Porsche has filed a patent for a shift-by-wire transmission gear selector that can operate as both a traditional manual and a standard automatic. The design is similar to the transmission used in the Koenigsegg CC850 but focuses on an electronic driver interface rather than the physical gearbox. The system allows drivers to switch between an H-pattern manual mode with a clutch pedal and a conventional automatic drive mode. While the system uses electronic signals rather than a physical linkage to the gearbox, electric motors and springs create the tactile resistance and feedback of mechanical gear shifts. However, developing and implementing such a system for mass-market sports cars could pose a significant challenge.
