2019 Cadillac XTS vs. 2019 Audi A8

The Cadillac XTS is a mid-lineup model from Cadillac available as a sedan, and the 2019 Audi A8 is a similar vehicle of higher price with a few feature differences. If your hunt for a great luxury sedan has come down to these two finalists, take a look at our comparison to see which one best suits your style and needs.


One of the largest differences between these two luxury sedans is their pricing. The 2019 Cadillac XTS has a base MSRP of $47,890, and the 2019 Audi A8 has a base MSRP of $84,795. Keep in mind that the A8 is Audi’s most expensive sedan from its 2019 lineup, a flagship model with only one fully-equipped trim level. The XTS, by contrast, is a mid-level sedan for Cadillac’s lineup which starts much lower than the A8 in price but offers higher trim levels for increasingly greater packages and convenience.


The Cadillac XTS has a 3.6-liter V-6 engine equipped for front-wheel drive with a six-speed automatic transmission in the base model. The 2019 XTS also offers a more powerful engine if drivers want to spend a little more. As for the A8, only one engine is available: a 3.0-liter V-6 equipped for all-wheel drive with an eight-speed automatic transmission. At a glance, the A8 might seem to offer a bit more horsepower, with 335 versus 304 in the XTS base model. However, if drivers opt for the stronger Cadillac V-6, the XTS jumps to 410 horsepower, leaving Audi’s sedan far behind.

Luxury & Convenience

The XTS and A8 are very similar on the inside, and brands like Cadillac and Audi are known for spacious and well-designed cabins with fancy materials. Features from the A8 are either included standard with the base-model XTS or available on higher trim levels, so you can get the same features without paying as much as you would for a new A8.

Fuel Economy

Brands like Cadillac combine luxurious aspects of car ownership while still lending an ear to practical issues such as fuel economy. In this case, the XTS and A8 both have the same combined miles per gallon of 22. However, the XTS stands out because its engines use regular gasoline, while Audi’s model requires more expensive premium fuel.


Luxury cars like the Cadillac XTS usually have a basic warranty of four years or 50,000 miles, and that applies to the Audi A8 as well. For the drivetrains, owners get a six-year or 70,000-mile warranty with the XTS, while the A8 only offers four-year/50,000-mile terms. Roadside assistance also comes included with both sedans, but the terms are quite different: six years or 70,000 miles for the Cadillac XTS and four years or unlimited miles for the Audi A8.

The Audi A8 is only available in a single trim level, drastically reducing the potential for drivers to shop smart and pick a model with the features they need. When factoring the high price that brands like Audi often charge with the A8’s similarity to the XTS, the latter will most likely be the easy choice.
