No more engines. No call for exhaust pipes. Spark plugs? Gone with the electric-car wind. Or so, in essence, warns a recent widely circulated study that predicts the eventual demise of much of Hamamatsu’s gasoline engine economy. Reacting to that study and to a general sense of foreboding, carmakers, parts factories and local governments in this sprawling industrial town are joining forces to prepare for a future of electric vehicles. Suzuki Motor, based in Hamamatsu, helped found a regionwide alliance in October that will help parts makers develop new automotive technologies for electric cars and even for other industries.
