Why We Never See Dual-Clutch Transmission on Race Cars

It is a well-known fact that dual-clutch transmissions take precedence in the performance car market. But why are they ignored when it comes to actual racing?

To explain why, Nate Vincent of FCP Euro created this great video where he compared his old DSG dual-clutch transmission to his new sequential transmission.

"We are going to be talking about the differences between a DSG and sequential gearbox in a Golf GTI TCR," says the beginning of this video.

The most notable and most important difference is weight. The sequential weighs 100 pounds less than the DSG. The DSG tends to be heavy because it has two shafts. This makes a big difference in racing.

In addition, the gearbox is tagged which means no one can change any of the settings without Audi motorsports knowing. The gear ratios are also different, they are closed in. 

The gearbox also has unequal axel shafts. But, notes Vincent, the big difference is the way the gears engage. The gearbox uses dogs rather than synchronizers which means the driver can shift better.

If you want to hear more differences make sure to watch the video. Vincent spares no detail in this precise and clear description. We promise you will finally know the difference between a DSG and a sequential.
