Acura plans to unveil a new version of its TSX sports sedan next month at the New York International Auto Show.

The 2009 TSX, which will go on sale in the spring, is the second generation of the luxury brand's entry-level sedan. The company said the new version will have improved performance, styling, technology and safety features.

"The TSX is a significant step in the advancement of our sedan lineup and the continued enhancement of the Acura brand," Dick Colliver, Acura's executive vice president for sales, said in a statement.

The company did not announce the price or details of the new features. The current model starts at $28,190, it says.

Acura, the luxury brand of Honda Motor Co., is hoping the new TSX can help revive sagging sales. It sold 33,037 TSX models in the U.S. last year, down 13.1 percent from 2006. Acura sales dropped 10.5 percent from the previous year.

The new car, which looks sleeker and meaner than its predecessor, will be introduced during media preview days March 19 and 20. The show opens to the public for a sneak preview March 21 and runs until March 30.
