Coming from a manual car and having only had a manual for my cars it was a change needless to say. My better half wanted to be able to drive it and gets stressed out with a manual especially if there are hills. I didn't think I would care for it despite the speed of the shifts but after some time with it I found it a real joy. It is some where between a manual and an automatic. In stop and go traffic it takes finesse to be smooth like a manual and when just cruising it is an automatic. When pushing the car it is nice having the ability to fire off shifts and your hands don't need to leave to steering wheel. It is not as "rewarding" I guess you can say but then again I find that lower powered lighter cars are more rewarding with a manual over heavy higher powered ones.

I do, surprisingly. I was convinced I would get the 6MT. Drove one a few times and loved it, as I'd been driving autos for a few years. Then one day I decided to do one more test drive before pulling the trigger. Dealer didn't have any 6MTs on the lot, so I drove the DCT, and was pleasantly surprised. It's no PDK, but was much better than I had anticipated. My wife was bummed, as she was looking forward to driving stick again too, but otherwise, no regrets.

I test drove an M5C, while the the ZF 8AT is closing the gap significantly with a DCT performance whise, the drivetrain still feels more sluggish and less sharp and responsive.

That is true that the clutch disengages, but you can from 7 to 1 in one step. It's not a sequential transmission like a motorcycle, it's more of an automated manual with 2 clutches.

Unfortunately, those who have never driven a DCT equate it to their experiences with a traditional torque converter automatic and the DCT is nothing like that. If is far closer to a manual transmission than a torque converter automatic. People who say that they don't have to drive a DCT to know what it's like truly don't know what it's like.

Its better to step down gears one by one until you're in the right one. then apply throttle. Or if you're in a manual you can go 6th to 3rd with a rev match... and THEN apply throttle. going from 1500 rpm to 5000rpm in a split second and hitting your trans with all that torque usually isn't a good thing.

It is more like two automated manuals, one with the odd gears and the other with the even gears.

It is also possible to do a skip gear downshift by simply clicking the downshift paddle in rapid succession. The DCT does a nice rev matched downshift directly to the selected gear. If this causes a spun crank hub, then so would revving the engine in neutral.

When doing a rev matched downshift, there is always a lag, even on planetary automatic. The lag results from the time it takes for the engaged clutch to open, rev up the engine with the throttle and engage the required clutch. It does not matter if the second clutch is the same as the first because it takes more time to rev up the engine than it takes to change gears.

in the manual you are getting the gear you want on the downshift.. car revs up.. then you let the clutch out... then you apply the throttle.. the turbos spool and gradually build torque. It seems though that with the DCT this all happens very fast while the person is still on the throttle downshifting between gears... and you go from 100 ft/lbs of torque @ 1500rpm to 400 ft/lbs at 5000rpm almost instantly. similar to how a hard launch with boost off the line is also hard on the drivetrain.

Further, IMO, it is not the amount of torque produced that will get the crank hub to spin, but rather how quickly the engine is accelerated in revs. As long as it is the engine itself (with a stock tune) that increases its own revs, and not the drive wheels that do it, there is no risk of spinning the crank hub. As a tidbit, the original S55 tune makes ~330lb-ft of torque at 1500RPM. As a second tidbit, a ft-lb is a unit of energy, not torque; torque is measured in lb-ft .

Do you like an outcome to come down to missing a shift? Do you like minimal drivetrain loss? And I do find pleasure in beating my competition, especially if I did it in a slower car.

Objectively speaking, in 99% of driving scenarios, manual is more fun because it’s more engaging for the brain and body. IMO Driving enjoyment comes from engagement, which is 99% of the experience. The outcome is the end, winning or losing impacts ego (that 1% of the experience). You can’t tell me the actual act of tapping a paddle is more fun than rowing through the gears and using the clutch. I’m am a DCT owner and both my manual 99 M3 and 13 M3 were more enjoyable to drive than the CS. |

I wish I had DCT when I am driving at race track because I don't have to worry about money shift. Also I wish I had DCT when I take my car to a shop so that I don't worry about the shop guy money shifting it while joy riding it. (while I am fine with shop people driving it if they are good people) Except these two situations anything other than 6MT feels like I have something less.. it's weird but I had the feeling of a big loss when I had a 8speed F30.
