The impact of the 48V system extends far beyond just fuel economy. Its real potential lies in powering advanced chassis and comfort systems that were previously impractical or too inefficient with a 12V electrical system. The higher voltage allows for more power with less current, leading to smaller, lighter wiring and more responsive actuators.

Key enablers include:

• Active Roll Stabilization: Electric motors can almost instantly counteract body roll in corners, providing both sporty handling and ride comfort.

• Advanced Suspension: Fully active, hydraulic-free suspension systems (like Audi's predictive active suspension) use 48V to power powerful pumps that adjust each wheel individually.

• Brake-by-Wire: 48V provides the necessary energy for swift and precise electro-hydraulic or electro-mechanical braking, essential for integrating regenerative and friction braking seamlessly.

FAQ

Q: Does this mean 48V is only for luxury cars?A: Initially, yes. But as the cost of the technology decreases, these advanced chassis systems are trickling down into more mainstream segments, making high-end comfort and safety features more accessible.

Q: Is 48V a dead-end with the rise of full EVs?A: Not at all. It remains the most cost-effective way to significantly improve the efficiency of internal combustion engines, which will be part of the global fleet for years to come. It's a crucial transitional technology.

48V is the key that unlocks a new level of dynamic performance and refinement, regardless of the powertrain.
