Lowering noise, vibration, and harshness (NVH) levels is key to achieving a smoother, quieter ride and drive. And as quieter electric motors replace combustion engines, managing ambient noise levels within passenger vehicles becomes not only more important—but an increasingly challenging engineering feat. Even the smallest variations during manufacturing can affect NVH levels. But through extensive research, design, and rigorous product testing, Dana’s products achieve significantly lower NVH levels than competitor products.
