Steering mode

[mkviken]

Searched but can’t find a definitive answer

What does steering mode actually do?

Is it only the weight of does it change the speed of the steering rack too?


I’ve been using race mode but find it feels a bit fake and doesn’t self centre in a natural way.

Feels more natural in comfort or normal but don’t know if it changes the speed of the steering. Might be in my head but feels like the rack is slower in comfort?

Thanks

Sport mode gives you a faster turn rate than normal or comfort. It also increase the amount of input effort needed though - presumably to dampen the steering or you'd be all over the shop.

The steering is fully fly by wire anyway - you are only turning an electronic position sensor, not gearing. The "weight" is just electric dampening.

Ok thanks so it does effect the speed of the rack.

Is that right, I thought these systems were still assisted, just electronically?  This cutaway looks like it still has a steering column connecting to a rack, but is that actually just connecting to a resistance unit of some sort?

Those cutaway pictures are of a mk6 Golf.

Its not hydraulic like the previous Golfs, its electrically assisted, I'd assume that means your rotational input is translated into mechanical effort by an electric motor, which allows for different steering rates vs input. Yes, the steering column is attached to something, but not directly acting on the rack. The feedback weight is controlled by the electrical motor.

Looking at this it seems the speed of the rack won’t change as the 2 pinion gears work in tandem

Sort of how I described

That's really interesting, thanks for the info

It doesn’t say anything about rack speed etc being changed, just the effort required and amount of self centring effect it applies.

Looking through that I don’t think the response or speed of the steering is changed, jus the effort required at the wheel and the amount of self centring is applied.
