This scorching environment is perfect, especially considering that Cadillac is tackling heady competition in a hotly competitive luxury car field. Slotted beneath the existing , the smaller rear-wheel-drive ATS has a shorter wheelbase and will likely feature a range of turbocharged 4-cylinder and normally aspirated V-6 engines.
