The 2020 CT5 measures 193.8 inches (4,924 mm) in length, 74.1 inches (1,883 mm) in width and 57.2 inches (1,452 mm) in height, with a wheelbase of 116.0 inches (2,947 mm).
Despite its Fastback styling, it’s almost as long as a BMW 5-Series, which measures 194.3 inches (4,936 mm) bumper to bumper. Meanwhile, the CT5’s wheelbase is actually longer than that of an Audi A6 (115.1 inches / 2,924 mm). Also, here’s how it compares to a 2019 CTS: 114.6 inches (2,911 mm) wheelbase, 72.2 inches (1,834 mm) width, 195.5 inches (4,966 mm) length – the CT5 is bigger in every way except overall length, but again, that’s because of its styling.
Before you voice your objections in the comments, we asked Cadillac for clarification, and they insisted on describing it as a “compact” premium sedan that will be competitively priced within that segment as well.
