GKN supplies innovative AWD system to Ford Focus RS

Recommended Posts


 

GKN Automotive, the world leader in powertrain technologies, has developed a new version of its twin Ster torque vectoring all-wheel system for the Ford Focus RS. The combination of translation offset and innovative control algorithms provides improved torque vectoring functionality and helped Ford to develop a vehicle with outstanding driving dynamics performance. 

 

The specially developed for the Ford Focus RS Twin Ster technology will be presented at the booth of GKN (H 5.1, B32) at the IAA Frankfurt. 

 

Peter Moelgg, President Engineering of GKN Automotive, commented: "The all-wheel technology and the Torque Vectoring expertise of GKN help vehicle manufacturers in the process of opening up new areas with their models. Especially for vehicles with high performance is the intelligent all-wheel drive to the drive technology par excellence; it is the most effective way the power, precision to bring, efficiently and intelligently to the road. " 

 

GKN was awarded the contract for the Ford Focus RS program only 18 months before the launch. During this time the engineers at GKN the rear axle torque vectoring (RDM) and the Power Transfer Unit (PTU) and the CVJ side shafts have developed and integrated into the front-wheel drive-based platform. To the system in the existing space to "packagen", a deep feature integration of the system components required. The GKN software and calibration teams have jointly developed with Ford vehicle dynamics engineers new control algorithms for the Torque Vectoring system to provide such a drive train with four different driving modes can. 

 

Dr. Ray Kuczera, GKN Driveline Vice President Global Product Technology, said: "GKN is the only manufacturer with the know-how and the ability to deliver these different hardware and provide the vehicle by integrating software and performance calibrations. To provide torque vectoring systems of this quality, it requires engineers to understand the dynamics and have the ability to work together with car manufacturers on vehicle level. The result of this partnership with Ford shows how powertrain innovations affect the driving dynamics and can heave the handling performance to new levels. "

How the system works by GKN

When Ford Focus RS a wheel system GKN with PTU and a rear axle with twin Ster-coupling system is used. GKN's Twin Ster technology can distribute wheel-selective torque to the wheels. This allows dynamic torque vectoring capabilities of the vehicle over the entire speed range. 

 

The latest version of the Twin Ster-system in the Focus RS detected driving situation and driver demand and regulates this optimal torque distribution to each wheel. If the wheel drive is activated, Twin Ster drives the rear wheels faster than the front wheels. 

 

This effect changes the driving characteristics and handling fundamentally. In curves the twin Ster technology allows more agile oversteering and a direct response to the driver's commands. In Ford "Drift mode" distributes the wheel drive system even more torque to the rear axle in order to settle so enough power to the wheels of the RS and to allow a controlled drift through corners. 

 

Other "Torque Vectoring systems" use the brake system for simple vectoring effects, however, which lead to a deceleration of the vehicle. A fully dynamic torque vectoring requires an intelligent drive system, which can transmit the driving wheel-selective moments. Significantly Improve Performance and pure driving pleasure with reduced braking intervention are the result. 

 

Edward Kwon, Senior Director GKN Driveline AWD Product Technology, finally said, "all-wheel models like the Ford Focus RS write the rules for new drive systems - and innovation at GKN assist in their implementation. Our expertise in dynamic torque vectoring helps his model and to set new performance standards.

Very cool technology, I can see a day when all auto's will come AWD in all levels as more and more people will see the safety benefits of having an AWD system.

Hmmm, since I can't seem to post a new thread as a guest on this computer, I will just leave this RS news right here.  Seems topical enough.

 

=====================

FRANKFURT, Germany,  –  Ford Motor Company has announced that the all-new Focus RS will sprint from 0-62mph in 4.7 seconds, making the high-performance hatchback the fastest accelerating RS model ever.

The Focus RS will reach a top speed of 165mph powered by a specially engineered version of Ford’s new 2.3-litre EcoBoost engine delivering maximum power output of 350PS.

Ford also announced that the Focus RS is now available to order with prices from £28,940.

The all-new Focus RS optimises acceleration by introducing Launch Control technology to a Ford RS model for the first time. The model also debuts new Ford Performance All-Wheel Drive with Dynamic Torque Vectoring, for outstanding traction and grip with unmatched agility and cornering speed.

The Focus RS is joined on display in Frankfurt by the full Ford Performance line-up for Europe, including the all-new Ford GT ultra-high-performance supercar, Focus ST wagon and 5-door models, and the multi-award-winning Fiesta ST.

=====================================

 

 

Pretty good numbers. I could live with this 4 door hatchback, with all season AWD all year long.  Hard to do all that with a Mustang.  I bet this offers even more fun as well.

Might as well leave this video here as well, which leans heavy on the 'fluff' but does show the RS in action.

Seems at 2:40 is where the AWD - Awesome Wickedly Drifting starts according to their own text.

 

 

Seems pretty cool, wonder how long before this is shown on an all electric version. :D

Weird how Baby Powder Blue is making a comeback in car color.
