Technology

As more advanced technologies are being employed to improve fuel economy, the sound character inside the vehicle is changing. For example, an engine that deactivates 3 of its 6 cylinders to reduce fuel consumption sounds noticeably different from when it's operating on all 6 cylinders. A gasoline-electric hybrid vehicle sounds different depending on which engine is operating.
