7. 2021 Lexus LS

The 2021 Lexus LS sits at the bottom of our full-size luxury car rankings because of a small backseat and a finicky infotainment system (a common complaint with Lexus vehicles as of late). On the positive side of things, the LS has an upscale cabin with premium finishing materials and great reliability ratings.
6. 2021 Genesis G90

The 2021 Genesis G90 also packs a large number of standard features into a competitively priced vehicle. The G90 features sporty engine options, an intuitive instrument layout, and a comfortable interior design. One of the few knocks against it is below-average fuel economy ratings.
5. 2021 BMW 7-Series

The BMW 7-Series has a superb drivetrain that allows it to float down the road surefootedly and responsively. Being a BMW, it comes with a long list of standard and optional tech features, and it features a plush cabin with refined materials.
4. 2021 Audi A8

Once you close the door on your Audi A8, the sounds of the outside world are left behind. The quiet and comfortable ride is further accented by a handsome interior layout and a spacious interior cabin.
3. 2021 Tesla Model S

For those wary of electric vehicles, the Tesla Model S will convince any skeptic. It's peppy. It has agile handling. It has the long range necessary for worry-free road trips. It's roomy and luxurious so you don't feel cheated out of the upscale price. The minor drawbacks that kept it from the top spot are no smartphone integration (in 2021!) and an infotainment interface that can be somewhat distracting (basically a 17-in. iPad).
2. 2021 Porsche Panamera

The 2021 Porsche Panamera features powerful engines and responsive steering that will have you zipping in and out of traffic on your way to the office or while running your errands about town. With its comfortable seats and spacious interior, it will be fun for drivers and passengers alike.
1. 2021 Mercedes-Benz S-Class

Frankly, the Mercedes-Benz is extravagant. The interior design is unlike anything else in the market and to say the features list is comprehensive would be an understatement. Add to all that a powerful engine and fine-tuned driving, and you've got one of the best full-size luxury cars available.
