Fiat unveils new 900cc TwinAir two-cylinder engine

Fiats of old used to feature noisy two-cylinders with a fetish for overheating, yet the Italians are at it again, this week releasing details of their new TwinAir two-cylinder 900cc engines. You can see how it works in our video below. The new engines, the first in a series of two-cylinders by the Italians, are designed to trump all other downsizing efforts. Headline figures from the 83bhp twin are 23% more power than the regular 1.2 four-pot and the same as a 1.4 16v - yet with 30% less consumption.
