SAO PAULO, Brazil — General Motors is planning for long-term profitability in South America built on the back of draconian cost cutting during Brazil's recession and the same low-cost vehicles it is developing for Chinese consumers, which are due to hit dealerships in 2019. "We have been refreshing the vehicle family (in South America), building up market share and getting the cost point right, all in preparation for one vehicle family," GM President Dan Ammann told Reuters in a recent interview.
