While details for the new model are still to be released, BMW board member Frank-Peter Arndt confirmed the X4's coming during a speech earlier this year.
Now, according to website Autoweek, a concept version of the X4 is bound for Detroit - and if the Gran Coupe is anything to go by, the show-car should offer a solid preview of the final model.
The arrival of the sporting X4 will give BMW a contender in the growing 'SUV coupe' niche, where it will duke it out with Porsche's upcoming Macan, the Range Rover Evoque, and possibly a new 'Q4' from Audi.
The X6 has proven a strong seller for BMW, and it is likely this fact that has motivated a green light for the X4.
As with the X6, an X4 line-up could conceivably include an M-badged version, perhaps powered by the twin-turbo 3.0 litre six that drives the limited-edition 1 Series M, along with an M Performance diesel option.
