In a significant shift for its vehicle lineup, Cadillac announced that it will discontinue the CT4 and CT5 sedans by the end of 2026. This decision comes as the company navigates a declining market for sedans, which has seen sales steadily decrease in recent years. The compact CT4 will cease production in June 2026, while the mid-size CT5 will conclude its run later that same year.
Cadillac’s decision to phase out these models is not entirely surprising. In 2024, the company sold only 6,208 units of the CT4 in the United States, a figure that underscores the challenges facing traditional sedans. The larger CT5 performed slightly better, with sales reaching 14,861 units in the same year. Despite being one of the best-value luxury cars available for under $30,000, the CT4 received mixed reviews, particularly regarding its interior space. In contrast, the CT5 garnered a more positive reception, reflected in its stronger sales figures.
Future of Cadillac’s Sedan Lineup
While the discontinuation of the CT4 and CT5 marks the end of an era for Cadillac’s sedan offerings, there is a silver lining for fans of the brand. John Roth, Vice President of Global Cadillac, confirmed that the legacy of the CT5 will continue with a next-generation model featuring an internal combustion engine. Although specific details about the new model’s powertrain and platform remain unclear, speculation suggests it may retain the high-performance characteristics that have defined the CT5, including the potential for multiple engine options and a hybrid variant.
Additionally, Cadillac is developing two electric sedans. According to GM Authority, one of these models will be comparable in size to the CT5, while the other will match the discontinued CT6. This development raises the possibility that the new internal combustion engine CT5 could share its platform with the upcoming electric sedans, or alternatively, be based on an entirely new architecture.
Currently, both the CT4 and CT5 utilize GM’s Alpha 2 platform, an updated version of a system first introduced in 2013. While an eleven-year platform cycle is not unusual, it feels somewhat outdated in the context of the rapidly evolving automotive landscape. The future developments at Cadillac will be closely watched, as the brand strives to adapt to changing consumer preferences and market dynamics.
As Cadillac moves forward, it faces the challenge of maintaining its luxury appeal while embracing the shift towards electric vehicles. The discontinuation of the CT4 and CT5 could signify a broader transition for the brand, as it seeks to redefine its identity in a competitive market that increasingly prioritizes sustainability and innovation.
