Luxury and Convenience
Step inside cars like the A6 or the CTS and you’ll immediately understand why these vehicles are so popular. The CTS is nearly unparalleled, offering more front-seat space than its competitors. The interior materials of the CTS can be fully customized, with a number of available wood and carbon fiber trims to create a meticulously personalized experience. The Audi features fewer interior trim materials from which to choose.
This year, Cadillac introduced an optional heated steering wheel that automatically turns on when sensors detect a cold temperature outside. Further adjustments include heated and ventilated driver and passenger seats; standard equipment on all trims above the base. Heated seats are standard on the Audi, but ventilated seats are only provided on the top Prestige trim.
Both the Cadillac and Audi present compelling infotainment packages. The customizable display nerve center provides access to Google Android Auto or Apple CarPlay on both vehicles, which also offer an option for wireless charging for your smartphone. Cadillac further offers Wi-Fi and LTE access to keep you and your passengers fully plugged in. Unparalleled sound is provided on the CTS by the standard Bose 11 or 13-speaker surround sound system. The base model Audi offers a 10-speaker system, with more robust sound systems included on the higher trims.
The Cadillac CTS is longer and narrower than the Audi C6, which gives it a sportier, more agile shape. Both vehicles’ trunks accommodate 14 cubic feet of storage space.
Even with the most well-built luxury cars, the warranty offers protection for those infrequent circumstances that require some attention. The Cadillac is backed by a 4 year/50,000 mile limited warranty with a 6 year/70,000 mile powertrain warranty and 3 years/36,000 miles of complimentary scheduled service. By contrast, while the Audi offers the same limited warranty, it provides only a 4 year/50,000 mile powertrain warranty and 1 year/10,000 miles of complimentary scheduled service.
Both the 2018 Cadillac CTS and Audi A6 are compelling mid-size sedans chock-a-block with luxury amenities. However, the Cadillac’s sportier size, engine options, and more generous warranty program help it to win the day. Come take a test drive today.
