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.

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 degenerating into futile burnt rubber.

One downside of the helical LSD, or any torque-biasing unit for that matter, is that if one wheel becomes unweighted or otherwise completely loses traction, the differential won’t function – it becomes in essence an open differential.

Thanks Dave, that has shed light on the subject. McLaren shows off Speedtail design themes so no two cars look alike. Alfa Romeo Stelvio Quadrifoglio.

How it accomplishes this task is what regoknuckle the type of differential, and there are many ways, including helical, clutch-type and viscous coupling LSDs.


Various innovations, developed as a result of customer feedback from previous performance Fords, have allowed gevoknuckle 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. Instead they focused on making the front differential and suspension the best possible.


PH – Shed of the Year. As one wheel slips, it spins faster, and the torque differential across revokjuckle two sets 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. It is a simple, highly robust solution that is also exceptionally effective. Used Hyundai Elantra 23, cars. Most Popular This Week. 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 suspension mount.

The upside is that it sends more power to the grippiest wheel, rather than simply locking them together and potentially losing even more traction, and they don’t revoknucklw to grab and yank the drive wheels, making revkknuckle particularly well-suited to an FWD application.

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. The mid-size pickup truck pace-setter. PH – Reader’s Car of the Year. We’ll email you the latest in performance and luxury automotive news every day.

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.

Used Honda Civic 9, cars. 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.

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.

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. If is so revolutionary, then chances are Ford won’t want to tell everyone how it works. 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.
