The Cadillac CTS might be the most appealing evolution of Cadillac's chiseled, Art & Science styling theme. It's more adventurous, perhaps less cookie-cutter inspired, than its organically shaped import-brand competition. Yet the CTS looks both classy and handsome.

The CTS line is often compared to compact luxury sedans like the or , and that may be a function of similar pricing. By exterior dimensions, the CTS is actually as large or slightly larger than mid-size models like the or . The Cadillac's impression of a more compact size probably speaks well of its overall design.

The CTS sedan and the new Sport Wagon are identical from the front bumper to about the middle roof pillar. The egg-crate grille design for V6 models is common across Cadillac's lineup. Vertically stacked headlight clusters make heavy use of LED (light-emitting diode) technology, which delivers lots of light and allows lots of style with little electrical load. The air vents or extractors near the trailing edge of the front fenders have been re-designed with a more open appearance for 2011.

The Cadillac CTS sport wagon might be more handsome than the sedan, if only because its proportions are almost perfectly balanced. The integrated spoiler at the rear edge of the wagon's roof serves as both an aerodynamic device and the center high-mount brake light. The standard power liftgate can be operated with either the key fob or a switch at the rear of the car. A simple dial inside the gate allows its opening range to be adjusted, from just-above-roof height for short folks or tight garages to nearly vertical upward extension.

The high-performance Cadillac CTS-V models get unique, functional styling features, starting with larger wire-mesh grille work above and below the front bumper. This doubles the amount of air flowing into the engine bay, increasing cooling capacity for the engine, transmission and front brakes. An aluminum power-dome hood provides a slight bulge to accommodate the supercharged V8 underneath. Huge Brembo brakes, wedged into thin-spoke, 19-inch forged wheels and extra-wide tires, comprise one of the most engaging visual elements on the car.

The big wheels aren't reserved for the CTS-V models, however. For 2011, Cadillac offers 19-inch wheels with all-season tires on all CTS sedans and wagons, including those with all-wheel-drive. Wheel options range from 17 to 19 inches, and from painted to highly polished.
