“With all-new powertrains and increased capability, the 2011 Super Duty improves on its proud heritage as the ultimate work truck.” [fflash=left]http://www.youtube.com/v/USUs26cv7tY&hl=en&fs=1[/fflash]Wayne Gerdes - CleanMPG - Sept. 24, 2009 Meet the 2011 Ford SuperDuty. When choosing a work truck, commercial and fleet operators demand the best. The all-new 2011 Ford F-Series Super Duty is designed and built to deliver with improved torque and horsepower plus class-leading fuel economy. “Having the most capability means a customer doesn’t have to marginalize any segment while he tries to maintain and build his business,” said Jim Michon, truck fleet marketing manager. “Our customers expect the leadership capability that our trucks deliver and, with the 2011 Super Duty, they’ll also gain a significant improvement in fuel economy. It’s a win-win situation for commercial and fleet owners.” Ford SuperDuty - Lowering the cost of ownership The new 6.7-liter Power Stroke V-8 turbocharged diesel will deliver significantly improved fuel economy while also maintaining Super Duty’s best-in-class towing and payload. The architecture of both engines has been optimized for efficiency, as has the new TorqShift heavy-duty six-speed transmission. The transmission’s fluid change interval also has been extended, in part due to a dual filter that provides fine filtration and large capacity in a single package. The dual filter also eliminates the need for a spin-on external filter. The new 6.7-liter diesel’s architecture reduces down time during service work, which helps get vehicles back on the road faster. Service time on the EGR (exhaust gas recirculation) cooler and high-pressure fuel pump is expected to be markedly reduced because of the new layout. The new spin-on oil filter makes that servicing easier as well. The new Power Stroke, featuring Tow Haul Mode with the integrated engine exhaust brake, helps improve driver confidence with large loads and prolong brake pad life. Drivetrain We previously covered the all-new Ford designed and built 6.7L diesel for the 2011 SuperDuty plus had a sit down in the revealing Q&A with Ford’s Adam Gryglak - Large Diesel Engine Engineering Program. What has yet to be described was how Ford was going to transmit the PowerStroke’s power to the wheels. All-new 6-speed automatic transmission w/ 2 OD gears Managing the increased horsepower and torque is the all-new 6R140 heavy-duty six-speed transmission, which delivers power quickly and seamlessly while maximizing fuel economy. “Our new transmission perfectly complements our new diesel and gasoline engines to give the customer the best powertrain for Super Duty applications,” said Al Bruck, 6R140 transmission engineering manager. “Rigorous testing ensures our transmission and powertrain is up to the challenge of even our most demanding Super Duty customers. Overall, the 6R140 heavy-duty TorqShift six-speed transmission enables greater customer capability, efficiency and control than ever before.” Lepelletier powerflow: New diesel application of tried-and-true system Ford’s 6R140 TorqShift transmission uses a Lepelletier-style powerflow, which is a proven technology in rear-wheel-drive vehicles but not typically used with larger diesel engines. A key benefit of the Lepelletier architecture is that it reduces the complexity in connecting the gearsets and clutches. The six speeds require only five clutches, and the speeds of the clutches relative to one another are low, increasing the efficiency of the system. To handle the torque of the 6.7L PowerStroke, Ford strengthened the system by employing a unique powder-metal carrier in the compound Ravigneaux planetary gearset. The carrier consists of four pressed powder-metal components sinter-brazed together to form a rigid, power-dense structure. This solution ensures robustness and makes the architecture compatible with both the diesel and gasoline engines. A Ford-patented rocker one-way clutch is integrated with the carrier and helps improve 1-2 shift quality through the gearset. “With this architecture, the new transmission can handle the enormous low-end torque produced by the new diesel engine as well as the high speeds produced by the new gas engine,” Bruck said. “The sinter-brazed gearset enables more torque capacity and greater engine speed capability.” A deep first gear ratio and two overdrive gears create a wider ratio span. This, combined with available lower axle gear ratios and a control system that automatically selects the most efficient shift schedule, provides an outstanding combination of pulling power and fuel economy. “Because we have six gears, we make smaller steps gear to gear, which helps keep the engine in its sweet spot in terms of performance and efficiency.” Six-speed gearbox – automatic or manual operation The 6R140’s heavy-duty TorqShift six-speed transmission balances convenience and control by automatically shifting during routine operation and also allowing complete manual control. It features SelectShift Automatic transmission functionality, which includes both Progressive Range Select and manual functions. With Progressive Range Select, a toggle on the shift lever allows the customer to reduce the range of available gears while in Drive. When the customer “taps” down into Range Select mode, the display shows the available gears and highlights the current gear state. This feature allows the driver to limit use of upper gears when heavily loaded or while towing on grades. For full manual function, customers also can pull the shift lever into “M” for manual mode and use the same toggle switch to select the gear desired. The display will show the selected gear, and the control system will lock the torque converter and hold that gear for a full manual transmission feel. Torque converter - The torque converter of the 6R140 transmission is designed to be accurately controlled and efficient. A closed-piston design provides precise control of the lock-up clutch. Its torque multiplication is matched with the rest of the powertrain for better off-the-line performance, but that’s only the start. Once under way, a long-travel, high-capacity turbine damper allows the torque converter to dampen out the extreme torsional force produced in particular by the new, more powerful diesel engine. “This damper allows us to lug down to 900 rpm while our competitors lug to around 1,100 rpm,” Bruck said. “This technology allows us to stay locked more, which means the engine can run at a lower rpm and get better fuel economy.” New-to-segment Live Drive PTO (Power Take Off) – adds functional improvements. On the 2011 Super Duty diesels with the PTO prep option, the PTO output gear is linked through the torque converter to the engine crankshaft. This allows the transmission to power auxiliary equipment such as snowplows, aerial lifts, tow truck lifts, cement mixers or dump trucks. The power is available any time the engine is running. Technology to help your business As we first experienced in the 2010 Ford Transit Connect Preview, the Ford SuperDuty delivers improved telemetic, utility and “Work Solutions”. Available Ford Work Solutions is one of many technologies that can help owners manage their business from the work site. Ford Work Solutions delivers four innovative features: An in-dash computer developed with Magneti Marelli and powered by Microsoft Auto that provides full high-speed Internet access via Sprint Mobile Broadband Network and navigation by Garmin. This system allows customers to print invoices, check inventories and access documents stored on their home or office computer networks on the job site as well as navigating to the next. Tool Link™, a Radio-Frequency Identification (RFID) asset tracking system developed in association with DEWALT, the industry leader in professional power tools, and ThingMagic, the industry expert on embedded RFID technology. This enables customers to maintain a detailed real-time inventory of tools or equipment stored in the pickup box. Crew Chief™, a fleet telematics and diagnostics system, which allows small fleet owners to efficiently manage their vehicles, quickly dispatch workers to job sites and keep detailed vehicle maintenance records.
