BMW's premiere luxury SUV gets a new look for 2019, along with plenty of high-tech upgrades. Borrowing styling cues from the all-new 5 Series, the fourth-generation X5 gets a bolder and sleeker redesign. Then there's the myriad of the in-car features like a revised iDrive system with gesture control, 3D navigation. Under the hood is a 3.0-liter turbo-diesel inline-six that is connected to an eight-speed automatic transmission and xDrive all-wheel drive.
