TCC’s Bottom Line
The 2018 BMW 7-Series is a plush ride with plenty of powertrain options and customizable features that places it among the full-size greats. The 2018 Cadillac CT6 has the style and performance to match its German rivals, but is the brand there yet? The 2018 Lexus LS 500 sedans don’t reach for the same performance limits as the LC coupes, but there’s ambition in every line.
