1. 2018 Mercedes-Benz S-Class

The 2018 Mercedes-Benz S-Class is loaded with style on the exterior and interior. The carmaker was heavy-handed with the use of luxurious materials throughout and comfortable seating for everyone. This thing could replace the den in your home, it’s so nice.
With your choice of a turbocharged 362 HP 3.0L V6 or turbocharged 463hp 4.0L V8, a nine-speed automatic transmission and available all-wheel drive, the 2018 Mercedes-Benz S-Class has more than enough power.
New this year is the Energizing Comfort System that ties together a number of features in order to truly pamper everyone inside along with an updated COMAND® Navigation System, and a wireless cell phone charging pad.
2. 2018 Cadillac CT6

While the ATS may have lost its way (see it below on this year’s list of worst models), the 2018 Cadillac CT6 sits at the other end of the scale. On the outside, the CT6 offers bold styling and angular design. On the inside, the cabin offers enough space to seem palatial.
The CT6 offers responsive handling and the standard turbocharged 2.0L four-cylinder offers 265 hp and plenty of zip. For those who need more power, the 404 HP 3.0L twin-turbo V6 will definitely push you back into your seats.
Standard features include a 4G WiFi hotspot, OnStar, the Cadillac CUE interface with a 10.2-inch screen and full Apple CarPlay and Android Auto compatibility.
3. 2018 Volvo V90

Where Volvo was once considered to be the mainstay of solid and safe automobiles, the 2018 Volvo V90 takes the revered status of the Volvo station wagon to an all new level.
Far from the boxy lines of old, the V90 offers sinuous lines that flow smoothly, giving it a sleek look reminiscent of the entire lineup of today’s Volvo. Even the base model comes loaded with a wealth of the latest features in a cabin filled with top-quality materials and a design worthy of the finest luxury cars on the market.
4. 2018 Genesis G90

The Genesis G90 made its world debut last year as the flagship for this new company. While it remains essentially the same from its introduction last year, it also means it continues to have little in the way of faults.
Inside you’ll find a luxurious and spacious interior loaded with enough high-tech wizardry to satisfy even the most tech-hungry buyer. Under the hood sits a stout-hearted turbocharged 3.3L V6 or a 5.0L V8 depending on the model you choose. Each is connected to an eight-speed automatic transmission and rear-wheel drive. All-wheel drive is offered on all models.
Among the more popular standard features are automatic LED headlights, adaptive cruise control, keyless entry and ignition, heated folding side mirrors, and tri-zone automatic climate control.
