And they would be correct for classifying it as such. DCT is a AT. It isn't your traditional AT but it is still automatic.

Your right its not the same as an MT, 7DCT in manual mode is a lot faster. I have raced nothing but MT's since 1960 starting with Muncie 4SPD Rock Crushers. The DCT is not any easier to run its just runs faster which is what its all about if you are racing with it.
In fact its a lot easier to hold traction when you have both a throttle & clutch to work with than it is with just a throttle. Personally I have nothing against the current 6SPD MT's, just bought a 135IS 6MT for my daughter to replace the 330Ci ZHP 6MT. I just think there is way to much posturing about what great drivers people are because they have a MT. If people feel its necessary to take a bow because they have an MT they might want to remember the best drivers in the world, F1, use DCT's BTW BuraQ's post above is very good description of driving the DCT & how you have to workout the best way to run within your own comfort levels. We both use different techniques, BuraQ a modified launch control start in first - Me a 2nd gear start with throttle feathering, and at similar power levels were about .007 apart in 1/4 mile ET. BuraQ has since added more power & knocked off about 4 tenths but the start, which is the hard part with the 7DCT has improved by .116. If it was all that easy to just point & shoot he would be in the 11's now.

Thing to think about. Corvette uses a DCT in ALMS even though you can't get one from the factory. Reason given "our competitors can use them & we need to keep up". Next time I am out normal driving one of our 6MT's will try to keep track of my shifts. Shifting has long been relegated to muscle memory & not something I pay a whole lot of attention too. Keeping SA is what keeps me from getting bored on the street not shifting. One thing I do know is over the same route I will shift the Ranger a lot more than the 6MT BMW. Based on that I might have to be thinking about whether the BMW is more boring than the truck or not.

It's a supercharged v6.......very tuneable . 400+ is easy with Stasis....warranty too. Not much you can do to normally aspirated engines like the v8, you are right.

What sets it apart from the MT is the introduction of an electronic governor/controller that barely makes up 1/10 of the DCT transmission DCT is DCT. What do you call a vehicle that is electric driven and gas driven ? A Hybrid. DCT is exactly this, a cross class of both MT and AT having the best of two worlds and out performing both whereas the DCT has mechanical relation to the MT all day long The knowledge of MT on a road course track can be applied the same, but is more challenging with a DCT as you have to predict the DME 100% all manual shifting in a M6 DCT on a road course track Last edited by BQTuning; 01-26-2013 at 11:05 AM.. |

DCT is not a automatic transmission. Instead it is classified as semi-manual or Semi-automatic dual clutch transmission. In other words it is basically a 2 manual transmission with dual clutch housed in one assembly. It has an ability to be driven as a manual without a foot depressed clutch pedal or can be driven like a traditional automatic in certain mode.
As for its superiority over fully manual foot depressed clutch pedal transmission. There is no comparison without a doubt it is way faster in shift speeds that is not humanly possible. Also, even the best of the best fully automatic transmissions can't match its shift speeds.

This whole thing about accepting the DCT in the world of 6MT traditionalists reminds me of the 1966 Corvette. In 66 the Corvette switched to the new fangled disc breaks from the traditional tried & true drum brakes.
GM was afraid the traditionalists would hit hard against the discs so it offered a one model year option for drum brakes on the car. Over 300 were optioned with drums. The 1967 was disc only. Another interesting point disc brakes were used on 1940’s combat aircraft in WWII so they were not quite as new fangled as the traditionalists might have suggested.

The scenario applies the same, your just not seeing pass the electronic automated function. When I mention a technology with an AUTOMATIC function you obviously noticed the "mechanical" difference regardless if it has a AUTOMATIC function

Dynamic shifting is based on when I tell it to shift, not it dictating the shift Btw yes you can Rev Match in M Mode on a DCT, and yes you can down shift directly to desired gear so long as it is safe |

Btw does it look like I am using the pedals in that track vid ? No, I dont use pedals and anyone with a MT backgroup will be more prone to use the actual shifter not the pedals. Thats how you can distinguish MT driver by nature behind a DCT car |
