@bscar2 - The ATS will be RWD (so it shares nothing with the Malibu or Cobalt):
“If you love driving, the new Alpha architecture that underpins the Cadillac ATS could well be the single most important investment in hardware GM makes this decade. The lightweight Alpha architecture ensures rear drive cars have a future at GM despite tougher fuel economy targets worldwide. And not just in terms of variations on a baby Cadillac theme.”
