In recent years the manufacturers increasingly bet less by manual changes in its sports products. The automatic gearboxes used in high-performance cars are faster and more effective than any human, it must be added that the driver does not have to release the hands on the steering wheel at any time when wheel at the limit.
On the other hand we have reliability, since the manual boxes have limitations of reliability with very powerful engines. More robust manual transmissions could be used to increase its durability, but the feel of change would be far worse and also raise their weight. All this combination makes that, with few exceptions like the return of the Porsche 911 GT3 to manual change, increasingly harder to see a manual gearbox in a high performance car.
In recent years we have been aware of this change in the industry, seeing as the manufacturers they resorted especially to the changes of double clutch. In BMW you can now buy versions with 6-speed manual transmission or with dual-clutch 7-speed change. A recent statements of Peter Quintus to our colleagues from The Drive leave us open-mouthed: “La DCT had two advantages: it was light and its rate of change was increased, now much of that advantage of switching time has disappeared to Automation improve and become more intelligent“.
It is at least curious that a senior BMW make these statements when currently products of your company using this type of change. Quintus also declared that the DCT left between six and seven years of life. He praised developments receiving boxes automatic torque converter stating, inter alia, that “we are now seeing with nine and even ten speeds, automatic transmissions so there is much technology in automatic“.
The performance figures, both power and torque, in the cars of high-performance, complexity that adds in the hybrid systems and the comfort of an automatic gearbox March makes a manual almost impossible to see in a new supercar. The oddest thing is that, according to BMW, exactly the same reasons “will kill” the double clutch in the torque converter.
