This vehicle is the X3's twin brother, but with a gym membership. The two are identical from a mechanical standpoint, but the X4 has a more slender shape and unique style. 2019 sees the release of the second generation of this model, which was first introduced in 2014. Like the X3, the BMW X4 comes in xDrive30i and M40i variants. The latter, which is equipped with a 355-horsepower, 3.0-litre six cylinder, can really move.
