Interesting Discoveries Thread (Good or Bad)

I've got a GT with 18" Michelin PSP's from factory.

I was not accurate enough: I'm talking about AWD, not RWD on 18" rims. Sorry for the confusion.

poor build quality?! while cleaning the windows I came across the rear door window (passenger side). I pressed hard and in a upward direction, wouldn't ya know I head a creak!! eeeeeeee was not expecting that, I could repeat it , mebbe a video to boot.

This may be very old but since I'm usually IN my Stinger, I've never noticed it. I was just driving behind a GT1 and whenever he put on the brakes, the top brake light flashed 3 times before staying solid. He wasn't tapping either, since the taillights were solid.

Any of you notice this? I'm wondering if maybe he was in a 2019 since he still had temporary plates on.

I seen that on some video reviews where bloggers moving fast on it. So I think every Stinger has it and it blinks only when you braking from the high speed. Most premium cars have that these days as I seen and even some non-premium as well.

Most if not all new police/fire and municipal vehicles that are in my neck of the woods have the same effect when braking.

But does it creak when you are driving? That is the only important question. I would be surprised if pressing "hard" on any moveable surface in one direction or another did not produce a "creak" noise or whathaveyou. The seals against the glass, the glass against the frame, the hatch lid against the stoppers/seals, etc. You can push hard enough to exert more force than will be applied by driving normally. If you want to test how noisy your car can be when pushed "hard", just drive into a barrier; that will create lots of noise!

Mine is AWD, not sure if that applies to your original posting, can't remember now.

Well, 18 AWD get the Potenza A/S, which have a top speed rating of 150 MPH. So the top speed in the Stinger is restricted to 140 max. RWD 18s get Michelin Pilot Sport "Y" tires, or 186 MPH plus rated, and the vaunted (advertized) top speed is 167 MPH. Of course, the staggered 19" rims also get the Michelins; they are "summer" tires, or ultra high performance. Come winter, they need to be swapped out for at least A/S. The Potenzas should be good to go all year round except in the most extreme winter conditions; even then, careful driving will probably see you through; if you don't try to drive in a driving blizzard.

I have the 18" wheels, GT, AWD, with Michelin PSP's. Sounds maybe this isn't common?

 

[Metalmania82]

Not sure if this was mentioned before in the previous 39 pages, but I really like the Smart Vent feature. Had no idea what it was, just saw it pop up on my screen the one day and looked it up in the manual. Pretty cool!

 

[Lou]

Funny you post that now. I saw the Smart Vent message for the first time not half an hour ago. I was wondering what it is. Time to hit the manual AGAIN.

 

[Metalmania82]

It basically automatically controls humidity levels in the cab and is able to automatically clear any fogging that might start on the front windscreen.

Cool! Thank you for the explanation.

my car has it.....

Indeed. Yours is the only Michelin 18" equipped GT AWD I've heard of. Now, why? I'm going to theorize one of two possibilities: Kia sends out strange once-off cars not seen on their "build" site or in any of their literature: color and interior combos not offered being one well known occurrence. Why not wheels and tires? So, you got a 167 MPH top speed without running 19s, just because. Or, someone wanted to buy your car and requested Michelins instead of Potenzas, and the dealership obliged, only to have the potential buyer back out. You come along and get Michelins instead of A/S Potenzas; but you still have 140 MPH as your top speed, as per the OEM tires. You won't know which is which until you find an opportunity to test your car's top speed. If it hits c. 140 and no further, then you'll know; visa versa as well.

A couple things, first a smaller diameter wheel will boost the speed on the speedometer. (you wont be going as fast as it says), Secondly I hope the michelins are ''Y'' rated if you post over 150,imho.
and this guys opinion as well,
Speed rating and load index

 

[Metalmania82]

I'll look at the speed rating later after work. And find time and space to attempt a top speed run.

 

[rocket23]

I'm not even going to bother....too many negatives...not a closed course, po-po on the prowl, some dumb ass in the way,deer people,what have you, and lastly it's not paid off yet,lol.

Well, it is total diameter that determines actual speed. And if the 19s have a higher aspect ratio (and they do) than the 18s, that just means that the tire sidewalls are an inch taller on the 18s. As far as I can tell from looking online, all the Michelin Pilot summer tires are "Y" rated. So the only limiting factor is which speed limiter Kia put on that particular car.

and what a gps will say next to the speedometer that would be interesting
