General Motors Corp. and Suzuki Motor Corp. will delay the decision on where to build a jointly developed car until at least September, which is six months later than initially planned. The four-wheel-drive YGM-1, based on a Suzuki platform, is to be GM's first passenger car to be designed and built in Asia. In March, GM said the companies would choose a production location for the new model by the end of the first quarter, hinting it would be built at a Suzuki plant.
