New & Used BMW X4: In Depth
The BMW X4 is an as-yet un-released new crossover coupe, built to fit alongside the X3, just as X6 sits beside the X5. Even though it won't be launched in production form until sometime in 2014, likely as a 2015 model, a concept version of the model has given us a very good look at what we should expect.

As a coupe-like crossover, design is one of the primary reasons to consider the X4. It's of a size with the X3, being 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 Concept X4 are particularly dramatic, and while they're likely to be altered for production, we expect BMW to introduce new features here that may presage future change across the model line.
As for the X4's powertrain, the concept's spec sheet doesn't include any mechanical information. The X3 it shares most of its architecture with, however, gets its motivation from a choice of turbocharged engines: one a 2.0-liter in-line four-cylinder, and the other a 3.0-liter in-line six-cylinder engine. Rated at 240 and 300 horsepower respectively, these two engines offer a good compromise between power and efficiency in the X3, and should do the same for the X4. All-wheel drive is expected as standard, with an eight-speed automatic transmission shifting the gears.
Features and equipment are certain to follow the mold of BMW's existing X vehicles, including a wide array of exterior and interior color options, advanced electronics and entertainment gear, high-tech safety features, and more. BMW's iDrive infotainment system is sure to feature as well, with possible improvements to its interface and expansion of its capabilities.
The full details on the BMW X4 will be revealed soon--it's slated to make its official public debut in production form at the 2014 Detroit Auto Show.
