ATTN: Engineer nerd needed - 150mph@4k RPM

[BertBert2019GT]

This screen shot is from some clowns street race. OP said AWD — isn’t there a speed governor capped below this for AWD? Is this kilometers? Can the gearing do +150mph at 4k RPM?! Please educate me

 

[MerlintheMad]

Why do you doubt that AWD goes as fast as Kia advertises? I've taken my AWD to 155 MPH and it was still pulling c. 1 MPH per second. In 7th gear.

The max speed cap is assigned by the tires the car came with. A/S on a square 18" wheel setup got reduced to 140 MPH (even 130 MPH, it changed at some point).

No no no I’m not doubting the speed capable of the stinger platform I am (1) confused by the information I have read about an AWD speed limiter at 135mph bc AWD comes with 18” wheels and all weather tires etc etc and (2) curious about the gearing of the transmission because I would expect the RPM’s to be higher at 150+ mph. I have never and probably will never take my stinger to that speed. Did you happen to look at your RPMs when you were at 155mph?

I was interested in having the gear ratios and how 150mph@4k RPM is possible explained to me with crayons please

153mph would be between 4100-4200 rpm in 8th, which is right about where the rpm is in the picture.

Attached is a screenshot of the Stinger gear ratios and tire size entered into a calculator.

Not all awd come with 18” and a/s.

Depends on market.

Some come with ps4 on 19”.

(Ask me how I know).

Data is beautiful. Thank you

Lol, no way! I was too focused on the up and down road surface while I did a crazy thing I'd never approached doing in my life. But if I were to say what impression I had of RPMs peripherally, it would have been somewhere between 4-5K (that chart agrees with that guess).

What he said.

I Know that Kia advertises that the RWD Stinger with Summer tires from the factory has a top speed of 167MPH. It's obvious from the chart above that it isn't a limit of the gearing, but the questions remains if it is an aerodynamic limit or is it an electronic limiter, or a combination of both?

Pressed reply by mistake. But I’ll add I’ve had my AWD to 208Kph. It got there very quick and was pulling hard when I saw how fast I was going and let off. Don’t think I got out of 6th.

electronic limiter. I've been over 155 in "Mexico" and I was pulling about 1.5-2MPH per second Still. It would have very clearly gone over 167 if I had more road to use.

What gear were you in at that speed?

 

[nhcowboy28]

12th.

 

[G70LEbyAdoom]

to be honest, No idea. probably 7th if I had to guess. The car was in D and I was around 5200ish when I let off.

7th gear is likely, then. I was surprised that acceleration pull was still that strong at that speed. Without the limiter, and given enough straight room, I think that the stock 3.3L Stinger would reach either side of 180 MPH.

well my car is not even close to stock which is probably why it was pulling the way it was. there are accounts of people on here doing similar runs where they where pulling around 1mph per second or so around that speed, which would make sense. I never could try though cuz my car was limited to 130 when it was stock.

 

[STINGER]

I've taken my car up to 272km several times, both stock and modded. I remember I did 272km with 3 heavy passengers and completely stock. Obviously modded it hits the 272km limiter effortlessly and at the pace it was going it will definitely do 300km+ if the electronic limiter is removed.

6th tops out around +/- 260km and then 7th takes you to 272km were it stops.

My '19 GT2 AWD came with 19" staggered wheels and tires.
