What Do 9-Speed Tiptronic and 7-Speed Dual Clutch Mean?
1 Answers
Here is the related introduction about 9-speed tiptronic and 7-speed dual clutch: Different gear forms: The 7-speed dual clutch transmission adopts a manual gearbox, cooperating with an electronic control computer to simulate the automatic transmission operation mode; while the 9-speed tiptronic transmission is an automatic transmission, using computer control to simulate the manual mode. Different clutch forms: The 7-speed dual clutch transmission uses wet dual clutch plates, which alternately work for gear shifting, while the 9-speed tiptronic transmission uses a wet clutch plate group to control the gear combination operation of the transmission. Different fuel-saving capabilities: The 7-speed dual clutch transmission actually uses the gear set of a manual transmission, with no power loss, naturally improving fuel economy, while the 9-speed tiptronic is an automatic transmission, where the hydraulic torque converter still loses engine power, and even with the addition of a mechanical lock-up system, it will still increase fuel consumption at low speeds.
