With BMW already testing the next-generation X5 hidden underneath present-day body panels and camouflage, it's certainly not too early to speculate about its design language.
This rendering uses a Vision Future Luxury-inspired front end, which is a clear departure from what the current model looks like. As for the rear, its reminiscent of the 7-Series with that horizontal design element, though the taillights are slightly larger - which does work seen as how this is an SUV.
