The BMW F25 is the next generation model of the BMW Sports Activity Series X3, scheduled for 2010. The 2011 X3 was unveiled on July 14, 2010. The new car is slightly larger than its' E83 predecessor and will be assembled in Greer, South Carolina along with the X5, X6, and upcoming X1. Power for the North American version of the X3 will come from BMWs' new N53 3.0L Direct Injection I6 engine for the xDrive28i from the new F10 528i and BMWs' new N55 3.0L Twin Turbo Direct Injection I6 engine for the xDrive35i as seen in its' larger facelifted X5 sibling. Both engines will be mated to either a 6-speed manual or 8-speed automatic transmission. The U.S. version will only get the 3.0 inline-6 and automatic transmission combination and no four-cylinder diesel engine version will be sold.
