TURIN, Italy—The body shop at Fiat’s flagship Mirafiori plant here has started to assemble the company’s first all-electric vehicle with Comau welding robots.

Most people associate control rooms with nuclear power plants, oil refineries or NASA rocket launches.

Several Fiat factories in Europe, including Pomigliano, Italy, and Tychy, Poland, were benchmarked by engineers from Chrysler’s Belvidere Assembly Plant before producing the new Dodge Dart.

Chrysler Group LLC is betting big on its new Dodge Dart compact sedan, which hits dealer showrooms in June.

The Dodge Dart compact sedan differs significantly from the two other vehicles that are built at Chrysler’s Belvidere, IL, assembly plant—the Jeep Compass and Jeep Patriot sport utility vehicle.
