AUBURN HILLS, MI - Chrysler Group LLC posted a $143 million operating profit in the first three months of the year, according to a statement by the automaker.

In Q1 2010, Chrysler net revenues increased to $9,687 million representing a 3-percent increase over the prior quarter, according to the company.

Growth was driven by continued price discipline on all products and some mix improvement due to the successful launch of the all-new Ram Heavy Duty pickup, as well as improved industrial efficiencies, a more stable supplier environment, and strict cost discipline on all discretionary spending.

Worldwide vehicle shipments in Q1 were 380,000, which included U.S. vehicle shipments of 268,000, both figures representing an increase of 3 percent versus Q4 2009.

In anticipation of a seasonally stronger selling season and increased confidence from Chrysler's dealer body and consumers, U.S. inventory was increased from 179,000 vehicles at the end of 2009 to 208,000 vehicles on March 31, 2010.
