BMW has never signed onto the traditional SUV concept. The company doesn't even call its vehicles SUVs -- it refers to the X5, X3, and X1 as Sports Activity Vehicles. It blurred the lines further with the X6, dubbed a Sports Activity Coupe.

Considering the pattern BMW followed with its SAVs, starting with the largest vehicle and following with progressively smaller ones, it makes sense that the company has introduced a new concept SAC that's smaller than the X6, but follows a similar philosophy. This one is called the X4 Sports Activity Coupe Concept.

BMW's Sports Activity Coupes are made to combine the best aspects of a coupe -- carlike driving dynamics, unique styling with features like a long hood and short overhangs -- with the best aspects of an SAV. The result: a vehicle that blends the rugged styling and some of the cargo volume of an SAV with the looks and handling of a coupe. That's the same idea here, in a smaller vehicle than the X6.

Not much information has been released regarding the X4, but we do know the Concept is shown with 21-inch light alloy wheels, is on a 110.6-inch wheelbase, and measures 183.0 inches long, 75.4 inches wide, and 63.9 inches tall. The wheelbase is the same length as that of the current X3. We expect the production X4 will generally stick to the same dimensions as the Concept, as the X6 has the same length wheelbase as the X5 (115.5 inches). This also suggests a logical place in the line for an even smaller SAC based on the X1. Following the idea of the X5 versus X6, the X4 could be powered by the same engines as in the X3, namely the 200-hp, 2.0-liter twin-scroll turbo I-4 and the 300-hp, 3.0-liter twin-scroll turbo I-6.

While we don't know how close the styling of this concept vehicle is to the production model, it looks like it could easily become reality with little or no changes. BMW has confirmed that the X4 Sports Activity Coupe is not just a concept; it will go into production. Production is scheduled for 2014 in Spartanburg, South Carolina, where the X6, X5, X3, and X1 are also manufactured.
