The Mercedes-Benz E-Class and BMW 5-Series are mainstays among luxury mid-size sedans; they’re the high-water marks for the class.
The E-Class offers a wide range of powertrains, but no plug-in hybrid (yet).
The 5-Series has a hybrid, but lacks some of the polish of the Benz.
Both are worth comparing to the Volvo, although the S90 may have a better base version.
The Audi A6 is new this year and its only available with a V-6; if efficiency is part of your shopping criteria, the Volvo is a better bet.
The Lexus GS and Cadillac CT6 are outliers in the class; the Lexus is relatively old but should be inexpensive, the Caddy has a limited shelf-life but offers SuperCruise in some areas.
Choose wisely.
