Hot on the heels of the Chrysler-Fiat alliance announcement comes word that Chrysler is considering a crash program to fast track the Fiat 500 for sale in the U.S. If Chrysler gives the project the green light, it would be here in "well under 18 months," a source says. Set aside Fiat Group's clinic to determine whether it should bring in the 500 or the Alfa Romeo MiTo, the plan is to get the 500 into Chrysler-Dodge-Jeep dealers as soon as possible as a traffic-builder.
