This all-new Jetta will be based on the same platform as the Golf that debuted in Europe last fall. The revamped Jetta will get a longer wheelbase and a wider track, but the styling isn't likely to differ much from the current version. The engine lineup won't change much either, but the 3.2-liter V6 is a possible addition. It's expected to go on sale in the U.S. next spring.
