The BMW i7 boasts a surprisingly low drag coefficient, which significantly contributes to its impressive efficiency and extended range.
Aerodynamic Efficiency of the BMW i7
Despite its somewhat angular and robust exterior design, the BMW i7 is engineered with remarkable aerodynamic efficiency. This meticulous design results in a very low drag coefficient, a key factor in its performance, especially for an electric luxury sedan.
The exact drag coefficient for the BMW i7 is 0.24 Cd. This low figure is crucial for an electric vehicle, as reduced air resistance directly translates to lower energy consumption and a greater driving range on a single charge.
| Vehicle Parameter | Value | Unit |
|---|---|---|
| Drag Coefficient | 0.24 | Cd |
This excellent aerodynamic performance allows the i7 to make optimal use of its substantial battery capacity. For instance, testing has demonstrated that at speeds as low as 37 mph, the i7 can achieve a substantial range, exceeding 497 miles on a single charge. This highlights how effective aerodynamic design, combined with a large battery, enhances real-world driving capabilities.
By minimizing air resistance, the BMW i7 reduces the power needed to maintain speed, especially at higher velocities, thereby improving overall energy efficiency and contributing to its remarkable long-distance travel capabilities.
