Another feature just noticed

[GRIFF]

I just noticed on my 2012 5.0 non R Spec that during braking and the final moment before the car comes to a complete stop, the braking system some-how seems to eliminate the last final jerk. Very subtle, but always noticeable to me.

Every other car I have owned always produced a small and sometimes very subtle abrupt jerk when the vehicle comes to a dead stop. Try as I may, I could never completely eliminate this on other vehicles.

The Genesis braking system seems to have completely eliminated this and the vehicle comes to a complete rest without any abrupt and very jerk at the last instant providing a completely smooth transition to full stop.

hhhhmmmmmmmmm......... I've never had that issue with any car unless I didn't reduce the brake pressure as the car was coming to a stop!

It is a very small and subtle thing, almost unnoticeable unless one makes them self consciously aware of it in a vehicle other than the G.

It's as though I cannot tell when the g comes to a complete stop! vey nice when I think to notice it.

ok, if you say so, I have never heard of such a system.

Want to guess how they do that????

Some auto transmissions give you a little whomp just as the car is coming to a complete stop. This effect is the tranny shifting into low gear, getting ready to accelerate again. I wouldn't call it a "feature" that the Genesis doesn't seem to have this problem.

I doubt there is any "feature" about automatically releasing the brakes just as you come to a stop. Among other reasons, it would be a safety liability.

I happened to catch a yellow light yesterday------one of those, do you gun it or get on the brakes hard. I elected the brakes. There was a very noticeable more abrupt braking force just as I came to a stop------as in any other car I've driven.

The phenomenon is the difference between the static coefficient of friction (higher) and the dynamic coefficient of friction (lower) between the pads and disk. As the relative velocity approaches zero, the coefficient of friction goes up, causing more aggressive braking at the very end.

You have a 5.0 R-Spec V8. The inertia is greater at the front. The big block says it all. You also have 4 piston calipers on each front wheel. I think the dynamic braking action of the car comes from the calipers. They are really huge, and probably more than the car needs for stopping. With 4 pistons your stopping power increases tremendously. I too have noticed the stopping power of the car when braking hard.

This is one feature I think Hyundai got right. Now if they would only work on their quality with respect to the corrosion of the valves in the ABS unit.

You may also just be noticing the impact of the anti-dive geometry of the suspension design. Just a thought.
