宝马计划将X7 SUV家族进一步扩大，可能会增加一款M版车型。据宝马博客透露，宝马高管正在讨论是否推出X7 M。如果获批，该车将搭载4.4升V8涡轮引擎，功率将提升至不低于620马力。与引擎搭配的是双离合自动变速器并标配全轮驱动。如果上述规格听起来很熟悉，是因为该车整个动力传动系统都取自下一代M5，该车预计将于明年初发布。由于动力增加，该车还将配备更大刹车盘，经过运动调校悬挂和肌肉感车身组件。目前还不清楚该车内部可搭乘七名乘客还是四名乘客；不过标准版X7内部搭乘七名乘客，不过宝马计划将这款超豪华衍生车型的内部只搭乘四名乘客。宝马计划于2019年推出X7，而X7 M即便获批投产最早也要等到2020年才会发布。

BMW planning X7-based super SUV?
BMW's upcoming range-topping X7 SUV could spawn the company's biggest M-tuned model.

Enthusiast website BMW Blog has learned BMW executives are debating whether to build a X7 M. If approved, the model will land with a turbocharged 4.4-liter V8 engine tuned to generate no less than 620 horsepower. A dual-clutch automatic transmission and all-wheel drive will come standard. If those specifications sound familiar, it's likely because the entire drivetrain will also be found in the next-generation M5 that we expect to see early next year.

The extra power will be complemented by bigger brakes on all four corners, a sport-tuned suspension, and a muscular-looking body kit. Whether the X7 M will offer space for seven or just four passengers is up in the air; the standard model will come standard with seven seats, but BMW is planning an ultra-luxurious variant with room for four.

The BMW X7 is scheduled to arrive in 2019, a timeline that suggests the X7 M won't arrive until 2020 at the earliest if it's approved for production.
