The 2014 Cadillac CTS sedan is much longer than the four-door it replaces, and for good reason. The previous-gen CTS was a "tweener," a car balanced between compact and mid-size interior space. No more: the new CTS is a head-on competitor for the likes of the 5-Series, E-Class, A6, and XF.
According to the spec sheet, the 2014 CTS has grown 4.1 inches, to 195.5 inches overall, from nose to taillights. A 114.6-inch wheelbase has absorbed 1.1 inches of that growth. The roofline now sits at 57.2 inches, more than an inch lower than the prior car.
Cadillac's rearranged interior space, but the net effect isn't transformation. The CTS has decent head and knee room, so long as the optional sunroof is left on the option list. The 20-way seats are fantastic, formed with real care, especially for those who need upper-back support.
In back, the CTS doesn't displace the E-Class as the size queen. The low-mounted cushion aggravates an already low entry point. The doors are bigger, but older passengers in particular will have trouble getting in the back seat. There's less knee room than in an E-Class or a 5-Series. It feels more like a Jaguar XF, a conscious splitting of priorities between sleek looks and ample space.
The CTS' trunk wouldn't be called big unless it were on a coupe. At 13.7 cubic feet, it's barely adequate for a luxury car, but nowhere near the cubes offered up by a Passat or a Taurus.
The CTS sedans we've driven have impressed us, in terms of interior quality and fit and finish. Cadillac still offers a bit more glamor than Audi or BMW or Benz, and the contrast between glossy wood and brightly lit LED screens comes across more sharply than the subdued environment of an A6. We do like it better.
GM uses active sound cancellation to quiet the CTS' interior. The 4-cylinder benefits the most. It doesn't sound as happy or balanced as a BMW turbo-4, but the gruff overtones go mute. Twin-turbo V-6s get pumped-in noise to flood the cabin with good vibrations.
