2014 Cadillac CTS

Based on a stretched version of GM's excellent Alpha platform architecture that was introduced on the 2013 Cadillac ATS, the new CTS Sedan is some five inches longer and an inch lower than the 2013 model while adding 1.6 inches of wheelbase. Cadillac hastens to point out that those changes finally move it from "tweener" status to full-on mid-size scale. However, the most critical spec change is that the 2014 CTS also is some 250 pounds lighter than its predecessor depending on trim and will roll into showrooms later this fall weighing significantly less than any of its luxo-sedan rivals. More extensive use of aluminum - including the first all-alloy doors on any Cadillac and lightweight front structural and suspension elements  - not only helped trim total mass but also allowed CTS engineers to optimally position the remaining poundage in places that endow all versions of the car with a near 50/50 weight balance.
