New United Motor Manufacturing, Inc.(NUMMI) is the pioneering joint venture of General Motors Corporation and Toyota Motor Corporation. Established in Fremont, California, in 1984, NUMMI helped change the automobile industry by introducing the Toyota Production System and a teamwork-based working environment to the United States.

Today, NUMMI has grown to become a company of 5,500 team members who produce three award-winning vehicles: Toyota Corolla, Toyota Tacoma and Pontiac Vibe. In 2002 NUMMI began producing a right-hand drive Toyota, Voltz, which is exported to Japan.

Throughout its history, NUMMI has worked hard to create a unique corporate culture that borrows from Toyota, General Motors and the nearby Silicon Valley environment. NUMMI's collaborative partnership with the United Auto Workers has been the topic of numerous labor relations studies. The company's core values are based on five cornerstones: teamwork, equity,involvement, mutual trust and respect, and safety.
