DETROIT — Nissan Motor Co. will begin producing the hybrid version of its midsize Altima sedan in the United States in 2006, Nissan President Carlos Ghosn said Jan. 10, according to an article in the Japan Times. During a news conference at the 2005 North American International Auto Show in Detroit, Ghosn said the automaker will decide annual output of Altima hybrid cars based on demand, but the maximum will be 50,000 units per year. Nissan is expected to assemble the hybrid at its factory in Smyrna, Tenn., where it currently manufactures the standard model. Nissan signed an accord with Toyota in September 2002 on procurement of a hybrid car engine system.
