GENEVA (AP) — Fiat and Chrysler CEO Sergio Marchionne says he may shift the date of the Dodge Dart's production launch off of April 1 to "to avoid being jinxed" by an April Fool's Day launch.

The Dodge Dart is the first Chrysler model to use Fiat architecture under the nearly three-year-old alliance.

Marchionne on Tuesday called the Dodge Dart "a huge step forward in terms of moving the brand into the American heartland."

Fiat, which controls a 58.8 percent share of Chrysler, sells the city car 500 in the United States, hitting sales of 2 million last year.

It plans to bring over the 500L — a larger version of the 500 that was launched at the Geneva Motor Show on Tuesday — in 2013.
