Curious with this car a lot. This could be next BMW car. Called the X6 M. This spy photo showed, this car is specified by 4,4 liter V8 engine and could run more than 500hp. Its just the prototype and haven’t test drive yet. Beside the X6 M, the rumor also said, BMW will also produce the sibling of this with V10 engine version and will boast 507 hp. We are waiting.
