According to AutoWeek, Pontiac is scaling back its Vibe line, discontinuing the GT and all-wheel-drive versions after the 2006 model year due to poor sales and changes in U.S. emissions standards. The Vibe, also sold as the Toyota Matrix, is the product of NUMMI, a joint-venture between GM and Toyota based in Fremont, California. The Vibe, reported to be sticking around through 2007, would be the last GM product produced at NUMMI, which also handles the Corolla, Tacoma pickup, Matrix (and its Japan-only counterpart, the Voltz), barring a new model set for the plant. Could the world's number-one and number-two be planning to go their separate ways after years of carmaker-on-carmaker love? If there's a divorce, maybe GM will get the market share. California's a community-property state, no?
