The Cadillac CTS is a luxury car that was manufactured and marketed by General Motors from 2003 until 2019 across three generations. Historically, it was priced similarly to cars on the compact luxury spectrum; but it has always been sized closely to its mid-size rivals. The third generation competes directly with the mid-size luxury cars. Initially available only as a 4-door sedan on the GM Sigma platform, GM had offered the second generation CTS in three body styles: 4-door sedan, 2-door coupe, and 5-door sport wagon also using the Sigma platform — and the third generation was offered only as a sedan, using a stretched version of the GM Alpha platform. Wayne Cherry and Kip Wasenko designed the exterior of the first generation CTS, marking the production debut of a design language (marketed as 'Art and Science') first seen on the Evoq concept car. Bob Boniface and Robin Krieg designed the exterior of the third generation CTS. The CTS ended production in 2019 and was replaced by the CT5, which shared its platform with the third and final generation of the CTS in addition to the smaller CT4. (Source: Wikipedia.org, CC BY-SA)
