I've tried to compile the history of the Versa from introduction in June 2006 to the 2010 model just released. If you see any mis-information, please let me know.

Model History:The Nissan Versa was introduced in the U.S. in June 2006 as an all-new model to the North American market. The Versa / Tiida B-platform is sold in North America, Japan, Europe, and other Overseas Markets, with the largest market in North America (USA). The Versa development emphasized comfort and usability in a compact package, with styling cues from a Murano inspired front and 350Z inspired rear. The engine in the Versa is the MR18 and has 'Best in Class' standard horsepower/torque rating at 122HP / 127 lb-ft torque. Combined with a spacious 17.8 cubic foot cabin and excedptional rear leg room, the Versa utilizes every inch of its dimensions to the fullest potential. The 2007 Nissan Versa wins Consumers Digest’s “Best Buy Award”.
