The Cadillac CTS has always been a bit of a anomaly in the luxury segment, spanning the space between the entry-level BMW 3 Series/Mercedes-Benz C-Class/Audi A4 and mid-size 5 Series/E-Class/A6. But with the introduction of the 2013 Cadillac ATS, the CTS has room to grow, and based on these first set of spy shots, it's doing just that.
Based off a stretched version of the Alpha platform that's underpinning its smaller sibling, the 2014 CTS' wheelbase is likely to grow a few inches, affording rear seat passengers up to 40 inches of leg room. While the front overhangs are still short and will continue on with Cadillac's Art and Science design motif with angular headlamps that stretch up the front fenders, the rear will likely extend a bit further back, maximizing trunk room in the process.
It's expected that the base engine will continue to be a V6, but churning out something in the neighborhood of 350 horsepower, possibly through the use of forced induction. The current six-speed automatic will likely be swapped in favor of a new eight-speed auto 'box to keep up with the rest of the luxury set.
If we had to place bets, we'd put our money on the 2014 CTS debuting at the Detroit Auto Show next year, with sales beginning late in 2013.
