The C stands for "C class".
The TS stands for Touring Sedan.
This is very close to right. The CTS is actually just a continuation of the Cadillac Catera, although the CTS is not made in Germany. The "C" stands for Catera, as in Catera Touring Sedan. You may also notice that the Deville and Seville have been replaced by the Deville touring sedan (DTS) and the Seville touring sedan (STS).
"CTS" stands for "C-Series Touring Sedan." CTS-V is the sports model and a bit more expensive. The abbreviation has nothing to do with the Catera.
