FoFi 6speed dual clutch gearbox by Getrag 6DCT250 Infomation for sharing.This gearbox also applied in Renault Magane.

–Newly developed dual clutch transmission with dry clutch starts on the NAFTA market and in Europe
–Reduction in fuel consumption up to 20 percent

– Common-part strategy allows versatile applications in small and medium sized vehicle segments and reduces manufacturing cost

UNTERGRUPPENBACH, Germany, IRAPUATO, Mexico, and MODUGNO, Italy, April 16 /CHICAGOPRESSRELEASE.COM/ — At the Getrag plants Modugno / Bari und Irapuato, the serial production of the youngest member of the Getrag Powershift family has commenced. The 6DCT250 transmission will first be introduced in the Renault Megane and the Renault Scenic and for the NAFTA market in the Ford Fiesta. For 2010, quantities of over 100,000 transmissions are planned already, which will increase to over 400,000 annually by the end of 2011. The 6DCT250 was developed for integration in small and medium sized cars.

“Modugno plays a key role regarding manufacturing of highly modern transmission technology” says Bernd Eckl, COO of the Getrag Group. The Modugno plant is responsible for the complete manufacturing of the gear sets for Europe and the assembly plant in Mexico and additionally assembles transmissions for the European market. The Italian Getrag plant was redesigned and restructured for the new dual clutch technology and will be running at full capacity by 2012. The newly built Getrag location in Irapuato is responsible for the assembly, end of line control and delivery of the transmissions produced for Ford and was designed optimally for this task.

The consistent common-part-strategy allows a fast and cost efficient adaption to customer needs. Further, all variants can be realized with only one production line type. “With the Getrag Powershift 6DCT250 we will usher in the second era of dual clutch transmissions,” says Eckl. The transmission makes further reductions in fuel consumption of up to 20 percent possible compared to a conventional torque converter automatic transmission. “Due to the dry dual clutch and the electromechanical actuation, the transmission surpasses even the conventional manual transmission in fuel consumption and CO2 emission” explains Eckl. The 6DCT250 is very versatile in its application. A start-stop functionality can be installed without any modification or extension of hardware. The transmission can be combined with an all-wheel drive power train and, when coupled with an e-motor, can be applied as hybrid solution. Overall driving pleasure and enjoyments are also not neglected: Getrag consistently built on the experiences of the already introduced wet dual clutch transmissions. “The transmission receives great interest worldwide, as it perfectly satisfies the market requirements of today and the near future. We already are in talks with several additional OEMs” says Eckl.

For more detail ,pls read this:

Differentiating PowerShift even further in terms of its customer appeal is its shift quality, launch feel and overall drive dynamic, which are all facilitated by an expert blend of Ford-exclusive electro-mechanical systems, software features, calibrations and controls. These unique driving features include:

•Neutral coast down – The clutches will disengage when the brakes are applied, improving coasting downshifts and clutch robustness as well as reducing parasitic losses for increased fuel economy.

•Precise clutch control in the form of a clutch slip to provide torsional damping of the engine vibration – This function improves noise, vibration and harshness (NVH) at low engine speeds and enables lower lugging limits for improved fuel economy.

•Low-speed driving or creep mode with integrated brake pressure – This function simulates the low-speed control drivers are accustomed to from an automatic transmission. The amount of rolling torque in Drive and Reverse is precisely controlled, gradually building as brake pressure is released.

•Hill mode or launch assist – Prevents a vehicle from rolling back on a grade by maintaining brake pressure until the engine delivers enough torque to move the vehicle up the hill, providing improved driver confidence, comfort, safety and clutch robustness


-A dual clutch transmission can almost be thought of as two traditional manual transmissions, each with its own clutch operating in parallel and alternating shifts. The Ford unit is a six-speed with one clutch acting on gears 1, 3 and 5 and the other used for 2, 4 and 6. As first gear is engaged, the 2-4-6 clutch is disengaged and the second gear cogs are engaged. At the appropriate time, the 1-3-5 clutch is disengaged the other is engaged. While in second gear, the other side moves from first to third. The process is repeated with quick smooth shifts and none of the of the efficiency loss normally associated with torque converters.

The Pwrshift Transmission is adaptive in nature?
I find that the gear shift are now at a lower rpm.
iS IT ADAPTING TO MY DRIVING STYLE?

yes, it can.
Try this.
As you approach the corner, induce a downshift by blipping the throttle.
then throttle through the corner.
Fun....

let say i driving at 130kmh, but then i wan to downshift the gear to 2nd gear before enter the corner and maintain 2nd gear until i going over the apex and full throttle again...

possible to do that?

Maintaining the gear position can be achieved by setting OD on and some throttle control. Downshifting is a bit tricky i think, first off you dont really know when it's gonna downshift, secondly which gear is it in currently. It is possible but tricky.

Something slightly off topic here about the company that produces our gearbox Getrag ...

Dongfeng Motor Group is said to be in talks to acquire a 30% stake in German auto parts supplier Getrag, one of the world’s biggest manufacturers of transmissions. Both the dry clutch used in all Ford Fiestas and wet dual clutch transmissions found in other Volvo cars in Malaysia are supplied by Getrag. The Chinese companies usually source engines, transmissions, and even platforms from other more established car companies & then later piece them together but with their names on it. Maybe this is not such a bad idea as long as they don't produce their own fakes/imitations Smile

30% hardly gonna do anything.

On other news (or rumors), I heard proton gonna get getrag as their standard transmission for future models. The first model gonna receive the 6 speed manual (i think the same one as ours) is the persona replacement model, that's gonna be launch either 4th quarter 2011 or early next year.

True or not we will see.

Can imagine them getting a stake, learn up the technology and then come up with a Made-in-China gearbox called GeRTag (not Getrag).

Quoted:

"The Powershift is the same gearbox first introduced locally in the Ford Focus diesel, and similar to the 'DSG' unit found in the impressive rival Volkswagen Polo, but with one fundamental difference - Ford's works better in traffic.

While the DSG's indecisiveness and lag in stop-start traffic can be annoying - and potentially dangerous in some situations - the Fiesta's transmission is a very different beast.
"

Hmm....so Powershift is better than DSG. Is the jerkiness we feel is a common trait among direct shift, dry-clutch transmission?

I tried searching for volvo's powershift but unfortunately cant find any new info. Mostly on things already mentioned on ford's fiesta/focus review.

Hi all i dunno where to post this. Driving styles and tricks.

Mostly from my experience, i'm a bit dissapointed with how the gearbox reacts to our throttle input.

While overtaking a car, i noticed that once i brake, i got the rpm reduced and theres a 1 second lag before i get the boost once i floored the pedal. Is it due to the clutches playing their roles?

Im a careful person when driving but let say if i need to go faster to avoid dying faster when overtaking? Any tricks to get the boost instantly without feeling too much lag?

I drove a myvi and a city ocationally, and they are very assuring in terms of giving the power to overtake. This assurance is absent in fiesta, using my driving style. Any advice?

Btw i tried using the od button like suggested by our bro/sis carbonara (sorry. Never been to a TT). Still the lag. But better in getting more boost. What i am asking is any trick to induce the downshift without the lag while overtaking

My advice. Dun follow up an overtaking car. If he brakes, u ll be in problem, if ur pedal flooring style is same as mine.
