The modern, elegant exterior represents a deliberate counterpoint to the dynamic flair of the driving experience. The perfectly resolved Gran Coupe proportions create an authentic, modern and confident appearance. Another distinctive area is the wheel rims. These have been designed exclusively for the BMW Concept i4 and blend aerodynamic and lightweight design; smooth – and therefore aerodynamically optimized – surfaces contrast with ultra-low-weight, high-strength spokes. The rims extend the car’s palette of colors and materials, emphasizing its luxurious overall character.
