Honda Motor Co. is making $355 million worth of upgrades at plants in Ohio where it opened its first U.S. wind tunnel in 2010, seeking productivity and fuel-economy gains for models designed and built in North America.
The Ohio projects for the first Japanese car manufacturer to make cars in the U.S. include $166 million in improvements to its factory in East Liberty and a $64 million stamping press at its Marysville plant, said Ron Lietzke, a spokesman for the company's assembly unit.
Honda declined to provide any figures relating to the cost of the wind tunnel upgrade or other additions to its engineering center in Raymond.
