The GM Alpha platform currently underpins General Motors' compact to mid-size, front-engine, rear-wheel and four-wheel drive vehicles. Platform basics include MacPherson struts on the front, 5 link independent rear, use of high strength steel and aluminum, and an overall focus on reducing weight. The GM Alpha platform made its debut in the 2013 Cadillac ATS, which entered production in July 2012.
