Remember the most recent spy photos of the Cadillac CT5 that we shared on Tuesday? Turns out that it’s not the CT5 at all, but is instead our first look at the upcoming sub-CT5 model, the Cadillac CT4.
The camouflage tape made the CT5 and CT4 prototypes look extremely similar, likely giving GM’s camo designers a good laugh before our colleagues at Cadillac Society figure out (via a painstaking pixel-by-pixel analysis running well into the wee hours of the night) that we are looking at two entirely different models.
A word about naming: we currently do not know whether the sub-CT5 Cadillac sedan will be called CT4 or CT3. For the sake of sanity, let’s refer to it as the CT4 for the time being.
Though the CT5 and CT4 prototypes have similar shapes made even more similar by the heavy camo, the door cut-lines and greenhouse lines of the CT4 are very different from those on the CT5. First, take a look at the rear door and the C-pillar treatment of the CT4 and then do the same for the CT5.
The smaller CT4 features a shorter rear door with no glass or door elements on the C-pillar, much like the current Cadillac ATS. The same is very much different on the CT5. Despite its heavily-camouflaged C-pillar, it’s rather obvious that the larger model will feature a vanity rear window on the C-pillar just behind the rear door, much like the Cadillac CT6.
The differences between the two prototypes don’t end there. Out back, the two models have different decklid treatments that lead to different locations for the license plate cutout, plus different treatments for the bumper cover and exhaust outlets.
The uninterrupted horizontal lights are still part of the camo package that make the car look like a Dodge Charger tester, giving those GM camo artists a reason to hi-five as they read this… camo tape in hand. But make not mistake about it: production models with ship with lights similar to those on the 2019 Cadillac CT6, itself inspired by the Escala concept.
The changes out front are not as noticeable as they are on the sides or the rear. But look closely, and you’ll see different hood lines, differently-sized mirrors, and slightly different stance and general front-end proportions. And while the different mirrors might be the result of market-specific regulation standards (the current CTS ships with one set of mirrors for the Americas and another for Europe), the variations in hood cutlines are undeniable.
The GM Authority Take
At the end of the day, we are looking at two different vehicles: one is the smaller CT4 and the other is the larger CT5. Both will be based on the second iteration of the highly-acclaimed GM Alpha platform known as Alpha 2. In first-generation guise, the architecture underpinned the ATS and CTS lines.
Both the CT4 and CT5 will be built at the GM Lansing Grand River plant in Michigan for American markets. The Jinqiao Cadillac plant in China will likely build both vehicles for the Chinese market. Other markets such as South Korea and the Middle East will receive shipments from these two plants.
