The XTS is Cadillac's flagship sedan. It's sized and priced to compete in the heart of the luxury market against import sedans like the Audi A6, BMW 5 Series, Lexus GS and Mercedes-Benz E-Class. The XTS seats five and is available with front- or all-wheel drive.
Not long ago, Hyundai expanded its lineup with the rear-wheel-drive Genesis — a car intended to emulate midsize luxury cars like the BMW 5 Series and Mercedes-Benz E-Class for less money. Hyundai has a sort of super Genesis in the Equus, an even larger sedan that aims to take on the BMW 7 Series and Lexus LS at a price point one rung lower.
The 2015 Lincoln MKS luxury sedan looks the part of a luxury car, with clean lines, an impressive grille, and plenty of high-tech gadgets filling the interior. While Lincoln may have Audi and BMW aspirations for its biggest sedan, the reality is that it's not quite up to the sophistication levels of those cars.
The 2015 Kia K900 feels like a Kirkland brand luxury sedan from Costco — tasty and much less expensive than a name-brand model, but falling short in sophistication, refinement and cachet. Outside of South Korea, the idea of a super-plush, full-size, rear-wheel-drive Kia luxury sedan seems like the answer to a question nobody asked.
