Not that long ago, the BMW most likely to double as a personal limo was the &-series sedan, but the 2022 X7 SUV is stepping into the role of rolling palace for the rich. With more real estate to exhibit its expensiveness and six seats spread among three rows, the biggest Bimmer is well-suited for affluent families. While the cargo area and way-back seats aren't as roomy as those in rivals such as the Jeep Grand Wagoneer  and Mercedes-Benz GLS-Class, the X7 drives better and boasts a selection of more desirable powertrains. Backed by a terrific automatic transmission and standard all-wheel drive, the engine hierarchy includes a 335-hp turbocharged inline-six and a 523-hp twin-turbo V-8. The 612-hp Alpina XB7 affords ridiculous levels of performance for a machine this massive. Regardless of what's under its high hood, the 2022 BMW X7 has gobs of upscale content and high-tech features as well as an interior that's as quiet as a library but both comfier and ritzier.
