DPS6 – Key Benefits
Improved fuel economy

Very high mechanical efficiency vs hydraulic A/Ts.
 Eliminates the need for hydraulic controls
 No torque converter, no oil pump… no parasitic losses.
 Low viscosity transmission oil



6 speed wide ratio span (5.58) allows the engine to run
at optimal operating speed for both city and highway.
Powertrain control innovations to maximize efficiency
Maintenance Free
 Fill for life trans oil - No dipstick checking required
 Dual clutch is designed to last for 10 years / 150k miles
 Cooler lines are eliminated, no oil leaks

Transmission Controls Innovations
Ford Controls and Software Development Engineers have developed novel
control strategies to maximize customer satisfaction with the Powershift
transmission:
• Neutral Idle – the clutches will disengage when the brakes are applied.
This function Increases fuel economy, improves coasting downshifts and
improves clutch robustness.
• Precise Clutch Control – Micro Slip for NVH Improvements
Provides torsional damping through clutch slip. Improves NVH at low
engine speeds and enables lower lugging limit for improved fuel
economy.
• Torque Hole Filling – Provides smooth torque transfer during up shifts
through precise coordination of engine torque delivery during the shift.
• Tip In/Back Out Logic – All new algorithms developed to provide smooth
torque transitions to handle rapid changes of driver pedal input.
Transmission Controls Innovations
• Slow Speed Driving (Creep) w/ Integrated Brake Pressure – Provides
typical creep function that drivers expect out of an automatic
transmission (torque as a function of brake pressure). Provides
customer comfort and control for low speed/parking lot drivability.
• Hill Mode – Launch Assist – Integration of the brake control function with
the transmission strategy to provide improved drivability on hills. Brakes
will hold brake pressure until the engine delivers enough torque to move
the car up the hill. This feature prevents vehicle roll back on a grade.
This provides improved driving confidence/comfort/safety while also
providing clutch robustness.
• Ford Grade Assist – Implementation of Ford Grade Assist algorithm for
improved driveability/control on hilly terrain. Driver selectable function
through button on shifter.
DPS6 Transmission – key points
- All NEW, segment exclusive DCT technology.
– Enables Fiesta to achieve outstanding fuel
economy.
– Provides the connected feel of a manual
transmission, while also providing smooth gear
shifts and the convenience of conventional
automatic transmission.
– Delivers new functionality to the customer
through the use of electro-mechanical control
systems and Ford developed controls
innovations.
