2013 Cadillac ATS......Future Cars

If it is in fact the V, this prototype is powered by either a small-block V-8 or a turbocharged six. We’re anticipating that the regular ATS will holster a V-6 from the GM range—probably the 304-hp 3.6 from the CTS’s shelf—and possibly a smaller, 2.8-liter V-6. A turbo four could power the base model. All-wheel drive likely will be an option, as will a choice of a six-speed manual or six-speed automatic transmission. Although the ATS will launch as a sedan, it is likely to eventually spawn a coupe and convertible as well.
