Subject: Electric sedan chassis with a large-capacity blue on-board power battery installed in the center of the bottom, paired with black sports front and rear wheels and silver chassis mechanical structure, presenting the core power architecture of a pure electric vehicle overall, with a blue transparent outline of the vehicle. Scene: Pure black deep background, highlighting the main structure of the car chassis and power battery, no extra clutter to interfere. Style: Tech-savvy automotive engineering promotional image style, leaning towards professional and realistic automotive industrial design visual effects, clearly displaying core electrification components. Tone: With deep black as the base, the power battery uses high-saturation blue, the chassis and mechanical parts are silver-gray metallic texture, the wheels are black, the overall color matching is simple and highlights technological attributes. Lighting: Using uniform and soft tone, highlighting the cold texture of metal parts and the bright blue appearance of the power battery, no strong light-dark contrast, clearly showing the structural outline of each component. Composition: Horizontal center composition, the car chassis components extend along the horizontal midline of the画面, forming a stable visual axis, the power battery is located at the visual center of the画面, fully presenting the front and rear layout. Purpose: For displaying the power architecture design of pure electric vehicles, highlighting the advantages of core electrification configurations.
