Introduced for the 2013 model year, the first-generation Cadillac ATS won’t get a replacement. The luxury automaker just confirmed that the four-door sedan will be discontinued after the 2018 model year. The ATS was developed as a competitor for the BMW 3 Series and Mercedes-Benz C-Class, but it wasn’t exactly successful against its German rivals in the U.S. Following sales of more than 20,000 units per year between 2013 and 2016, ATS deliveries dropped to only 13,000 examples in 2017. Cadillac will continue to offer the ATS Coupe model into the 2019 model year; a company spokesman told Motor Authority.
