The car introduces "a new generation of aesthetic language for Cadillac," according to Andrew Smith, Cadillac's executive director for global design.
The CT5 is built on a version of General Motors' well-known Alpha platform, versions of which have also been used for ATS and CTS, as well as the Chevrolet Camaro.
Your engine choices: a 2.0-liter turbocharged four-cylinder or a 3.0-liter twin-turbo V6, both paired to a 10-speed automatic transmission.
As on other recent Cadillac models, the CT5 will be sold in a so-called "Y" trim strategy that splits between Luxury and Sport models.
Cadillac will build the CT5 at its Lansing Grand River plant in Michigan, having invested $221 million to upgrade the facility for the new car.
A tablet-style touchscreen with an updated version of the company's CUE infotainment software sticks up from the dashboard. It can also be controlled by a console-mounted rotary controller, as seen in the XT4 and XT6.
The Cadillac CT5 will go on sale toward the end of 2019.
