With updated styling, the sedan looks sharper with the long hood and milder curves.

Fuel Economy
4.0/10

Frugal is not an adjective that describes the 2020 Cadillac CT6’s V6 underneath the hood. With an economy of 18 mpg in the city, 27 mpg on the highway, and a combined 21 mpg, the sedan is at best an average deal in the competition. The Porsche is quite impressive in its offering while the 4-cylinders powering the BMW 5 Series takes the lead in the rivalry albeit it’s really a no-go for its smaller displacement and size.

Interior
8.0/10

"The CT6 Platinum's cabin is swathed in leather, and chrome interior trim is thankfully sparse. Overall, the effect isn't quite as nice as what you get from Audi or Mercedes-Benz, but it's getting harder to pinpoint the flaws." -edmunds

Seating and Comfort

Stepping inside the CT6’s cabin would welcome you with so-so quality for a luxury sedan. Seating five passengers on leather seats, the Cadillac is simplicity abound with comfort and plush feeling but materials are not what you expect from a luxury class sedan. It undercuts the high-end opulent sedans with ease, making the CT6 a value for money in terms of quality and technology.

The cabin is spacious and allows for good legroom and headspace. Noise cancellation is great with quite interior even at highway speeds. The front seats can fall short on support but are still comfortable for long drives.

Infotainment System

The CT6’s cabin houses a 10.2” infotainment system with Cadillac user experience. The system is responsive to touch and is intuitive in usage. A big step up since its previous iteration, the controls of the system no longer feel clunky and it replaces the touchpad the manufacturer previously used. Some of the infotainment features include –

  • Cadillac user experience with 10.2" diagonal display
  • Bose Premium 8-speaker audio system
  • 4G LTE Wi-Fi Hotspot - includes data trial for 1 month or 3GB, whichever comes first
  • SiriusXM satellite radio for a limited trial period
  • Android Auto and Apple CarPlay

Cargo Volume

At the trunk of this luxurious sedan, the Cadillac can house 15.8 cubic feet of luggage space that is, in fact, an impressive feat by the American marque. While it does not lead the class as the most spacious cargo, that title goes to the BMW 7 series followed by the Porsche Panamera and the Lexus LS 500. The Cadillac is the least spacious but relatively has great space for a sedan.

Exterior
6.0/10

“Sleek styling and high-tech features help the CT6 shed the Cadillac clichés in an attempt to best its European rivals. Despite being smaller and cheaper than flagships from BMW and Mercedes, the CT6's halo status compels a comparison with those well-established rivals.” -carconnection

Design and Dimensions

Rolling on 18-inch wheels on all four sides, the long-hooded American luxury stands 58” high and measures a lengthy 205 inches to the back alongside a width of 74”. With curves forgone and replaced by sharp lines and edges, the Cadillac CT6 looks like the sedan is here on a serious business and not on a holiday. The front features the iconic Cadillac chrome-accented grille with the insignia pasted on it and flanked by mean-looking Bi-LED headlights.

The stretched limousine-like design sculpts all the way to the back with hard character lines running across the sides and a simple, yet elegant looking rear of the sedan meets much to the pleasure of the eyes. Although the craft of the CT6 is different this year, the sharp styling aesthetic has nothing special about it to make it stand out.

  • Bi-LED high-/low-beam projector headlamps and LED light pipe signature

Competition
7.0/10

Cadillac CT6 vs BMW 5 Series

Going up against the German luxury marque, the Cadillac CT6 consistently falls short of every parameter compared to the BMW 5 series. In terms of performance and handling, the Bavarian sedan outperforms it especially in regards to its driving dynamics. It also houses excellent safety features alongside more luxurious interior and technology. While the American Cadillac equips better storage capacity in the trunk, the BMW is still a better buy when adding the fact it costs lesser than the CT6.

Cadillac CT6 vs Mercedes Benz S-Class

The American luxurious sedan, Cadillac CT6, heavily undercuts the Mercedes S-Class purely in terms of value for money. While the German from Stuttgart overhauls the CT6 in terms of luxury, opulence and driving dynamics, the Cadillac brings up its arsenal when its price is into consideration. It all depends on how much you’re willing to shell out, for both the sedans are actually a great car in itself.

Final Verdict

Even in its updated form, the Cadillac CT6 does turn heads but not due to its styling, - no no, it does so simply due to its simplicity and features offered in its price range. Granted, there are other rivals with better sophistication and that is missing in the CT6. Having said that, the American luxury marque is swiftly climbing the ladder to rival the best of the brands out there in the market.
