Cadillac is rapidly expanding its CTS range - first of all we scooped the coupe version
, and now our spies have snapped the estate on test in the United States.
The company is expected to show the wagon at the 2009 Detroit auto show, and it's clearly aimed at the estate versions of the 5-series/E-class/A6. Check out our shot with the boot open and you'll see that the CTS estate is a lifestyle model, with a sloping tailgate for sleeker looks rather than an Eiger-like vertical boot, Volvo-style.
We're not quite sure what the engineers at the US facility were testing, but it was scooped on a turntable.
