The ATS coupe, which is on a later lifecycle, will continue into the 2019 model year.
“Production of the ATS Sedan is ending due to extensive plant upgrades, expansion and re-tooling to prepare for the next generation of Cadillac sedans,” Donny Nordlicht, a Cadillac product communications specialist, told TTAC.
“Cadillac’s future sedan portfolio will consist of three sedans, positioned in different segments and clearly differentiated by size and price.”
Under the plan laid out by former Cadillac chief Johan de Nysschen, the ATS, CTS and XTS would disappear after 2019, and be replaced by two sedans: the CT4 to fight the BMW 3-Series, and the CT5 to take on the BMW 5-Series.
