#2018CadillacCT6

Think back to your youth — no matter your age — and picture a proper luxury car from that era. Unless you’re a precocious teen stumbling upon this site, I’m certain you imagined some sort of plush sedan. Whether a powerful yet reserved Mercedes-Benz, a Broughamtastic Cadillac Sedan DeVille, or a stately Lincoln Town Car, the traditional three-box sedan has defined the ultimate in automotive opulence since the Second World War.

No longer, it seems. Today’s titans of industry are wholly given over to unfamiliar affections, finding happiness in another kind of conveyance: the big SUV. Whether Escalade, Navigator, or G-Class, rising above the poors means being seen above the poors. If design govern in a thing so large, whither tradition?

Since the default for extravagant luxury seems to be a full-size SUV, the traditional big floaty sedan’s days seem to be numbered. Does the 2018 Cadillac CT6 rage, rage against the dying of the breed? Or does it go gentle — with Super Cruise — into the good night?

Setbacks notwithstanding, we’ve been eagerly anticipating Cadillac’s entry into the world of semi-autonomous driving with its Super Cruise system, developed to help reinforce the automaker’s position as top-tier luxury brand. After all, vehicular opulence is now deeply embedded with technological achievement and few things shout “I’ve arrived” like a car that can chauffeur you around.

However, Cadillac is changing its implementation strategy, making Super Cruise standard on the highest trimmed CT6 — instead of leaving it as a pricy optional extra. It’s also launching an advertising campaign to whet the public’s appetite, with the first of its “Let Go” TV spots appearing on MTV’s Video Music Awards over the weekend.
