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.

Ferrari 599XX Evoluzione Ferrari has had a play with the track-only 599xx, added more power and improved aerodynamics and created the ultimate 599 – the Ferrari 599XX Evoluzione. There are road Ferraris and there are track Ferraris. And the Ferrari 599XX carries on the tradition of hard-core track-only cars for wealthy clients (like the FXX) where ultimate performance is achieved by ignoring homologation rules for any race.

1984 Ford Mustang SVO: American metal, European performance

If the 1978 Ford Mustang King Cobra II isn't quite your thing, why not give the 1984 Ford Mustang SVO a try? In the Jan. 3, 1983, issue of Autoweek, we previewed a different take on the pony car -- one that promised "visual subtlety with unsubtle performance." Built on the Fox platform, the Mustang SVO (for "Special Vehicle Operations") wasn't supposed to be a flashy package for the wannabe racer -- it was designed from the ground up to be a balanced road car, "a state-of-the-art performance vehicle for the absolutely no-compromises performance buyer." And when we say "ground up," we mean it.
