Ebrake with DCT

How is that possible the driver pulls Ebrake while driving DCT? Is it possible to use Ebrake while in gear?
Can you enter drift using the Ebrake having DCT?

I don't think anyone thought you were serious. The DCT transmission has no relation with the ebrake.

Yeah, with DCT M3, you just turn the steering wheel & floor it, out come the back end, whether you pull the e-brake or not.

Actually, I suspect that the e-Brake doesn't lock up the rear wheels. All it does is in essence "brake" in the middle of the corner thus effectively shift the weight up front and force the chassis to rotate (oversteer) against its will.

If it DOES lock up the rear tires, the end result would be, since the DCT is fully connected to the engine via one of the two clutches, that the engine would stall out (or the clutch would burn up).

The problem is releasing the ebrake in case it locks. I wouldn't even use it.

As OC3 said...put it in 2nd, DSC off and floor it. You'll have no problem getting the back end to come around...come around quickly it will!

The biggest problem you'll have is keeping the car sideways. The E9X M3 handles very well and will want to get the car straight. I had an ex-formula drift guy drift my E90...even he couldn't keep the car really sideways. He was amazed at how well the car handled.

Really? Wow! I did know that till now. Thanks for your explanation

I thought that the DCT could in fact have some input from the Ebrake sensor and declutch the drive. Otherwise it looks like these guys (driver and the pasenger) have no clue what they are doing. Just creating stress on the drivetrain. Ebrake fighting with the engine.

I can believe that what the passenger did in the middle of a fast turn had no effect however the last part of the video wanders me most.
The driver clearly entered donut by using Ebrake.

I have a drifing car (E36 M60B40) and know a little about drifting but would never try on my own M3 pulling Ebrake with DCT. It should just make a lot of stress on the drivetrain but never lock the rear wheels.

You can keep the car sideways as long as you have tires unless you have to go into the 3rd gear. Then the car lacks power.

Using the e-brake to get the car sideways is only one of many ways. You can also do clutch-kick, or sudden weight transfer (flick the car), or just power it, etc.

I think e-brake is used typically in under-powered cars; and in cars with plenty of power, done by drivers who are used to using the e-brake.

If you have a DCT M3...that leaves you with one option...the scandavian flick. Should be the Asian flick if you ask me.
