Cadillac's gambit—to once again be the standard of the world—means taking on the world's finest executive luxury sedans with the new CT6.
Chief among the rivals is the S-Class, probably the finest car Mercedes has ever built, with a fantastic interior and variety in drivetrains, from AMG versions to plug-in hybrids.
The BMW 7 Series is a close challenger to the Benz, with worldly appeal and luxuriant custom-trim interiors.
Audi's A8 is gaining in appeal in this niche with twin-turbo V-8 power.
Jaguar's XJ did aluminum body when it wasn't as widespread; it has a daring look and thrilling performance, even if it's a little lean on back-seat head room.
Finally, the Lexus LS offers true luxury with a more conservative Japanese style.
