You know you’re doing well with your marketing when demand for a crossover of a car that hasn’t been produced yet is gaining steam.

That’s the scenario BMW finds itself in when the BMW X1, which will be released in introduced in Europe at the Frankfurt Motor Show in September, is now scheduled to have a US version to be released in 2011.

It’s a good place to be in for the guys at BMW, considering the way the ongoing economic crisis has slowed own auto sales all over the world. Before it was officially released by BMW, photos of the X1 were already being circulated in the Internet where it has received a string of positive reviews from auto aficionados everywhere.

Continued after the jump.

While the European launch is still scheduled for next month, BMW is already in the works of producing a crossover US version for BMW-loving Americans.

Taking in the tradition of another BMA SUV – the X3 – the X1 will be offered in a number of different set-ups based on an individual’s preference. Short of saying, the X1 is going to be like the X3’s kid brother – a slight smaller version of the X3 that also comes with traditional rear-wheel drive and xDrive all-wheel drive, not to mention a gasoline engine and three diesel choices.

What remains unclear for the X1’s American version is the debate on what kind of engine and transmission is going to be put on the SUV. The unstable and ever-changing nature of the US market will inevitably play a part in BMW’s decision on how the X1->ke2474 is going to be packaged for the US audience.

In any case, BMW has, at the very least, a year to make up its mind. For now, it has its hands full on the X1’s European introduction in Geneva in September.
