Geometric variable turbocharged gasoline engine is a patent of Porsche.
The valve adjustment technology is represented by Japanese cars: the most ingenious structure is Nissan's continuously variable valve lift technology (VVEL), and other manufacturers such as Toyota's VVTi, Honda's VTEC and BMW's Valvetronic are similar.
The latest technology of gearbox is double clutch direct shift gearbox (DSG), which is also a patent of Volkswagen Audi, so Porsche later gave its similar products a name (PDK), commonly known as fast running. Similar products from other manufacturers are also coming out.
Now the most advanced core technology of internal combustion engine power belongs to Volkswagen Audi.
