[custom_adv] Nothing says class like arriving somewhere in a huge luxury sedan. Crossovers and SUVs (there are a lot!) may be having their moment in the spotlight, with even exotic and luxury brands getting into the game, but full-size luxury sedans were there before, and they’ll be around long after the SUV fad fades. [custom_adv] The idea of ranking these best-of-the-best vehicles may seem absurd, but there has to be a preeminent choice—even among these contenders for preeminence. If your idea of a Cadillac is a plush-riding luxobarge, then the XTS is the Cadillac for you—although you really should hurry, since the XTS is being discontinued soon. [custom_adv] With a 304-hp V-6, a six-speed automatic, and front- or all-wheel drive, it’s perfect for the senior citizen in us all—or for real senior citizens. The V-Sport has a 410-hp twin-turbocharged V-6 and all-wheel drive, but even this sportier trim is not much fun to drive. [custom_adv] In Italian, “Quattroporte” means “four doors,” but you don’t need to speak the language to appreciate this Maserati’s dramatic flair. Two twin-turbo engines are offered—a 424-hp 3.0-liter V-6 and a 523-hp 3.8-liter V-8. An eight-speed automatic and rear-wheel drive are standard; all-wheel drive is offered with the V-6. [custom_adv] Inside the sumptuous, leather-lined cabin is an 8.4-inch infotainment system with Apple CarPlay and Android Auto; adaptive cruise control and automated emergency braking are optional. [custom_adv] If you're not looking too closely, Lincoln’s Continental appears to be an impressive sedan. It is handsome, large, and offers some fun color combinations and oodles of chrome trim inside. It’s a modern take on the classic American luxury barge, after all. [custom_adv] Closer inspection, however, reveals the Continental’s plebeian roots: Switchgear borrowed from far lesser Ford-branded products, unrefined ride and handling motions, and inefficient V-6 engines.
