CT5

CT5 can refer to several things, most notably a Cadillac sedan. The Cadillac CT5 is a compact executive sedan produced by Cadillac, a division of General Motors. It was introduced for the 2020 model year, replacing the Cadillac ATS and CTS sedans. The CT5 is built on GM's Alpha 2 platform and is offered in rear-wheel drive or all-wheel drive configurations. It typically comes equipped with a turbocharged four-cylinder engine as standard, with an optional twin-turbocharged V6 engine available in performance variants like the CT5-V Blackwing. The interior features modern technology and luxury appointments characteristic of Cadillac's lineup.

Beyond the automotive context, "CT5" might also refer to specific scientific or technical designations, though these are less commonly known to the general public. For instance, in some fields, CT could stand for Computed Tomography, and the number 5 might denote a particular scan, protocol, or iteration of a device. However, without further context, the Cadillac CT5 sedan is the most prevalent interpretation of the term.
