Power generated by the rear inside wheel is directed to the
rear outside wheel, allowing the handling benefits with little draw from the battery.
During fast cornering, the system boosts the stabilization of the
front outside wheel, for example.
TORQUE VECTORING If you get your 2017 Range Rover Sport with a V8 engine, you also get a unique torque - vectoring setup that provides more power to the rear
outside wheel when turning.
That power can then be forced to a loaded
outside wheel by the brake - actuated torque vectoring system, which can help counteract any understeer.
The Continental GT is also fitted with a brake - vectoring setup pioneered on the outgoing GT3 - R and Supersports models that can move torque from inside to
outside wheels depending on the grip conditions it senses.
Cornering at speed, the valves increase oil flow in the shock at the
deflected outside wheel almost immediately, keeping the body virtually flat.
During fast cornering, the system boosts the stabilisation of the
front outside wheel, for example.
Ford attributes this in part to a standard torque - vectoring feature that uses the traction control to brake the inside wheel when accelerating out of a turn, allowing the power to drive
the outside wheel and maintain a tighter line.
If the prelude is an SH, it might have ATTS, which is basically an active differential directing additional (up to 20 % if I remember correctly) torque to
the outside wheel when turning.
Additionally, an optional sport rear differential can send power to
the outside wheel in a curve.
A quicker steering ratio means the Vanquish feels more alert, while the wheel weights up beautifully as you load up
the outside wheel.
Add throttle in a corner, and the speed - sensing rear differential will suddenly shift grunt to
the outside wheel, inducing snap oversteer.
The performance pack also adds bigger brakes and a limited - slip front differential, so as we toss the GTI into corners, we readily feel the additional torque being directed to
the outside wheels by the trick diff.
Nissan split the rear wing left to right to offer different levels of downforce for the inside or
outside wheel.
The electronic super brain diverts more torque to
the outside wheels than the inner wheels in the way into a corner, and actually applies negative torque — effectively a braking input — to the inside rear.
Instead, it feels heavy when driven quickly as the body slowly rolls onto
the outside wheels.
When you turn to the left, there is a weight transfer to
the outside wheel (right wheel) and any noises from it will be more accentuated / louder.
Also included on all UK cars is the Sport rear differential, which can shuffle power across the axle and, in extreme situations, overdrive
the outside wheel for a more rear - wheel drive feel.m the kerbweight.
A limited - slip differential is integrated into the transmission, and the front motors can either power the car independently or send extra power to
the outside wheel when cornering for torque - vectoring capability.
Pitch the car into a medium speed or fast bend and it snaps sharply into the corner without a trace of understeer, then leans onto
its outside wheels in a very tautly controlled way.
Volvo also uses a rudimentary torque - vectoring system at the rear axle to send more torque to
the outside wheel in corners.
As you toss the GTI into corners, you readily feel the additional torque that's being directed to
the outside wheels by the limited - slip diff.
A mechanical torque vectoring system uses two clutches at the rear axle to overdrive
the outside wheel, with additional brake vectoring at all four wheels.
A little practice and you'll find you can keep your foot hard in it while first the apex comes sweeping towards you, followed by the exit kerb - which you can just rub with the two
outside wheels and listen to the satisfying rasp from the ripples in the concrete.
Graham Hill Bend is one of those corners where if you can get the car turned slightly early and loaded up by the middle,
the outside wheels weight up and grip harder and help you carry extra speed towards the exit, while the inside ones float over the kerb.
As much as 100 percent of the torque going to the rear axle can be directed to
the outside wheel to create a yaw moment and kill pushy understeer.
The inside wheels will describe a smaller circle, and therefore travel less distance than
the outside wheels.
With an active electronically controlled system like this, the car can immediately send torque to
the outside wheel to aid turn - in rather than reacting to torque input from the engine like a purely mechanical system has to.
The torque transfer from the inside to
the outside wheel is noticeable, but the effect is rather odd and, it has to be said, perhaps even unnecessary.
Acura's SH - AWD — This is a special case where they have devised a system to actually speed up
the outside wheel in a corner.
It can also transfer up to 100 % of the rear - end power to
the outside wheel.
At turn - in, the car shifts its load to
the outside wheels and the springs take their set for the corner.
The diff helps you to subtly work the rear through longer corners too, adding more traction as you feel the back load up on
the outside wheel.
It allows
an outside wheel to rotate faster than the inside wheel.
Volvo uses a torque - vectoring system at the S60's rear axle to send more torque to
the outside wheel in corners.
This limited allowance and compensation for differentiating rotational rates is called «limited slip» between the inside and
outside wheels.
Available torque vectoring works by braking the inside wheel (s) in corners, proactively transferring torque to
the outside wheels — which helps turn the car and improve handling performance.
Agility is further boosted by the torque vectoring differential, which shuffles torque to
the outside wheel to help fire the car out of corners.
However, the chassis has a curious tendency to wind itself into a lateral jiggle as
the outside wheels load up then unload.
If a vehicle's wheels are 1.5 metres apart (from the centre to the centre of each tyre), and the vehicle drives a complete circle of a steady radius — in this example 1.5 metres on the inner wheel —
the outside wheel travels on a circle with a radius of 3.0 metres.
You may also notice that the front wheels aren't turned at the same angle,
the outside wheel is turned slightly less than the inside wheel.
In essence, the inside wheel has to turn more slowly than
the outside wheel, which is covering more ground.
