Small engine, big pitch.

Italian automaker Fiat is using a new video to wax poetic about its TwinAir family of engines designed to boost performance in its smaller cars while cutting fuel use and emissions.

The three-plus-minute video, put together by Frame Communication, outlines the TwinAir engines, which range from 65 to 105 horsepower and include a turbocharged version as well as an option that runs on compressed natural gas (CNG).

Fiat says the TwinAir engines boost fuel economy and cut emissions by 30 percent compared to similarly-sized mills while providing as much as 120 horsepower per liter of displacement. The engines are adaptable to hybrid use as well.

Fiat and its Chrysler affiliate have been eschewing electric-drive powertrains as a method of boosting fleetwide fuel economy in favor of smaller, more technologically-advanced internal combustion engines. For example, in August Fiat unveiled the turbocharged 2013 version of its 500 compact. That model features a detuned version of its 1.4-liter MultiAir turbocharged inline-four, which boosts horsepower and torque by 34 horsepower and 52 pound-feet from the 2012's non-Abarth version, respectively.
