The recently restyled 2020 BMW M760i is one of those cars, but the M in the name hints that this sedan should also be pretty rewarding for the lucky person who gets hired to pilot the thing.
The 2020 Audi S8 provides nearly the same power from its mild-hybrid V8 powertrain, and I prefer its infotainment system, but it's not on sale in the US just yet.
The Mercedes-AMG S65 is probably the closest Merc comes to the M760i, while it's still on sale, as the Mercedes-Maybach S-Class' two trims are both significantly more expensive than the Bimmer, although the S650 is the only other way to get a V12 nowadays.
It can be a surprisingly sharp performer, despite its size and heft, but it's most at home with everything in Comfort mode, rolling down the street like there's a permanent air gap between car and concrete.
