Earlier Cadillacs with a sporty, firm suspension were designated as Touring Sedan models. The Seville Touring Sedan became a distinct, separate model in the line, and was referred to as the Seville STS, although this was repetitive. Later it simply became the STS, and the luxury variant became the SLS.
When the CTS arrived many felt that it might mean Catera Touring Sedan, but Cadillac suggested that it might mean C-class Touring Sedan. The C-class refers to a general size of car, such as the BMW 3-series or the Mercedes C-class. The CTS was actually larger than these models, but it gave insight on Cadillac’s naming conventions.
When SRX arrived, the X actually stood for crossover, as in sport recreational crossover. Yes, there is no X in crossover, but cross is occasionally abbreviated as X. For the XLR the X stood for eXperimental, as in experimental luxury roadster.
XTS in Cadillac XTS?
So what do the Cadillac XTS letters mean? I am sure Cadillac would say that they are the name of the car, and not an acronym. Since the XTS is a larger Cadillac, an imaginative response might be that they mean “Extended Touring Sedan”. In keeping with the XLR tradition they would mean “Experimental Touring Sedan”. Based on the sound the XTS name evokes, they might mean “Excellent Touring Sedan”. Since XTS is a showroom for new technologies and features, I feel that “Experimental Touring Sedan” fits it well.
