It has been more than a year since we saw BMW reveal the X7 Concept at the Frankfurt Motor Show. Serving as a prelude to a future production vehicle, the X7 Concept will be BMW's first-ever seven-seater and is touted to be their most luxurious model to date.

Now, BMW has officially released the first teaser image of the X7 in production form. Just like the original concept, the X7 features an imposing dual kidney grill. Each side comes with seven vertical slats that further highlight the X7's girth and immense size. Equally large are the LED headlights and the faux corner air intakes on the front bumper.

Other details regarding the X7 have yet to be revealed. However, thanks to patent images that were leaked last August, we already know how the X7 will look like when it's fully revealed. A sleek pair of taillights flank the rear corners of the X7 while dual exhaust pipes exit through the rear bumper which adds a sporty finish. As a whole, the X7 remains faithful to its concept origins.

Images of the X7's interior were not yet revealed. But based on previous spy photos, it appears that the X7's dashboard will have a similar design to that of the X3 and X5. More than likely, the X7 will have a large infotainment display, a digital instrument panel and multi-info display, and a wide array of smart technologies.

A host of turbocharged engines are expected to be available in the all-new X7. BMW's 4.4-liter twin-turbo V8 and 3.0-liter turbo-diesel inline-six are expected to be the prime engine choices for the X7 upon its release. However, a plug-in hybrid variant could also be available in the pipeline.

Like the X3, X4, X5 and X6, the X7 will be built at BMW's Spartanburg factory in South Carolina, USA. The BMW X7 is expected to make its world debut soon.
