Chrysler Group LLC, a subsidiary of Italian Fiat SpA (Milan: F), reported on Friday that May U.S. auto sales up 30 percent, the best showing for the month in five years and the 26th consecutive month of year-over-year sales gains for the revivified company.

Detroit-based Chrysler Group sold 150,041 vehicles in May and projects a seasonally adjusted annual selling rate (SAAR) of 14.2 million. Chrysler brand sales were up 81 percent for the best May sales in four years with the Chrysler 200 sedan gaining 87 percent and the Chrysler 300 posting triple-digit gains.
