BMW, the world’s largest maker of luxury cars, expects to maintain double-digit sales growth this year in Brazil, where it may build an assembly plant, a senior executive said in an interview. Sales of BMW’s sedans, utility vehicles and hatchback models in Latin America’s largest economy will likely rise 25% to about 10,000 units, Jorg Henning Dornbusch, who heads the German carmaker’s Brazilian unit, told Reuters late on Tuesday. The number does not include sales of motorcycles. The introduction of new models is allowing BMW, whose sales are expanding five times faster than the national average, to boost its grip in Brazil’s burgeoning luxury car market. BMW controls about a third of that market, which sells about 35,000 units a year.
