BMW 性能社交媒体海报

Create a 4:5 vertical social poster in ultra high resolution, 8K print quality sharpness. Use the {argument name="car model" default="BMW car"} from the reference image as the main subject and use the background structure/composition from the reference image, but transform it into a BMW themed design. Replace all black tones with a flat {argument name="background color" default="high-saturation BMW blue"} background. Keep the same layout, spacing, visual balance, and poster composition from the reference image. Background should use a smooth gradient from slightly lighter electric blue at the top to deep navy blue at the bottom. Add subtle grain texture (2 to 3%) and faint rectangular overlays (2 to 4% opacity). Keep it clean, graphic, premium, and non-realistic. Add a soft contact shadow under the car. Use the same BMW from the reference image, changing only the {argument name="paint finish" default="matte frozen blue"} or deep metallic navy. Keep the original body shape, wheels, stance, and design details from the reference image. Show the car in a rear 3/4 perspective matching the reference image angle exactly. Use a slightly elevated camera angle. Position the car slightly right of center. Include visible carbon roof, aggressive rear diffuser, sharp controlled reflections, and subtle brake details. Keep composition identical to the reference image: Top: branding Middle: giant type Center: car overlapping text Bottom: editorial block and specs Typography: Primary text: “BMW” Ultra condensed bold sans serif, tall vertical scaling like the reference poster. Color deep navy or near black. Static text with no distortion. Acts as structural backdrop. Secondary header: “BMW M4 G82” Thin font with wide tracking. Logo area: BMW roundel centered above. Editorial block: Headline: “BMW — Where Driving Becomes Instinct” Body copy focused on: driver connection control performance precision Use the same boxed editorial layout as the reference image. Background faded text: “M4” large scale with 3 to 5% opacity behind the box. Bottom left: “ M4 G82” Bottom right specs: 405 kW / 550 PS 3.4 s 307 km/h Lighting should be clean studio lighting with sharp but controlled highlights. Color grading should use deep blues, high contrast, clean blacks. Camera lens: 50mm, slightly elevated rear 3/4 angle. Mood: Performance. Precision. Driver focus.
