Tjet produces 110 bhp for India as Fuel quality is a issue here or may be they want it to be more FE car, we checked it at auto expo today.
It might take some time for them to actually launch it.

It not fully automatic. The technology is a bit different from the automatic.
This dualogic actually give better performance than manual transmission. So can put it this way, no clutch change..in fact no clutch lever. Automatic clutch changes and you get manual transmission performance.

It has more torque, so actually will be faster in straight-line compared to ANHC thought it is only 108 bhp.

You can't change from Automatic to Manual and vice versa. This option is not there in Duallogic. You can imagine this way; Using paddle shifts to change the gear without pressing the clutch and getting the manual transmission performance.

Sounds too good to be true. I think this was started in Alfa Romeo named as 'Selespeed' feature.

This will give better fuel efficiency probably 1 Km more than the manual transmission driven cars.

I was thinking the same way yesterday. I did not know what dualogic is. Impressive.

Has anyone seen pictures of what the dualogic transmission looks like (in the cabin area I mean). Do the interior pics show this?

Per Wikipedia, it is actually semi-automatic transmission.
Marketing names:
# Twin Clutch SST - Mitsubishi
# Dual clutch transmission (DCT), a generic term - Volkswagen Group, Bugatti, Koenigsegg
# Direct-Shift Gearbox (DSG) - Volkswagen Group: SEAT, Skoda Auto, Volkswagen
* S tronic - Audi
# Dualogic - Fiat
and the like...

Only the exterior picture of Linea that reads Linea Dual Logic. Check here Fiat Linea 110 bhp turbo petrol, Punto 90 bhp diesel & Punto CNG-petrol flex fuel on show at Auto Expo 2010 - Motoroids.com

Probably this link will answer your query Dualogic Gear lever

This is not the photo from 1.6 Tjet Linea, but just to get the idea of Dualogic transmission.

Here is how Dualogic works, Courtesy :italiancars.net

The DuaLogic gearbox, which is available on the Fiat Punto with the 1.4 petrol engine as well as the Turbo Diesel Punto 1.3 JTD, is technically described as a sequential manual gearbox, which means it has a conventional clutch and gearbox, so there is no power-sapping torque converter and hydraulic gears. Instead there is small, light actuator unit to operate the clutch and move the gears, plus a highly intelligent computer.
Thus, the DuaLogic equipped Punto has the performance and economy of the manual car as a starting point, unlike a conventional automatic which is always at a disadvantage to a manual gearbox given its weight and power-consuming technology. To this already efficient system is added a computer that knows the engine to which it is connected inside-out. The computer ensures that the gearbox is always in the most effective gear for the performance required, maximising both performance and economy capabilities. Indeed, the Punto DuaLogic even knows if it is going downhill or climbing a hill and adjusts its changing patterns appropriately!
With the DuaLogic taking over the operation of the gearbox and the clutch, driving is easier and simpler. The driver has the choice of placing the Punto DuaLogic in automatic or manual modes. In automatic mode, DuaLogic does all the work, selecting the gears, operating the clutch and getting the best economy and performance. The driver can also select normal mode or economy mode, with, as the name suggests, the latter selection ensuring that the Punto extracts every the maximum energy out of every last drop of fuel.
DuaLogic doesn’t just blindly change gears. It has full fuzzy logic, so it can adapt to the driver’s style, matching his changing demands, both his style and changing road conditions. Another feature of the DuaLogic is its ability to assess vehicle deceleration and adjust downshifts.
In semiautomatic mode, for example, the system allows downshifts, particularly when the driver demands a lower gear to take a corner at speed during a sporty drive. In automatic mode, the system anticipates the downshift to ensure the driver can always call on the most appropriate speed to maintain the required comfort level or fuel saving.
With the DuaLogic gearbox in automatic mode, its robotised electronic management system allows the gears to be changed at the time of maximum engine performance. This makes it possible to exploit all the power and torque of the 1.4 petrol and 1.3 Multijet Turbo Diesel engines and achieve a distinct improvement in acceleration over a manual gearbox.
However. This is an Italian car; therefore DuaLogic has a manual mode where, using the gear lever, the driver can self-select gears to get the maximum pleasure out of driving the Punto.

Sounds great. Anyone knows how reliable it is? Heard many stories here about the DSG failing in the VW/Skoda stable.

I remember i read in some international FIAT forums complaining about this Dualogic gearbox. It has got some reliability issues just like DSGs. But FIAT seems to have been working on this and solving these problems.

Nevertheless,It has got lot of fans as well. Love to see it on Indian linea and Punto (may be in diesel variants as well)
