riguardo ai modelli PHEV, BEV, compagnia bella

Credo che qualcosa di concreto sarà presente al Naias e penso che qualcuno provvederà domani ad aprire una discussione ad hoc in seconda battuta.

Comunque questo è il calendario, probabile, di lancio dei modelli Ford con tale tecnologia:

2010 in inghilterra due veicoli commerciale elettrici ,Transit e connect, con la collaborazione della Tanfield.

2011 modelli sulla nuove piattaforme globali C e CD in collaborazione con MAGNA.Prima in nord america e poi europa e asia (vedi immagini sopra)

Press release:

ford to introduce fuel-efficient dual-clutch powershift transmission in north america in 2010

detroit, jan. 21, 2009 – ford motor company announced today it will introduce an advanced dual-clutch powershift six-speed transmission in north america in 2010 for the small-car segment.

Powershift will deliver the fuel efficiency of a manual gearbox with the convenience and ease of a premium automatic transmission – making it a key enabling technology as ford targets best-in-class or among-the-best fuel economy with every new vehicle it introduces in north america.

"powershift represents a true competitive advantage for ford and is one of the many technologies that will help our global small-car platforms set a new world standard for efficiency and drive quality," said barb samardzich, vice president, global powertrain engineering, who announced powershift's production timing at the 2009 automotive news world congress. "this advanced six-speed is an improvement over today's automatic transmissions in terms of fuel economy, while providing customers an even more fun-to-drive experience."

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.

BEEFED-UP SIX-SPEED TRANSMISSION MEETS HIGH-TORQUE DEMANDS OF 3.5-LITER ECOBOOST ENGINE

DEARBORN, Mich., Feb. 18, 2009 – Ford's 3.5-liter EcoBoost V-6 engine debuts this spring with the perfect running mate for maximum performance and fuel efficiency – a six-speed SelectShift automatic transmission that's specifically designed for the higher torque demands of the all-new twin-turbocharged, direct injection engine.

Developed from the successful 6F-50 transmission, the 6F-55 is dedicated solely to the 3.5-liter EcoBoost engine and incorporates a number of component and calibration upgrades that help guarantee every drop of torque produced by the turbocharged V-6 is seamlessly transmitted, giving customers that V-8-like performance they love, as well as the fuel economy they demand.

"Adapting the 6F architecture to the EcoBoost engine demanded a close look at every component, piece of hardware, and calibration measure to ensure that this transmission could answer the needs of a higher output engine; help, not hinder, fuel economy; and meet Ford's strict durability standards," said Barb Samardzich, vice president, Global Powertrain Engineering.

The engine/transmission combination is already proving its muster. The 2010 Lincoln MKS, the first Ford Motor Company vehicle to offer the 3.5-liter EcoBoost engine and 6F-55 transmission package, will deliver an impressive 355 horsepower and a responsive 350 ft.-lbs. of torque, along with achieving 25 mpg on the highway.

That's more power and better highway fuel economy than the V-8 engine found in the 2009 Lexus GS460 (24 mpg) or the 2009 Inifiniti M45 (21 mpg). The recently announced return of the 2010 Ford Taurus SHO also will sport the EcoBoost V-6 and the six-speed SelectShift transmission, delivering an estimated 365 horsepower at 5,500 rpm and 350 ft.-lbs. of torque at 3,500 rpm, while maintaining fuel economy ratings on par with a V-6 engine.

Other 2010 products set to offer this powertrain combination include the Ford Flex and Lincoln MKT.

High Torque Edits

The 3.5-liter EcoBoost engine strategically uses two small turbochargers, which are quick to respond to throttle inputs, spooling up instantly for torque output that's impressive – peaking earlier in the rev range than a comparable, normally aspirated engine. The turbo system does, however, run at higher temperatures.

In order to handle the elevated operating temperatures associated with a turbocharged engine and carry the higher torque produced by the 3.5-liter EcoBoost V-6, the 6F-55 incorporates a blend of hardware, material and calibration upgrades.

The transmission features, for example, wider, thicker transfer and final drive gears, improved input and output carriers, and a new differential case to carry the higher energy produced by the engine and deliver the performance customers expect when they accelerate. The ring gear on the 6F-55, for instance, is a beefier 41.5 mm versus 31.5 mm on the 6F-50.

Final drive ratios have been adjusted and matched to gear ratios to provide optimum performance and fuel economy. Clutches also have been upgraded with high-energy friction materials that can handle higher loads and shift energies over the long term. In addition, clutch piston material upgrades can withstand higher operating temperatures. This, along with thicker thrust washers, and an improved heat treatment on the turbine shaft help handle the higher engine torque.

"We had to bulk up and strengthen all of the transmission's core parts for higher duty cycles," said David Capoccia, transmission system manager, Ford Powertrain Operations. "The thicker gears, the improved carriers, upgraded clutches are all part of a set of hardware actions that translate to superior performance and durability for the customer."

The 6F-55's torque converter was also tweaked to improve drivability and create a more connected feel for customers. The converter even has its own exclusive efficiency curve and design for increased strength and durability, bolstered by four lugs welded on the cover in comparison to three on the 6F-50.

A second roll restrictor boss, which limits powertrain movement during acceleration, was also added to the Lincoln MKS and MKT EcoBoost transmission packages for superior noise, vibration and harshness (NVH) and a smooth, seamless acceleration experience.

Fuel Economy Factors

The 6F-55 may be bigger and stronger, but it is not less efficient, according to Capoccia. Several of the transmission upgrades actually help improve fuel efficiency. They include:

* Friction material grooves, which break up the fluid flow between the friction and separator plates and help pump fluid through the plates, have been optimized to reduce overall clutch drag losses.

* Moving from a six to a nine wave CBLR (Clutch Brake Low Reverse) spring – which aids in mechanically separating the clutch plates – provides a flow path for the fluid that reduces overall clutch drag losses.

* Calibration measures, such as reducing the modulated slip from 40 rpm to 20 rpm allows less fuel to be burned to deliver the same torque to the wheels; and locking up the torque converter in lower gears to expand the operating range and provide optimum fuel efficiency.

* Increasing the start-to-open temperature of the bypass valve by 15 degrees, which allows the transmission to run at higher, more efficient temperatures and save fuel.

A High-Volume Commitment

The addition of the 6F-55 builds on the reputation of Ford's 6F transmission architecture.

And like the 6F-50, the 6F-55 offers customers all the benefits associated with an advanced six-speed gearbox, including superior shift quality, improved acceleration, a more refined driving experience and improved fuel economy. In addition, the SelectShift feature allows the customer to choose gears for a more spirited drive.

"The 6F-55 has all the same features that customers have told us they desire from the 6F-50 transmission, and that includes fluid-fill for life and flat tow capability," adds Bryce Bollwahn, a systems supervisor at Ford's Automatic Transmission New Product Center.

Going forward, advanced six-speed transmissions, along with EcoBoost engine technology, will continue to dominate Ford's sustainability strategy. By the end of 2012, nearly 100 percent of Ford's North American transmissions will be advanced six-speed gearboxes. By 2013, more than 90 percent of Ford's North American vehicle lineup will offer EcoBoost technology..

ora sappiamo, con sicurezza, che in primi Test partiranno alla fine dell'anno sul pick-up F 50. Il tutto pare avere tempi biblici, se non incontrerà difficoltà una data ,probabile, è il 2016.

Gira pure al banco un V6 3.5 ecoboost con tale tecnologia

--Ethanol boosting also promises 5 to 10 percent greater fuel economy than Ford’s new line of gasoline-turbocharged direct-injection EcoBoost engines, which it’s based on. Ford’s DOE presentation says, “The E85 optimized engine and the dual fuel concept are logical extensions of Ford’s ‘EcoBoost’ strategy.”--

Quello mostrato in 3D è il già citato 5.0 litri , ora sappiamo che è munito di doppio turbo e di intecooler di notevole volume..
