The Audi A8 lets its tech flag fly in the luxury executive class.
The standard bearer there has long been the Mercedes S-Class, and with an update for 2018, the S-Class now covers a spectrum that includes V-6s to twin-turbo AMGs, even plug-in hybrids, as well as coupes and convertibles.
The BMW 7-Series goes point for point on powertrains, on panache, and even on in-car fragrance dispensers.
Jaguar's XJ has less space, a more glitzy interior, and a lighter touch to the controls, and like the Cadillac CT6, it's a step below the Germans in prestige and in content, though Cadillac has Level 2 self-driving hardware.
The new Lexus LS has an expressive shape and a more advanced hybrid, but aims more for comfort than control.
