Design a high-quality poster featuring a sleek, modern BMW sports car

Design a high-quality poster featuring a sleek, modern BMW sports car. The car should be in motion, captured from a low-angle front view to emphasize its aggressive and aerodynamic design. The background should be a dynamic cityscape at dusk with vibrant lights reflecting off the car's polished surface. Include subtle motion blur to enhance the sense of speed. The BMW logo should be prominently displayed in the top corner with the tagline 'Sheer Driving Pleasure' in an elegant, modern font at the bottom.
