If this smart new production car seems a little familiar that’s because a similar looking and identically named ‘concept’ was shown back at the 2008 Detroit show. Virtually unchanged on the outside and set to feature the excellent cabin of its CTS saloon sibling on the inside, it will take on upmarket coupes like BMW’s 3-series and Infiniti’s G37 this spring in the US. Official UK sales could follow by 2011.www.cadillac.com
