The Car Connection's Take
TCC Rating
7.8
7.8
TCC’s Bottom Line
The 2019 Audi A8 plots out the course for next-level self-driving cars, and utilizes other technology to advance its luxury and connectivity. The 2019 BMW 7-Series is a flagship luxury sedan in the way they used to be: leather everywhere, big power, excellent options. The 2019 Cadillac CT6 is smarter and more powerful, but will that put it on more driver's radars?
