Porsche Patent Envisions ‘Tunnel Mode’ to Amplify or Mute Sound in Tunnels

The idea appears only in a WIPO application with no stated plan for production.

Overview

  • Automotive outlets report that CarBuzz spotted the WIPO filing describing camera-based tunnel detection that preps the car before entry.
  • For combustion models, the system would drop windows, select a lower gear, switch to a sport setting and open active exhaust flaps to heighten acoustics.
  • Electric Porsches would boost synthetic powertrain sounds derived from combustion models for a more pronounced in-tunnel effect.
  • A comfort alternative would keep windows closed, choose a relaxed drive mode and close exhaust flaps to reduce noise.
  • Convertible drivers would receive prompts to lower the roof while climate controls adjust to maintain cabin comfort, and coverage notes criticism over potential nuisance and enforcement issues.
