The new 2009 Nissan 370Z touts improved power, efficiency, handling and updated sheet metal for under $30,000. That makes the 370Z a bit of a performance bargain, and when you consider improved fit and finish, lighter weight and impressive new technology upgrades, Z fans should be plenty happy. While it's nice to see high resolution pics of the new car, we like to see how it looks out on the road, as well. Follow the jump to check out Nissan's rolling stock footage, which contains plenty of shots of the 370Z out on twisting paths. There are also several diagrams that spell out how upgrades like Nissan's variable valve and SynchroRev Match tech works.
