fleet CO2 emissions.
