The BMW X4 is the latest coupe-like crossover to join the German automaker's lineup. Just as the X5 begat the X6, the X3 is the source code for the X4. It works downward, taking the X3's running gear, then wrapping it a faster rear roofline, with a more sporty stance and a lower roofline.

Why choose the X4 out of all of BMW's hatchbacks, wagons, coupes, and SUVs? BMW argues it's for the design. It doesn't have much different a footprint than the X3--it's 1.3 inches wider, 1.5 inches lower, and exactly the same length--but the proportions are completely different, as are many of the details.
The X4's low, arched roof earns it its claim to coupe-likeness, while strong, dynamic character lines along the side add further hints of athleticism not normally seen on crossovers. At the nose of the X4, you'll find a very familiar version of BMW's familial styling, with SUV cues, including a set of wide, deep air inlets, an apparent skidplate (or skidplate-mimicking design), and, of course, the signature kidney grille. The headlights of the X4—twin round units—are quite dramatic, and complemented by LED fog lamps. Toward the rear, the X4 has the ‘signature swage line’ alongside—split in two here, for a more dynamic look—while in back the X4 is probably at its most conventional, with a treatment that looks quite carlike, only lifted-upward.
The 2015 X4 will be offered in xDrive28i and xDrive35i models, with the xDrive28i offering up the now-familiar 240-horsepower, 2.0-liter turbocharged four-cylinder engine that’s used widely in the current BMW lineup. X4 xDrive35i models will be powered by the 300-hp, 3.0-liter turbocharged in-line six. And in both cases, there’s an eight-speed automatic transmission and all-wheel drive.
Since underpinnings are largely carried over from the X3, we expect much of the X3’s driving experience to extend here—meaning that the X3 rides tall like a crossover, but launches with every bit of the authority of a sport sedan, and without the squat and nosedive that are pretty typical in crossovers. The variable sport steering system is standard here, as are steering-wheel paddle shifters. And while the X4 really doesn’t look that trail-focused, expect that mild off-road ability won’t be outside its ability set.
There’s seating for four adults in the X4, with the back seats providing molded-in side bolsters good for two adults—but technically providing space for three across. A power tailgate is on the standard-features list and can be optioned with a Smart Opener that lets you use your foot to cue it to lift. The X4’s cargo space ranges from 17.7 cubic feet with the back seats up in place to 49.4 with the seatbacks forward.
Features and equipment follow the mold of BMW's existing X vehicles, including a wide array of exterior and interior color options and upholstery variants, advanced electronics and entertainment gear, high-tech safety features, and more. The X4 includes BMW’s new iDrive controller; it incorporates a touchpad, allowing you to trace out individual characters in destination entry or selecting names from your phonebook. Rear Park Distance Control is a standard feature as well, and an available M Aerodynamics Package will bring a collection of sporty BMW M finishing touches to the look.
