Sporty BMW X4 based on the X3 in the works

According to Autocar, BMW is working on a sporty version of the X3, which will be called the X4. Apparently, the Bavarian car maker wants to repeat the X6 recipe with the X4 (you take a popular SUV, create a sporty version of it and then let money come to you). Scheduled to go on sale in 2014, the X4 will be a four-seater (just like the X6) and BMW even consider an M version of the model.It
