As we reported on Autoline Daily, Ford has developed a new kind of front suspension that eliminates torque steer. Called RevoKnuckle, it looks. Ford’s RevoKnuckle front suspension is a re-engineered version of the McPherson setup which weighs less and costs less than a double. NASICS: RevoKnuckle suspension. 5th July hen Ford were developing the Mk2 Focus RS they had a problem to overcome. Big power (bhp), and.

This is the future, today. Used Ford Focus 7, cars.

Search My Stuff What’s New 3 12 24 Anyone that’s done any significant performance work on a MacPherson-strut AWD car knows just how important – and difficult – these adjustments are to achieve. BigMansZetec 1, posts months.

Take Us With You! Various innovations, developed as a result of customer feedback from previous performance Fords, have allowed engineers to keep the new Focus RS as front-wheel drive, with a limited-slip differential, while still achieving demanding targets for traction, handling and steering.

PH – Shed of the Year. They know a thing or two about making a FWD car fast, is why, and they thought they could come out with a car that performs better than an AWD equivalent. PH – Reader’s Car of the Year. Stock photography by izmostock. Used Hyundai Elantra 23, cars.

In Depth: Ford’s RevoKnuckle Suspension And Quaife LSD For The Focus RS

Read our Cookie Policy. Cutting out the center differential and rear drive mechanism saves cost, complexity and weight – all enemies of high-performance and affordable hatchbacks.

Torque steer occurs during hard acceleration, cornering or driving on uneven surfaces, when torque on the driven wheels exceeds grips levels. Terms and Conditions Posting Rules. McLaren shows off Speedtail design themes so no two cars look alike. For the limited-slip diff, they called on Quaife, a standard in the field, while they tapped their own engineers for the design of the RevoKnuckle suspension.


Sometimes this involves locking the wheels to spin at the same rate, and in others, it biases torque to the wheel with the most grip.

Our work has shown clearly that our approach in combining a tuned RevoKnuckle with the Quaife differential is an ideal solution for a high performance front-wheel-drive road car like Focus RS. But unlike an open differential, when one wheel starts to spin at a much higher rate than the other, it steps in to keep the spin from revokjuckle into futile burnt rubber.

Lidar, big data could make de-icing roads more efficient.

So in the end, Ford thinks it has come out with a product that will beat the competition thanks to a lighter, more tactile solution that offers a better combination of power, traction and driving dynamics. To separate emails with commas. To overcome the torque steer issue, the engineers used a standard MacPherson strut architecture, but added a two-piece knuckle that adds a ‘C’ shape to the lower revoknudkle mount. The mid-size pickup truck pace-setter. But yeah, it would be interesting to know. Forum

Thanks Dave, that has shed light on the subject. Spy Shots December 31, Ive read the story on the new Rs and was just wondering if anyone on here can shed some more light on this ‘new’ design have searched the net and found nothing. Alfa Romeo Stelvio Quadrifoglio. Latest Features British Columbia: I can withdraw my consent at any time by unsubscribing. It allows the simplicity of a traditional McPherson strut arrangement, but with geometry settings that minimize steering disturbances and torque steer, principally a reduction in steering offset.


Like all limited-slip differentials LSDsthe Quaife unit allows some degree of freedom of rotation between the two drive wheels—that’s what makes it possible to turn corners smoothly.

Latest News British Columbia: Used Volkswagen Golf 2, cars. Was hoping to see a picture or diagram, as i want to know how it works as opposed to revoknucckle it does.

As one wheel slips, it spins faster, and the torque differential across the two forrd of gears increases, progressively locking the set that’s transferring the most torque, slowing its speed and sending more power to the wheel with more grip. A side benefit of the RevoKnuckle system is improved traction in addition to minimized torque steer thanks to greater freedom in configuring camber, caster and trail.

Get the Web’s best daily performance and luxury automotive newsletter! It is characterised by fevoknuckle turning force on the steering wheel and can be exacerbated by vehicles with wide tyres and limited-slip differentials. News Chevrolet Corvette preview Sports Cars an hour ago.
