Curious to know also how much of the sounds going through inside the interior is synthetic vs real sounds

BMW will probably release an M Performance Exhaust later on (most likely in cooperation with Akrapovic)

This is the M Performance Exhaust.

my big question is: if you leave it totally stock, take it to the track and it breaks... will BMW fix it under warranty?

The F10 was muted. This one seems just right.

I had the last E63s. It never droned, despite having a kickass sound when getting onto the throttle.

Some other things to pay attention to in this footage:

Gear Changes, including manually selected, in Sport+ mode are FASTER than DCT.

The shift @35 seconds (which has been singled out here already), is to demonstrate the car won't up-shift at redline in manual mode.

The shift sequence @40 seconds is as follows

Launch Control 1st -> DOUBLE Up 2nd -> 3rd -> 4th.
The time it took to go from 1st to 3rd is the same time DCT takes to perform a max performance upshift.

I'm sorry but there is no chance a torque conv. Automatic will change gears faster than a true performance DCT no matter what the BMW M engineers try to spice up.

In a performance DCT car you actually have zero power loss between shifts as the next gearset clutch is grabbing as the current gearset clutch is clutching off simultaneously. In the newer performance DCT's like mclarens not only do you have no loss in power but you actually get a brief surge/boost of power from the inertia. You can read all about it in mclarens 650s press release.

These new age automatics are blazing fast but can not touch true performance DCT's at the upper echelon. If these automatics could shift faster and even shift two gears faster like you are claiming we would see them on all the HyperCars and even super cars. It's simply not true no matter what Bmw spices up.

Chevy made the same claims with the 8 speed automatic in the z06 being 30% faster than the pdk in the 911 but in reality it wasn't even close.

I'll take that bet.

bruh, is that your real counter? I have the exact same granite. And thanks for finding my stack of money that I lost...PM'd you my paypal.

Mine, no. I have better taste than bargain Chinese granite.

thanks for confirming that I don't have good taste.

Prove it. Stack of some cash isn't impressive but some cold hard facts proving me wrong would be.

M Sport Sounds Good will be even better with Downpipes

It wasn't meant to be impressive. I rather like the return on the long-shot odds this subject would offer if an actual financial wager was placed.

Facts:

Dual Transmission Gear Box overlapping is not 100% without power interruption. There's always some.

The inertial Lightning Shifts are not unique. The DCT updates beginning with the F10 have this feature.

The 8L90 was faster than the Midrange PDK version used for testing. It is not faster than PDK with Sport Chrono or PDK-S.

As described for the ZF 8 speed planetary Gen 2 and newer...

"The shift elements enable changing gears without traction interruption. For this reason, all gearshifts (from first to eighth gear and back) are performed as overlapping gear changes. During the shift process, the "transmitting" clutch remains actuated with a lower pressure value until the "receiving" clutch can transmit the torque."

The shifts are not the Torque Converter, but with the internal clutches and brake sets.

The speed is courtesy of the worlds 2nd fastest shifting gearbox, the ZF 8P45R (8HP without Torque Converter as daily street use isn't a factor), that allowed an advanced software and electronics architecture for planetary gearset transmissions to be developed, tested, and ultimately incorporated.
