设计理念与灵感
- 核心目标：Sabino 希望打造一台 “未来感十足的宝马”，既保留品牌的耐力赛车基因，又用极具冲击力的未来主义车身进行重构。
- 风格溯源：设计融合了经典咖啡赛车（Café Racer）的侵略性轮廓与赛博朋克（Cyberpunk 2077）的未来美学，部分媒体甚至将其与钢铁侠头盔的几何线条联系起来。
- 功能优先：这不仅是视觉实验，更是对 “形式追随功能” 的极致演绎 —— 每一处线条都服务于空气动力学与操控性。
关键设计特征
- 结构与材质
- 采用传统钢管车架，搭配大量碳纤维部件（后摇臂、前后挡泥板、车身覆盖件），实现轻量化与强度的平衡。
- 外露的 trellis 车架与厚重的下导流罩形成强烈视觉对比，既展现机械美感，又优化了空气动力学。
- 车身与姿态
- 长轴距、低重心的设计，配合宽大的后轮与纤细的前轮，营造出蓄势待发的运动姿态。
- 座椅与油箱齐平，脚踏位置后移，迫使骑手采用前倾的战斗坐姿，强调纯粹的驾驶乐趣。
- 细节与标识
- 宝马 Logo 巧妙地融入空气滤清器顶部，而非传统的车身侧面，保持了整体的简洁性。
- 排气系统与车身无缝融合，LED 头灯与尾灯则采用未来感十足的边缘发光设计。
配色方案
- 提供多种双色调涂装：
- 金属银与亮黄（图中主色调），致敬宝马经典赛车涂装。
- 冷白与黑，适合日常通勤场景。
- 金属银与浅蓝，呈现科技感与未来感。
性能与定位
- 设计初衷是一台专注于敏捷性的超级跑车，既能在城市车流中灵活穿梭，也能在赛道上释放极致性能。
- 虽然概念图中保留了传统内燃机与排气系统，但设计师也曾设想过将其作为电动摩托车的载体，以适应未来的可持续出行趋势。
BMW Motorrad CH4 设计草图与渲染图对比清单
1. 早期概念草图阶段
- 核心探索：设计师 Sabino 首先通过大量线稿，探索了三种截然不同的方向：
- 咖啡赛车复古风：保留了经典的油箱与座椅比例，但线条更锐利。
- 赛博朋克机甲风：强调外露的机械结构与棱角分明的车身面板。
- 流线型未来风：追求极致光滑的空气动力学外形，弱化了机械感。
- 关键决策：最终选择了 “机甲风” 作为主方向，因为它最能体现宝马摩托车的力量感与技术感。
2. 3D 建模与结构推敲
- 车架与悬挂：在 3D 模型中，重点优化了 trellis 车架的几何结构，确保在视觉上足够粗壮，同时保证了轻量化。后摇臂的设计经历了多次迭代，从最初的实心结构，演变为最终的镂空碳纤维结构，以减轻簧下质量。
- 人机工程学：通过调整座椅高度、脚踏位置和车把角度，确保了前倾的战斗姿态，同时保证了长时间骑行的舒适性。
3. 材质与光影测试
- 材质对比：设计师测试了多种材质组合，包括全碳纤维车身、金属与碳纤维混合、以及哑光与亮面涂装。最终确定了 “金属银 + 亮黄” 的组合，因为它能在不同光线下都呈现出丰富的层次感。
- 光影表现：通过调整环境光和反射，突出了车身的曲面和棱角，强化了未来感。
4. 最终渲染图与设计定稿
- 视觉焦点：最终版本将宝马 Logo 置于空气滤清器顶部，成为视觉中心。
- 细节完善：排气系统的造型、LED 灯组的边缘发光效果、以及轮胎的胎纹设计，都在最后阶段进行了精细调整，确保了整体的和谐与统一。
Product Design of BMW Motorrad CH4 Supercar Concept Car
NINEIDEA: This product design of the supercar concept car created by Dutch designer Sabino Leerentveld, officially known as BMW Motorrad CH4, is an unofficial independent design project aimed at exploring the future shape and performance boundaries of BMW motorcycles.
Design concept and inspiration
- Core goal: Sabino aims to create a “futuristic BMW” that retains the brand’s endurance racing genes while being restructured with a highly impactful futuristic body.
- Style tracing: The design blends the aggressive silhouette of the classic Caf é Racer with the futuristic aesthetics of Cyberpunk 2077, with some media even linking it to the geometric lines of the Iron Man helmet.
- Function first: This is not only a visual experiment, but also the ultimate interpretation of “form follows function” – every line serves aerodynamics and maneuverability.
Key design features
- Structure and Material
- Adopting a traditional steel pipe frame, coupled with a large number of carbon fiber components (rear rocker arm, front and rear fenders, body coverings), to achieve a balance between lightweight and strength.
- The exposed Trellis frame creates a strong visual contrast with the thick lower air deflector, showcasing both mechanical aesthetics and optimizing aerodynamics.
- Body and posture
- The long wheelbase and low center of gravity design, combined with the wide rear wheels and slender front wheels, create a ready to move posture.
- The seat is level with the fuel tank, and the foot pedal position is moved backwards, forcing the rider to adopt a forward leaning combat posture, emphasizing pure driving pleasure.
- Details and Identification
- The BMW logo cleverly integrates into the top of the air filter instead of the traditional side profile, maintaining overall simplicity.
- The exhaust system seamlessly integrates with the body, while the LED headlights and taillights adopt a futuristic edge lighting design.
color scheme
- Provide multiple dual tone coatings:
- Metallic silver and bright yellow (the main color tone in the picture) pay tribute to BMW’s classic racing livery.
- Cold white and black, suitable for daily commuting scenes.
- Metallic silver and light blue present a sense of technology and futurism.
Performance and Positioning
- The original design intention is a supercar focused on agility, which can flexibly shuttle through urban traffic and unleash ultimate performance on the track.
- Although the concept diagram retains the traditional internal combustion engine and exhaust system, the designer has also envisioned using it as a carrier for electric motorcycles to adapt to future sustainable travel trends.
BMW Motorrad CH4 Design Sketch and Rendering Comparison Checklist
- Early concept sketch stage
- Core exploration: Designer Sabino first explored three completely different directions through a large number of drafts:
- Coffee racing retro style: retaining the classic fuel tank to seat ratio, but with sharper lines.
- Cyberpunk mecha style: emphasizing exposed mechanical structures and sharp body panels.
- Streamlined Future Style: Pursuing the ultimate smooth aerodynamic shape, weakening the mechanical feel.
- Key decision: We ultimately chose “Mech Wind” as the main direction because it best embodies the power and technology of BMW motorcycles.
- 3D modeling and structural refinement
- Frame and suspension: In the 3D model, the geometric structure of the Trellis frame was optimized to ensure that it is visually robust and lightweight. The design of the rear rocker arm has undergone multiple iterations, evolving from a solid structure to a final hollow carbon fiber structure to reduce the weight under the spring.
- Ergonomics: By adjusting the seat height, foot pedal position, and handlebar angle, the forward leaning combat posture is ensured, while also ensuring comfort for long-term cycling.
- Material and Light and Shadow Testing
- Material comparison: The designer tested various material combinations, including a full carbon fiber body, a mixture of metal and carbon fiber, and matte and glossy coatings. The combination of “metallic silver+bright yellow” was ultimately determined because it can present a rich sense of layering under different lighting conditions.
- Light and shadow expression: By adjusting ambient light and reflection, the curves and edges of the car body are highlighted, enhancing the sense of futurism.
- Final rendering and final design draft
- Visual Focus: The final version places the BMW logo on top of the air filter, becoming the visual center.
- Exquisite details: The shape of the exhaust system, the edge lighting effect of the LED light group, and the tire tread design have all been finely adjusted in the final stage to ensure overall harmony and unity.
