The Car Connection's Take
TCC Rating
7.2

7.8
TCC’s Bottom Line
The 2020 Audi A8 is a futuristic flagship that raises the bar with its high-tech features. The 2020 BMW 7-Series has a much bigger grille, but behind it is a posh, powerful, thirsty luxury sedan that’s loaded with tech. The 2020 Mercedes-Benz S-Class is the benchmark for large luxury sedans.
