A considerable four door sedan with new edge styling, the vehicle advantages of exactly the same Magnetic Ride Control suspension system found in the XLR, meaning it possesses a mixture of handling and ride previously unknown in Cadillacs of the size.

Little luxuries abound within the capacious body, and the driver gains a configurable electronic instrument cluster.

This is a car aimed squarely in a younger, urban buyer; Wail Street is going to be kerb-to-kerb with one of these cars soon.
