Here is the first official sketch preview of the upcoming BMW X4. The sketch features the rear view of the X4 concept and reveals a sleek SAV with many of the design aspects already mentioned by BMW insiders.
At a marketing presentation with the F25 X3 project leader, it was revealed that the BMW X4 Concept will be presented sometime next year, with production in 2013-2014. The X3 lineup may also be expanded soon with an X3 M, xDrive35is, and Active Hybrid versions.
What does the future of the BMW X portfolio hold? According to insider Scott26, BMW is keen on a potential X4 (think smaller X6) which shares technology with the X3, an X3 35iS sharing engine from z4 35iS and 335iS, and an X3M with motor from upcoming 1M Coupe.
