Among ultraluxury sedans, the BMW 7 Series has always played second fiddle to the Mercedes-Benz S-Class. But the current 7 aced our tests, with an impressively steady ride, silky-smooth powertrain, good handling, and a sumptuous cabin. The base 740i is powered by a 3.0-liter turbo six-cylinder. Our typically equipped 750i, with the polished and punchy 445-hp, 4.4-liter turbo V8 and all-wheel drive, rang in at $110,645. Although the controls have a steep learning curve, they prove logical once mastered. The luxurious interior is super-quiet, with impeccable attention to detail and supremely comfortable seats. Interior quality is superb, with the wood, leather, suede, and aluminum trim delivering a modern ambience without looking glitzy.
