The information was first reported by Edmunds, which is also claiming the ATS Coupe will feature the same powertrain lineup as the current ATS sedan. That means a base 2.5-liter four-cylinder engine, mid-level 2.0-liter turbo four and range-topping 3.6-liter V-6. ATS Coupe buyers should also have the choice of a six-speed manual or six-speed automatic transmission.
Cadillac is planning to launch a high-performance ATS-V sedan in the near future, and it’s likely the ATS Coupe will also have its own high-performance variant.
As previously reported, the ATS Coupe won't follow the CTS Coupe's dramatic departure from the CTS sedan's shape, instead favoring a shared set of lines, but with longer door openings and a revised roof line. A second generation of the CTS Coupe is unlikely to be launched, meaning Cadillac’s future two-door lineup will consist of only the ATS Coupe and ELR.
Other rumored variants of the ATS include the aforementioned ATS-V version, as well as a wagon and a convertible.
