Think, a Norwegian maker of electric cars that once was a unit of Ford Motor Co., plans to build an assembly plant and technical center in the U.S.—possibly in Michigan. Starting capacity of the plant would be 16,000 units/year, expanding to as many as 60,000. Production of the company's only model, the TH!NK city, would begin in 2010. The tech center would employ about 70 engineers and electric-drive specialists, the company says. The 2288-lb (1038-kg) two-seater with a recyclable plastic body can travel 112 mi (180 km) on a single charge. Think spokesman Brandon Prebo said the company plans to increase range and top speed, which currently is 62 mph (100 km/h). It also plans to switch from the currently used sodium-nickel battery to lithium-ion types from two U.S. companies: A123Systems and EnerDel.
