DSG and SST are two completely different types of transmissions. SST isn't an Automatic, no spin necessary.

 

Both DSG and SST are both dual clutch semi automatic sequential transmissions.

 

They are identical transmissions. Both will work in full auto mode, or you can "shift" for your self by pressing the gear shifter or pulling on shift paddles behind the steering wheel.

 

Very good point. I currently work for Audi and the DSG tranny is pretty neat. But, you're right, at the end of the day it's still an auto and after driving it for a couple days it gets very boring very fast. Then, your left without any engaging driving experience. Same thing will happen with the SST. Will seem cool for the first week and then people will want the engagement of a manual. Oh well...let them figure it out.

 

The good thing about DSG/SST is that you can concentrate more on going fast. Manually shifting and messing with the clutch is a distraction which leads to slower lap times.

 

ya, i seen this as well. I hope they change that for the US spec version. Even though new transmissions are up to par with manuals, i want the real feel of manual.

 

How can they be identical when one has a clutch and the other one doesn't?

The SST transmission uses a clutch that is controlled by a computer. Same as a manual transmission but instead of pressing in the clutch with your foot, the clutch is controlled electromechanically. The SST transmission also uses gears to determine the specific drive ratio.

The DSG transmission doesn’t have gears or a clutch, and no shift points. You do not feel the gears shifting in a DSG type transmission in auto mode. It’s strange but the car feels as though it never changed gears. SST or twin-clutch transmissions do not exibit that trait.

The following was jacked from the web:

There are several types of CVTs, most cars use a pair of variable-diameter pulleys, each shaped like a pair of opposing cones, with a metal belt or chain running between them. One pulley is connected to the engine (input shaft), the other to the drive wheels (output shaft). The halves of each pulley are moveable; as the pulley halves come closer together the belt is forced to ride higher on the pulley, effectively making the pulley's diameter larger. Changing the diameter of the pulleys varies the transmission's ratio (the number of times the output shaft revolves for revolution of the engine), in the same way that a 10-speed bike routes the chain over larger or smaller gears to change the ratio.

Dude, just because both transmissions have paddles and fully automatic modes DOES NOT make them the same. That is a ridiculous oversimplification. If that were the case then you could say that the Ferrari F430 transmission is the same as the standard lancer transmission. Both have paddles and automatic modes? But in reality the two transmissions are completely different.

 

Dude...I work for Audi. Don't post about stuff you don't understand. The Mitsu SST is a knock-off of the Audi DSG. They are both a dual-clutch setup controlled by a computer to control shifts.

Where did you pull that crap from the web?

Here's the information on DSG straight from Audi's website...

Or, read the 5th paragraph in this article...

adambl03 is right. DSG and SST are basically the same thing. Maybe Mitsu tuned it a bit better? We'll see.

 

Possibly. Audi's tranny is pretty dialed-in and that comes from years of racing with that transmission. Mitsu doesn't have any experience with a transmission like this at any level of racing (at least that I'm aware of). You're right, we'll see what this thing can do when it comes out.

 

I'm confusing DSG with CVT. Sorry. Either way, they both blow away conventional manuals. And I do understand :- )

 

Agreed, basically the same thing, but get away from the word "automatic" with regards to this transmission. It's not, it is an automated, there is a difference, and people obviously need to learn that.

Automatic transmission has a torque converter, hydraulic computer, and planetary gears, no synchroes. No shifter. http://auto.howstuffworks.com/automa...ansmission.htm

Automated Manual transmission has an no torque converter, an electronic computer, and synchroes. No shifter. and the VW/Audi DSG, both use dual wet clutches, and sequential gearing. The automated manual tranny is not a CVT. http://auto.howstuffworks.com/dual-c...ansmission.htm

 

Actually, they're more or less the same design.

 

CVT != DSG.
