The following information is speculative and has not been confirmed or otherwise announced. If you notice any inaccuracies or have suggestions about the information provided, please let us know here.



Here’s what we expect from the Cadillac CT4:

  • Based on the shorter variant of the Cadillac Alpha 2 platform
  • Feature Cadillac’s new design language similar to the Cadillac Escala concept and Cadillac XT6
  • Introduce an improved interior over the first-generation ATS, with increased levels of refinement, luxury, and convenience
  • Include the Cadillac Super Cruise autonomous driving technology
  • Introduce a plug-in hybrid/PHEV variant like the CT6 Plug-In Hybrid or a pure battery electric variant
  • Follow the Cadillac Y Trim Level strategy, with the following trim level structure:
    • Luxury
      • Premium Luxury
      • Sport
      • V-Sport


We expect the Cadillac CT4 pricing to start at $30,000 range, since the CT4 will have to slot below the CT5 – which will start in the $35,000 – $45,000 range, which ex-Cadillac president Johan de Nysschen stated in 2017.

Release date

Cadillac has not yet announced when the Cadillac CT4 will come to market, but we expect it to launch in the 2019 calendar year as a 2020 model year vehicle after the CT5.


The CT4 name is the result of Cadillac’s new naming scheme, wherein the brand labels cars like sedans, coupes, and wagons with the CT moniker, followed by a number designating its “sequence” in the lineup. Similarly, Cadillac crossovers and SUVS will be named XT followed by a number identifying its sequence 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 Cadillac CT4 will ride on the successor to the original Alpha platform known as the Alpha 2 platform, shared with the following vehicles:

  • Cadillac CT5
  • Next Chevrolet Camaro (seventh generation Camaro)

As such, the CT4 will have a longitudinal powertrain configuration with rear-wheel-drive or all-wheel-drive.

The CT4 carries the A2SL vehicle code internally at Cadillac and its parent, General Motors.


We expect the Cadillac CT4 to feature the following engine choices:

  • Turbo 2.0L I-4 LSY engine with automatic engine stop/start functionality making about 280 horsepower in Luxury, Premium Luxury and Sport models (gasoline)
  • Twin-Turbo 3.0L V-6 LGW with automatic engine stop/start functionality making 400 horsepower for CT4 V-Sport (gasoline)
  • Cadillac Twin-Turbo 4.2L V-8 making in the vicinity of 500 horsepower for CT4-V (gasoline)
  • New turbo-diesel engine for select markets (diesel)
  • Electric plug-in hybrid/PHEV (gasoline/electric)

We expect that the Cadillac CT4 will be offered with the new 10-speed automatic transmission. The plug-in hybrid model will have its own powertrain.

Body Styles

We expect the Cadillac CT5 to be available as a midsize sedan. A coupe and convertible variants are probable. A coupe variant is possible, but a wagon is out of the question.


We expect that the Cadillac CT4 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


Cadillac CT4 specifications are not available at this time. We will update this section when Cadillac releases information about the vehicle.
