Finally drove a 3.5T…honestly I was underwhelmed.

You didn't even take the GV80 up to freeway speeds and now you want to talk about performance and drag racing? Tuning a GV80? Dude... I'm done here lol

 

[Silverct9a]

Yeah because highway and drag are the same thing…Quit the bench/magazine racing and go out and break a fingernail while wrenching on a car dude.

These boosted Hyundais are severely detuned from the factory - Learning how to install that JB4 and loading an E85 map would be a good start for you to actually learn something that’s NOT in a magazine.

We drove both the 2.5 and 3.5 and noticed a nice difference in acceleration on the highway with the 3.5. There was also less engine noise, so that’s what we went with. We don’t really focus on gas mileage when driving an SUV so that wasn’t an issue for us.

I don't understand the performance concerns of some GV80 owners, the GV80 3.5T is a fantastic overall luxury SUV. My wife bought a new 2023 Lexus NX 350, great vehicle but compared to my GV80, the NX is a very "standard" featured vehicle. The GV has literary 100's of features that can be customized to suit your needs or wants. A simple example is the navigation screen on the GV80, you can change type size, colours, many many features, on the NX, you get what you see.
The GV80 3.5T has lots of performance if you understand it, Yes the turbochargers take time to spool up, so it seems kind of dead off the line. But try this, just come off a stand still normally and when you get to about 10-15 MPH, nail it.. But be where, the turbos are starting to wind up. Keep the petal to the floor for about 5 seconds, it downshifts to 1st gear roars to live and in about 2 second hits redline and pulls real hard in 2nd gear.
But we didn't buy our GV80 3.5T's for high performance, we bought them because we have a full featured vehicle at a very reasonable price.
And yes in my younger days (50 years ago), I was a drag racer and had a car that could run in the 10.5s at over 130 MPH. So I do understand performance.
Yes the GV80 is kind of slow off the line, Genesis could raise the stall speed up another 1,000 RPMs or turn up the turbos. But we did not buy the GV80 as a hot rod, Genesis gave us a great all round vehicle.

I tried both and agree there isnt much difference with the exceptions of some options which for me i might as well just get the extra options. I drove a 2.5 and it was real nice, It was a 2021 and had HDA2. My 2022 G80 sport prestige has HDA1 which is missing about 7 features that were supposed to be in it but ended not being in it. Some 2022 models have it some do not . I think Genesis should find a way to make that right but they never will. It is crazy that cars at half the price of Mazda, Ford, Toyota, and others had that and have that but a high end car like genesis does not.
Looking back at it now I should have just went with the Genesis G80 Prestige 2021 model but I did not like the tan interior at all and my wife was not a fan.

One other thing to note re: sluggishness off the line - and this pertains to both the 2.5 and 3.5 - an aftermarket throttle response controller can largely address this. All of these modern vehicles have accelerator pedals that are 'drive by wire', and the factory setups are designed to maximize gas mileage.

I have been using Pedal Commanders in all my vehicles for years. They are simple devices that plug into the module that controls the accelerator pedal and remaps the signals on pedal position going to the engine control modules.

There are various maps you can use, and changing them is via Bluetooth on your phone or on the controller itself.

Installation takes just a few minutes. I use the City mode which is a more linear map. The stock map that Genesis puts in these things requires much pedal depression before anything happens, which makes them feel sluggish off the line.

The good news about Pedal Commander is it works with all drive modes (Eco, Comfort, Sport). This simple thing really does transform the GV80. Link here:

The point of this whole thread was me discussing the subtle PERFORMANCE difference between the 2.5T & 3.5T GV80.

Drag racing and attempting to duplicate performance numbers is apart of performance my friend as you’ve eloquently demonstrated by posting magazine articles. Now all of sudden you realize you’re not talking to some car noob but someone who has real wrench time, it’s a problem discussing it?

Are you even aware of JB4 ECU tuning for multiple Kia/Hyundai/Genesis vehicles?

Put down the magazines and hit a track or turn a wrench dude.

I took my 2021 GV80 Prestige 3.5T in for service at my Genesis dealer (I purchased the vehicle in Dec/2020). It is still low mileage, roughly 33,000 KM or or just over 20,000 miles. Anyway, the dealer gave my a new 2024 GV80 Advanced with 4 cylinder engine.
What a different vehicle, it was gutless compared to my 3.5T. Yes smooth, quiet etc but really not fun to drive
I do know what performance is, I am an old drag racer, back in the 60s, I had a Chev powered Anglia gasser that turned the 1/4 mile consistently in the middle 10 seconds.
Later that day I picked up my 3.5T GV80 and what a difference,A real joy to drive.

I test drove both motors before we went with the 3.5. I didn't notice much difference around town, but then again I don't generally participate in stop-light Gran Prix events. Where I noticed the difference was flooring it at highway speeds - like passing on a two lane road. The 3.5 had way more high-speed punch.

This is basically where I need the power 99% of the time, which was why I went with the 3.5T.
