The ATS is handsome, packs cutting-edge technology and offers handling as sharp or sharper than its BMW and Audi compact luxury sport sedan rivals. The 2015 Cadillac ATS sedan comes in with a very subtle styling refresh that includes a new grille texture, a wider lower front air intake and restyled Cadillac badges. The latter grow in width and shed their wreaths for a more modern look. More notable updates are under the skin, where Wi-Fi capability and wireless charging debut and the turbocharged four-cylinder engine sees a boost in its torque output.
