Porsche has applied for patent protection of a new transmission system, designed by its engineers, which could “reconcile” lovers of classic manual gearboxes and proponents of modern automatics. The patent, the details of which were published in early March, envisages a single shifter that would be capable of operating in two different modes.
This means that in automatic mode the lever would be used to select the basic driving functions (RND), while with a simple switch it turns into the classic H-range of gears and enables manual “jumping” – for those who just lack that for a complete feeling of sporty driving. It is important to note that this is a “shift-by-wire” solution, which means that the lever does not have a direct mechanical connection with the gearbox, but only sends signals to it electronically. The transmission is essentially an automatic or conventional dual-clutch type, but Porsche’s approach could simulate the tactile and mechanical feel of shifting gears without the complexity of a traditional manual gearbox.
Something similar already exists
The concept of a combined gearbox is not entirely new in the world of sports cars. A similar solution has already been implemented by the Swedish Koenigsegg in its CC850 and Chimera models, using extremely complex electronics to simulate the operation of the clutch and synchronizer. However, while Koenigsegg produces its solutions for multi-million dollar unique models and can afford the complex solution of a 9-speed gearbox with seven clutches, Porsche faces the challenge of making such technology cost-effective for a wider portfolio of large series models, such as the 911 or 718 lines.
The development of such a hybrid interface carries significant technical and financial obstacles. Porsche would have to adapt the existing PDK technology or develop a completely new system that would justify its price in series production. Analysts therefore question whether such a solution will ever be used more widely or will remain reserved exclusively for a narrow circle of enthusiastic buyers and limited series – since we know that Porsche is already dealing with a decline in income and especially profitability.
The motivation for the development of this patent lies in the desire of the manufacturer to keep the driver engaged in the era of increasingly powerful electrification and automation, that is, to continue looking for a way to reconcile maximum performance with an emotional driving experience. Although the patent registration does not guarantee serial production, it clearly outlines the direction in which the German brand is thinking. A system that enables comfortable city driving in automatic mode and engaged driving on the open road via a simulated manual gearbox could be key to preserving the brand’s identity in the coming years.
