I 'think' I felt a bit tighter steering in Sport mode especially compared to Comfort mode, which felt had the least resistance. Normal mode felt like a compromise between Sport and Comfort. Has anyone else gone through each mode? If so, would you agree?
There's a difference...maybe you just have overly powerful arms so it all feels the same 😎. One thing to note: if you switch modes while moving, it seems to wait until there's no steering input going on to make the change.
On mine, "Sport" feels about twice as heavy as "Comfort" at low speed (although it's not actually). "Normal" seems somewhere in-between...at low speed. "Normal" and "Sport" seem similar at higher speeds.
It does seem the settings don't just change the steering weight, but also the rate of onset for steering assist...as well as affecting how quickly steering assist is reduced as speed increases.
I've looked at it with the factory scan tool and the EPS module will tell you both the steering wheel torque and amount of assist torque as you're using the system. What I've found is that, standing still and steering the wheel, the steering wheel torque is:
Comfort: 1.65 ft-lbs max
Normal: 1.9 ft-lbs max
Sport: 2.2 ft-lbs max
It doesn't seem like a lot of difference but a person can generally perceive around 0.1 ft-lbs of effort difference.
I also looked at the rate in which steering assist as applied and it's interesting. In "Comfort" mode the steering assist comes in fast. A bit slower for "Normal", but fast again for "Sport" (but not as much of it).
