Cadillac has announced the discontinuation of its compact CT4 and mid-size CT5 sedans, effective June 2026 and by the end of 2026, respectively. This decision marks a significant shift for the brand, which has long been associated with luxury sedans. The move reflects broader trends in the automotive market, where sedan sales have been steadily declining.
In 2024, Cadillac sold only 6,208 CT4s in the U.S., a figure that highlights the challenges faced by this model. The CT5 performed slightly better, with 14,861 units sold in the same year. Despite being one of the best luxury cars available for under $30,000, the CT4 received mixed reviews, particularly regarding its interior space. Conversely, the CT5 has generally been better received, as indicated by its sales figures.
Future of Cadillac Sedans
While the discontinuation of these models may disappoint sedan enthusiasts, there is a silver lining. According to John Roth, Vice President of Global Cadillac, the CT5’s legacy will continue in the form of a next-generation model that will feature an internal combustion engine. Specific details regarding the new powertrain and platform remain undisclosed, leaving fans eager for more information.
There is speculation that the upcoming CT5 may retain some of its powerful engine options, including the twin-turbo V6 or the impressive 668-horsepower 6.2-litre supercharged V8 found in the 2025 CT5-V Blackwing. It is anticipated that multiple engine options, including a hybrid variant, could be available.
Cadillac is also looking towards the future with plans for two electric sedans currently in development. As reported by GM Authority, one of these electric vehicles will be comparable in size to the CT5, while the other will be similar to the now-discontinued CT6. This could imply that the new internal combustion engine CT5 might share a platform with these electric models, or they could be based on entirely different architectures.
Market Trends and Platform Evolution
The CT4 and CT5 are built on GM’s Alpha 2 platform, an updated version of the original Alpha platform first introduced in 2013. Although an 11-year platform cycle is not unusual, it does feel somewhat outdated in comparison to competitors in the rapidly evolving automotive landscape. As Cadillac navigates this transition, the brand’s focus on electric vehicles aligns with industry trends toward sustainability and innovation.
The discontinuation of the CT4 and CT5 sedans is emblematic of a larger shift in consumer preferences, as more drivers gravitate towards SUVs and electric vehicles. As Cadillac refines its lineup, the future of its sedans remains uncertain but promising, with potential for revitalization through innovative engineering and design. The automotive industry will be watching closely to see how Cadillac adapts to these changing dynamics.
