2011 Ford Fiesta Features | Official Site of the Ford Fiesta | FordVehicles.com


PowerShift six-speed automatic provides torque to the wheels 100 percent of the time, for an extra-connected feel. It’s equipped with a leak-free dry clutch technology and a neutral idle mode that helps eliminate drag and contributes to fuel efficiency. It’s also maintenance-free – with a fill-for-life transmission fluid that requires no dipstick – and designed to last up to 150,000 miles.

The 6-speed unit is a dry clutch setup that will go into the Fiesta first when it launches at the end of this year. Ford's first DCT application in Europe is a wet-clutch setup on the diesel Focus.

Compared to existing four speed automatics, the PowerShift will yield a 9 percent improvement in fuel efficiency as well as facilitating extra features. During coast down, both clutches are automatically disengaged, reducing drag. The control of the clutches is also integrated with the brake system to provide hill-hold and launch assist. The dry-clutch PowerShift is 30 lbs lighter than the existing four speed automatic on the U.S. Focus. This gearbox already appeared in the Lincoln Concept C and Volvo S60 concepts in Detroit last week and will make its way into other smaller Fords in the next couple of years.

Overall, Ford has committed that almost 100 percent of its transmissions will be advanced six-speed gearboxes by 2013. Six-speed transmissions already have helped vehicles such as the 2010 Ford Fusion achieve best-in-class fuel economy, while at the same time allowing the Ford Flex and Ford Escape to achieve unsurpassed fuel economy in their respective segments.

Ford is leveraging six-speed transmissions, advanced internal combustion engines such as EcoBoost, hybrids, full electric vehicles, vehicle weight reduction and electric power-assisted steering to improve fuel economy and reduce greenhouse gas emissions fleet-wide by 30 percent by 2020.

Automatic Comfort
Compared to traditional automatic four-speed transmissions, PowerShift can help reduce fuel consumption by up to 9 percent depending on the application.

PowerShift provides the full comfort of an automatic with a more sophisticated driving dynamic, thanks to uninterrupted torque from the dual-clutch technology, which consists essentially of two manual transmissions working in parallel, each with its own independent clutch unit. One clutch carries the uneven gears – 1, 3 and 5 – while the other the even gears – 2, 4 and 6. Subsequent gear changes are coordinated between both clutches as they engage and disengage for a seamless delivery of torque to the wheels.

In Europe, Ford currently offers a PowerShift transmission in the Ford Focus. This PowerShift uses a twin wet-clutch system to handle the higher torque levels of the 2.0-liter TDCI engine available in the Focus.

In North America, a dry-clutch derivative of Ford's PowerShift transmission will be used for added efficiency and durability. A dry clutch transmits power and torque through manual transmission clutch facings, while most automatic transmissions utilize wet clutch plates submerged in oil. As a result, the dry-clutch PowerShift transmission does not require an oil pump or torque converter, providing superior mechanical efficiency.

"A dry clutch is a real sweet spot for lighter vehicle applications," said Piero Aversa, manager, Ford Automatic Transmission Engineering. "PowerShift is more efficient, it saves weight, is more durable, more efficient and the unit is sealed for life, requiring no regular maintenance."

PowerShift, unlike conventional automatic transmissions, does not need the heavier torque converter or planetary gears. In addition, the dry-clutch derivative eliminates the need for the weighty pumps, hydraulic fluids, cooling lines and external coolers that wet clutch transmissions require. As a result, the dry-clutch PowerShift transmission can weigh nearly 30 pounds less than, for example, the four-speed automatic transmission featured on today's Ford Focus.

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.

My wife's 7 speed Mercedes is awesome. Makes the DOHC V6 drive like a powerful V8 and get MPG comparable to many 4 bangers.

I believe the supercar shoot out had the Mitsu Evo beating out all other cars and the author said the drivers just left the car in (sit down) D.

Imagine a 7 speed direct shift high rev Si. Sure it might not be as fast as a Cobalt SS but it would keep up in most performance and offer superior EPA, MPG, and durablity.

Automatic have pretty much been the future here in the US. I hardly think this is revolutionary, check out the new ZF 8speeds. They can be outfitted to turn the host car to a Hybrid, without really doing anything to the car.

It can downshift skipping through 4 speeds reducing lag, and improving response times.

I dont know all the facts off hand, but THAT is a revolutionary auto gearbox.
Porsches PDK system as well, coupled with its new diffs.If that can shave a second from the porsches 0-60, imagine what kind of efficiency that its producing. That will allow smaller and smaller engines to propel our cars. Im just saying

Automatics are the future because people have gotten more and more lazy thats all.

Laziness has become our future. Just hink of this, how many house holds these days use their stives at home to cook homemade meals?

This just expands our choices in cars we can buy if our wives are not able to drive manuals. I know the Audi's with DSG made that possible for me.

I have severe arthritis. Driving manual actually hurts when I'm having a bad day. I prefer a manual but am forced to live with an auto. Once I adjusted , I found it to be not so bad afterall.

I like a good automatic, but like a manual even more. My ideal garage will have at least one automatic vehicle among manual ones.

I think it's a combination of laziness and poor driving skills that are killing the manual. Obviously, many people don't want to put forth the extra physical effort to drive a stick. Also the high rate of clutch & syncro problems in enthusiast cars due to many inexperienced & under skilled drivers attempting to show off their "skills" are leading people away from the three pedal setup into a modern automatic or dual-clutch gearbox.

No chance of miss-shifting or burning a clutch when the computer does it all for you. The dual personality of many modern gearboxes appeal to the older demographic that would rather just sit back and cruise most of the time, yet still have that option for a full-on, quick shifting manual mode that makes them look like a driving hero.

That'd be a great thread title 30 years ago... admittedly there wouldn't have been a 2ndcivic.com to post it on though ;-)
AT's have ruled the roost in North America for as long as most of us have been driving. Regardless of whether Ford has this "powershift" setup, they're going to be selling a ton of automatic Fiestas.

IMO, I see dual-clutch transmission a great benefactor for drag racing. But, I
don't see manual transmission disappearing in the future...

If that so, then the " future " is boring.

Also I agree with what taffy07si said. Peoples are getting lazier (if this is how it suppose to spell) these days and want the computer to do most of the jobs for them.
