One of the advantages of getting to an Auto Show early - you get to see rehearsals and get a jump on the competition.
The XTS is bigger than CTS, and will be pitched against Mercedes-Benz E Class, BMW 5-Series, Audi A6, et al. Cadillac claims it has more passenger space than any of them.
The 3.6 litre V6 engine drives all four wheels through a six-speed automatic. Full-time four-wheel drive, Magnetic Ride Control and Brembo brakes are standard.
XTS also introduces CUE - Cadillac User Expeience - a system that Cadillac says brings in-car connectivity to a new level. This will migrate into other Cadillacs in the coming months.
