The Jeep, Dodge and FIAT brands each posted year-over-year sales gains in May compared with the same month a year ago.

"For the third consecutive month, our Jeep brand recorded its best sales month ever helping Chrysler Group to achieve its 50th-consecutive month of year-over-year sales gains. The Dodge Dart compact car had its best sales month ever, while our Ram pickup truck recorded another double-digit sales increase."
