Chrysler Group LLC announced Tuesday that its U.S. sales jumped 22 percent in April, which is its best April sale since 2008, as truck and car sales each notched double-digit increases.

The significant increase in April car sales was driven by strong demand for the new 2011 Chrysler 200 and the new 2011 Dodge Avenger mid-size sedans, the company said.

And sales of the new 2012 Fiat 500, up 76 percent from March this year, also helped to boost its car sales in April.

"Both our retail car and truck sales were up significantly in April as we continued to build upon our sales growth momentum on the heels of a solid first quarter," said Fred Diaz, President and CEO of Ram Truck Brand and Lead Executive for U.S. Sales.

"Our mid-size cars had their best month since March 2008, and every Jeep and Ram Truck model that we sell experienced a year-over-year sales gain in April," Diaz said.

"Our truck and SUV sales remained strong in April even in the face of rising gas prices at the pump. Our new product line up is resonating quite well with consumers," He added.

Chrysler has reported growth over prior year level for 13 month in a row; its sale jumped 17 percent in 2010, compared with 36 percent decline in the year of 2009. Chrysler sales rose 23 percent so far this year.
