The Fiat Group may be constantly delaying Alfa Romeo’s return to the U.S. market but at least it’s keeping its word with the 500 range.

After the regular three-door hatchback and the rolling soft top 500C, Fiat is now introducing the most stimulating (from a driver’s perspective) version of the series, the sporty Abarth model, which will be making its debut at the 2011 Los Angeles Auto Show on November 18.

The Italian automaker said that the U.S. version of the 500 Abarth will sport a new 1.4-liter MultiAir turbocharged four, but did not disclose any information on performance figures.

The European specification 500 Abarth is powered by a 1.4-liter turbocharged engine producing 140HP and 206Nm in standard guise, and 160HP and 230Nm with the Essesse package.

Aside from the force-fed four, the Abarth model gains a stiffer suspension, a more powerful braking system, twin tail pipes, unique alloy wheels and a comprehensive aero package that includes a bespoke front bumper, side skirts, a roof wing and a rear diffuser.

To celebrate the launch of the new 500 Abarth, the Fiat Group also released photos and a new video detailing the history of the Abarth brand. You can check them out right after the break.
