A source from within the German luxury car brand revealed to UK website Autocar that although it is yet to be given the nod for production, the X4 is indeed being looked at seriously.
“We haven’t made any firm decision ... however, the X6’s success shows there is a continued demand for sporty off-roaders,” the source said.
Since its launch in 2008 when it was labelled “the automotive world’s answer to the question nobody asked”, ‘nobody’ has purchased 80,000 examples of the X6 around the world, doubling initial targets.
In Australia, BMW sold 112 X6s in the first quarter of 2010, and last year outsold the Porsche Cayenne (573 vs 562).
It has been speculated that an X4 could use the platform of the upcoming X3, which is due for release late 2010/early 2011.
BMW initially gave hints of an X4-style vehicle in 2001 when it unveiled the X Coupe concept at Detroit.
