The 7 speed dual clutch transmission DQ200 offers convenience and switch without interruption of the traction as the same as the manual gearbox. It is designed for engines up to 250 nm of torque at the Lavida, Golf, Octavia, Sagitar and Touran etc. The direct-shift gearbox related to fuel consumption is still at the same level with the compared transmission, and the fuel consumption of dual clutch transmission is lower than the manual transmission by technical innovation. The reduction of fuel consumption can be a huge contribution to the reduction of emissions as well as environment protection.
The new dual clutch transmission DQ200 of Volkswagen have two world premieres:
- the first seven gears for front transverse installation
- the first dual clutch transmission with dry dual clutch
The dry dual clutch has a significant impact on the entire transmission concept. The new transmission concept can improve the work efficiency once again compared with the manual transmission. The improved efficiency can be a huge contribution to the reduction of energy consumption and emissions.
The 7 speed dual clutch transmission DQ200 represents another milestone in the transmission strategy of Volkswagen Group, and carries on the technological advance of Volkswagen.
Audi valvelift system is one of the major innovations of Audi. It regulates the lift of the valves in two stages depending on lead and engine speed. The system thus increases torque while also reducing fuel consumption.
Two versions for the AVS system are available: Gen-3 and B-Cycle. The GEN-3 AVS is similar to the one already used in the second generation of the EA888 1,8 and 2,0l petrol engines, while the B-Cycle AVS version is being used in the new 2.0 TFSI ultra engine. The rollout started with the 2016 Audi A4.
In the latest generation 2.0 TFSI ultra, the B-Cycle AVS varies the lift of the intake valves. It reduces slushing losses in the combustion chamber and also ensures that the optimal flow of the exhaust gas is directed to the turbocharger. Both versions have a simple compact and lightweight system design making use of so-called cam pieces-sliding on the camshaft
