The Car Connection's Take
TCC Rating
7.6
6.4
7.8
TCC’s Bottom Line
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. In its final year, the 2020 Cadillac CT6 is a tempting look at what could have been from the luxury brand. The 2020 Mercedes-Benz S-Class is the benchmark for large luxury sedans.
