Although the sedan body style continues to dwell near the bottom of the heap in terms of U.S. sales volume, General Motors still has a few four-doors left in its roster – three, to be exact, specifically the Chevy Malibu, the Cadillac CT4, and the Cadillac CT5. With two-thirds of GM’s U.S. sedan lineup carrying a Cadillac badge, it’s interesting to note that Cadillac sedans appear to be morphing in terms of design, with the exterior layout adopting a four-door coupe profile.
This design change started with the Cadillac CT5, which debuted a rapidly sloping roofline, lending it a sportier appearance than a traditional three-box sedan. A similar design motif was also applied to the Chinese-exclusive second-generation Cadillac CT6.
By comparison, the Cadillac ATS sedan, every generation of the Cadillac CTS, and the first-generation Cadillac CT6 all offered a more traditional three-box layout. Currently, the only Cadillac sedan to follow the traditional three-box design is the CT4, which, incidentally, was never even supposed to have happened, as GM Authority was the first to report.
Looking back, the four-door coupe body style was originally pioneered by the German automakers, starting with the Mercedes-Benz CLS Class. Since then, the body style has made its way to a variety of German models, including:
- Mercedes-Benz CLA-Class
- BMW 2 Series Gran Coupe
- BMW 4 Series Gran Coupe
- BMW 6 Series Gran Coupe (now discontinued)
- BMW 8 Series Gran Coupe
- Audi A5 Sportback
- Audi A7 Sportback
- Volkswagen CC
- Volkswagen Arteon
All of these models have a rapidly sloping roofline, and all have frameless windows as well.
Cadillac, meanwhile, has been somewhat sluggish in its adoption of the four-door coupe body style. It could also be argued that the CT5 and second-generation CT6 aren’t “true” four-door coupes, as neither is equipped with frameless windows.
Either way, the bottom line is this – two out of three Cadillac sedans currently on the market have a coupe-like profile. And while the Germans may offer four-door coupes as a complement to traditional three-box sedans, the coupe-like profile seems to be where Cadillac sedans are now – and possibly where they’re headed in the future, as well.
