Results 1 to 10 of Thread: Fiat Dualogic - Long Term reports. Right, thought I'd organize my ramblings about the new into something a little more structured.

So here goes on possibly the worlds first Fiat 1. No rattles, squeaks or unwanted behaviour. The engine seems to be bedding in nicely, it is more eager to spin up than it was when first picked up, and the dualogic gearbox seems to be learning everyday how to change gears more smoothly.

I know the engine is brand new and not run in yet so I wasn't expecting great things on the fuel consumption front, and the first fill up revealed a not brilliant fuel consumption of 41mpg. Not bad, but I'm hoping for better in the coming months. When the car was picked up the engine felt tight and unwilling to rev with any degree of freeness. Now with kms under its belt the car feels completely different, it is much more willing to spin up only light loads and nothing over rpm at the moment The first couple of days with the car showed that although the dualogic gearbox was good, it wasn't particularly smooth.

Upshifts could be a little on the jerky side, a little like a newly qualified driver. Things seem to have changed for the better now, whether its down to the engine or just everything losening up after a few miles, the gearbox is most definitely smoother, upshifts are fairly smooth and down shifts, with the built in throttle blip, are bloody good.

If the gearbox does have a flaw, it is its fuzzy logic, yes it learns your driving style to a degree, but unfortunately it sometimes applies what its learn't at the wrong time.

The latest incarnation of this flaw was after driving through the local forest, nothing to energetic but the road is very twisty with loads of 2nd gear running. After coming out of the forest and onto straighter roads, the car seemed intent on staying in second gear even when we were running at constant speed in 2nd at rpm!!

It was obviously wanting to have some more fun! Still this is only a small problem, and is easily sorted by just flicking the gear selector up a cog. With the dualogic, unlike the Alfa Selespeed system, if you do this the gearbox changes gear but stays in full auto mode. Nice, if like me you are used to a lazy auto box. In the forest I also got to see what the handling was like. For a small car it rides on fairly wide rubber. I'm not sure why they have put such wide tyres on the car, it is not as if it is the sport model, and initial jaunts have shown that the car does follow the camber of the road, and tramline quite alot.

Back in the 90's I had a XS the sporty 1.By Honest John. I bought an ex-showroom Fiat Bravo 1. For 35 years I have always driven automatics and although I took the Fiat on a test drive, it covered mainly country roads and I found no problem with the automatic.

However, when I brought it to London I soon discovered issues with the transmission that I find strange. The main problem is, after slowing down on the approach to a junction or a roundabout, there is a massive flat spot when accelerating, such that I find myself stuck in no-mans land on occasions.

I have asked one of the London Fiat dealers to investigate, but I am told that a computer check shows nothing wrong. The problem is the way you are driving it. It is not an automatic.

Fiat 500 1.2 Dualogic

It is an automated manual. Electronics and an electric motorised clutch change the gears of a manual gearbox for you. But the system seeks to limit torque reactions on upchanges, particularly first to second and second to third when they can be most damaging to the transmission. If you try to compensate for this by stamping on the accelerator it will result in what you describe. You have to be gentler with the accelerator. Basically, anticipate when the box will want to change up.

City cars are normally at their best when best-suited to the stop-start torment of urban traffic. So is the new Fiatrecently showered in glory in not-one-but-two Autocar supermini group tests, even better with two pedals, rather than a five-speed manual gearbox?

Also, are its charms diminished by Fiat's 69bhp 1.

Q: Automatic position in dualogic doesn't work properly

First, a technical distinction. In our test car it developed some extra vibration and harshness on the overrun, but only after a very extended drive. Unfortunately, the 1. Its 75lb ft of torque is marginally more manful than its 69bhp, but neither make this car relaxing or effortless to drive in urban rush hour.

You have to be quick on the throttle to make sure that you don't get left behind at traffic lights, and often have to work the engine hard to keep up with the flow. And as the noisy thrash of pistons once you get about rpm bears testament, that's something that isn't particularly quiet, or pleasant, to have to do. Probably not. If you spend absolutely all of your time in nightmare traffic, or just find the idea of a third pedal too repellent to contemplate, it may be a better option for you than a manual - just.

However, most of us can still do a better job of swapping cogs, and responding to the cut-and-thrust of metropolitan commuting, ourselves than this gearbox can on our behalf. Opting for the 1. At that level, this is a stylish, desirable and cool supermini that's yours for less than the price of the cheapest Citroen C2 - which is none of the above. Don't agree with the quick dismissal of the dualogic. It deserves more detailed examination.

When designing a gearbox with electronic controls, safety is paramount - which is why the brake has to be pressed when initiating drive or changing direction. I know from personal experience that people can be killed if designers get it wrong. In Italy drivers love the Dualogic gearbox.

The only issues I have found are that it can be caught out in slippy conditions. If the wheels spin the clutch will engage fully when you might not want it to, e. I think that this could be overcome with a speed sensor on one of the rear wheels and ECU software to suit. Back off on the accelerator and you get super smooth lazy gearchanges, give it more throttle and you get sportier performance - simples!

I have just started driving my new Fiat Dualogic. I love it, once you get used to depressing the brake pedal each time you need to move from neutral to auto or manual.The DuaLogic transmission is used in some Fiat cars to deliver better performance combined with fuel economy.

The DuaLogic gearbox combines the features of an automatic gearbox with those of a manual gearbox, and uses an onboard computer to aid performance and fuel savings.

The DuaLogic transmission ensures the gearbox is always in the most effective gear for the driving conditions.

The DuaLogic gearbox uses an electrohydraulic servo to automate the clutch and gear lever. In semi-automatic mode, the driver uses a lever rather than a clutch pedal to change gears up or down. The DuaLogic contains a computer, which collects data from the gearbox, the clutch, braking system and the engine. This allows the DuaLogic to coordinate the actions of the gearbox with those of the rest of the car, for example, automatically increasing engine speed when you downshift.

In automatic, the DuaLogic can also recognize road gradient and can change the gear shift point to give the best combination of performance and fuel economy. The DuaLogic has a choice of operating modes for the driver to chose from. In automatic mode, the DuaLogic selects the gears and operates the clutch. In automatic, the DuaLogic's electronic management system will change gears at the time of maximum engine performance to achieve maximum acceleration.

In manual mode, the driver selects the gears and operates the clutch, as in a normal manual transmission. In semi-automatic mode, the DuaLogic operates the gearbox, but the driver can downshift when she feels the need -- such as to take a corner at speed. The DuaLogic computer uses fuzzy logic to adapt to the driver's driving style and road conditions, so it can anticipate when the car will decelerate and downshift accordingly.

This allows the car to be driven in the most fuel efficient manner. The DuaLogic also has several safety features that can make it safer than a manual transmission. For example, it shifts automatically to neutral whenever the engine is running and the door is open, and turns on warning lights and buzzers to alert drivers of maneuvers that could damage the engine or gearbox.

The main disadvantage to the DuaLogic is that, because it is a complicated piece of equipment, and combines electronic and mechanical parts, there is more that can go wrong with it than with a standard manual transmission. Because the DuaLogic incorporates a computer system, it is very difficult to repair it yourself, and repairs may be more expensive than with a purely mechanical manual transmission.

Photo Credits driving position image by Robert Kelly from Fotolia.My car is dualogic and I have chosen to drive it as full automatic. It is also POP. If driving around 30 mph and I brake with medium-harsh pressure for a long time it goes into neutral. The brake still does work, but the accelerator does not work and I can not use it any more.

This causes me to have to come to a hault, anywhere I am. Also, when I need to change between neutral, auto, etc. So annoying! Usually I have to turn the engine a few times before it will work. Do you think this is a safety feature or something else and what can I do to solve this problem? A common component on your particular vehicle that fails is the gearbox communication unit.

When they fail it will cause the transmission to shift into neutral without command. Fiat is assessing this problem and enough people have reported it that a recall should be on the way. Replacing the gearbox communication unit should fix your problem but I recommend having a technician test out the unit first before purchasing any new parts.
