First Generation

The first-gen CT4 is a traditional sedan with a regular trunklid, yet it has a fastback-like profile. Notably, the four-door sedan styling is the only available body configuration at this time. The sleek design rides on the Alpha 2 platform, which is an updated version of the first-generation Alpha platform that underpinned the Cadillac ATS and CTS.

“We developed CT4 to appeal to youthful buyers in the luxury market who may be new to the Cadillac brand,” said Andrew Smith, executive director of global Cadillac design. “The vehicle was intended to draw attention, using a combination of great proportions, taut surfacing and Cadillac family details that hint at the athletic driving experience this vehicle offers.”

The CT4 also incorporates the latest Cadillac technologies, including Super Cruise, the world’s first true hands-free driver assistance feature for more than 200,000 miles of compatible highways in the U.S. and Canada. Other technological highlights for the first-generation CT4 include:

  • Active Thermal Management
    • Uses targeted engine heating and cooling to improve performance in hot and cold ambient temperatures
  • Integrated exhaust manifold
    • Recovers heat for faster engine and transmission warm-up
    • Quicker turbo response
  • Electric water pump
    • Increases efficiency and enables continual cabin heating, even when the engine is off during stop/start events
  • Tandem solenoid starter
    • Enables a faster response from a stop/start event and enables a smoother take-off

As for the CT4 moniker, the name is the result of Cadillac’s new naming scheme, wherein the brand names all sedans and coupes as CT followed by a number designating its order in the lineup. Similarly, Cadillac crossovers and SUVS are named XT followed by a number identifying its order in the vehicle hierarchy.

General Motors filed a trademark application for the CT4 name with the Untied States Patent and Trademark Office on November 7th, 2014. The 2020 CT4 made its debut in the third quarter of 2019, and went on sale early in the 2020 calendar year in the United States with a starting price of $33,990 for the Luxury trim with rear-wheel drive.


The Cadillac CT4 was designed and engineered to compete with other compact sport-luxury sedans in the C segment, including:

  • BMW 1/2 Series
  • Mercedes-Benz A-Class
  • Audi A3 range
  • Acura ILX
  • Volvo S40/V40
