The next-gen BMW X5 has been a long time coming . Though the current F15 generation has been in production since the middle of 2013, we've seen spy shots of the new model for nearly two years at this point. While the new X5 will no longer be the German automaker's flagship SUV - a mantle soon to be taken by the upcoming X7 - it's still a hugely important vehicle for BMW . The current model has been a success, and this new one doesn't look like it's planning to shake up the formula.This is our best look yet. These photos were taken near the X5's production facility in Spartanburg, S.C. Some of the other prototypes were missing things like rocker panels and were sporting big, blocky bumpers. On these new models, the only things that seem out of spec are the taillights and the lower part of the front bumper. Other than that, this is as close to production as we're likely to see while still wearing camouflage.There appear to be two models in these photos. A quick look at the A pillar makes indicates that the blue model may be an M or M Sport variant while the black X5 is likely a more luxury oriented trim. The general shape remains the same, as BMW hasn't had a totally new design language in years. The kidney bean grille is larger and more upright, similar to what we saw on the X7 concept.No word on what's under the hood, but expect turbocharged six and eight-cylinder engines. Don't be surprised if we see a high-output turbocharged 2.0-liter inline four in the mix. A plug-in variant should be on offer, too. There' s also word on when we'll see the new model, but look for something official this auto show season.
