Create an urban-adventure-ready BMW X5 M with sportscar elements: Add a front fascia characterized by an aggressive splitter for enhanced downforce, deep-cut side vents for improved aerodynamics, and a set of rear performance tires wrapped around sporty rims. Color the SUV in a gradient from moonstone pearl to electric lime green, capturing the essence of city luxury and racetrack prowess as it stands prominently on a neon-lit avenue.  --ar 1:1
