Some of the most elite people in the world in the course of modern history have driven and/or have ridden in a Cadillac sedan. Through the latter stage of the 20th century, Cadillac relied heavily on large sedans such as the Fleetwood and the Brougham. The Cimarron and Catera were unsuccessful efforts at a smaller Cadillac during the time. Since the start of the 21st century, the sedan market has garnered the most attention by Cadillac as the CTS has completely defined a new, modern impression for the historic American luxury car brand. Along with the CTS, The modern Cadillac sedan line-up is formed with the smaller ATS and the large XTS sedan. In 2016, Cadillac will sell an all-new flagship sedan called the CT6 available with available high-tech features such as Articulating Rear Seat package and a 34-speaker audio system.
