Okay, so as many of y'all know, Genesis is ditching the beloved 5.0 v8 in the upcoming 2023 G90 in favor of a 3.5tt v6. So I thought about it. I love the interior drive and features of the new G90. But what if we could swap it for a 5.0 v8 and 8 speed trans from a 2022? Thoughts? If it had a v8, it would be one of the best cars in the segment.

Where are you sourcing the parts? doubt there are many used ones in junk yards so that means buying new. What computer will you use or can it be reprogrammed?

You can have a wet dream about it but the cost would not appeal to many. I'd guess anywhere from $20k to $30k and little to no factory warranty.
 
Of course it's possible, how much money do you have? lol... that's always the issue
 
Go for it.
 
Or you buy a JB4 box for the 3.5T and make more horsepower and torque than the v8 could ever hope to have made. Total cost: about $700.

Zero wire splicing, totally removable if needed, and the platform can make well over 400 horsepower and torque to the wheels without touching a single piece of hardware. You would never miss the v8.

That's an option but a car like this isn't about the power. It's about a smooth engine that makes the right noises and vibrations. And in some ways, owning a car like this is about the excess..
 
Sorry there, Robin Leach. I don't know my place among the commoners. My suggestion is somehow silly but the idea of an engine swap in a brand new 2023 vehicle totally passed your feasibility test?

The turbo v6 delivers equal torque and makes it just off idle, powering any large vehicle away from a stop with zero fuss. You can accomplish at 10% throttle what you'd have to do at 50% or more in the v8. That is luxury to me. With the tune the difference becomes comical, barely twitching your foot to go anywhere you want to in traffic with double the v8's power for the majority of the rpm range. With factory exhaust I don't hear any difference at full throttle between a v6 and v8 so when does the luxury come into play?

I mean, I do drive a 2013 version of the same v8 (with barely 31k on the clock) so I must not be familiar with more modern options - even though my sig shows a 3.3T G80 Sport and 3.5T GV70 Sport Prestige so I've clearly experienced all of Hyundai's engine options. My brother's CL65 has a twin turbo v12 for when I want to experience actual "excess" -- and even Mercedes has abandoned that engine now and relies on a 3.0 6 cylinder in the current S-class.
 
I said it wasn't about the power... so my comment about excess... wasn't about the power.... I never said your suggestion was silly, it just wasn't what the OP was looking for.

And my reply wasn't about the power. It was about the silky smooth delivery a turbo v6 provides that a v8 can't match. That's where the part about making peak torque just off idle comes in - it's seamless like an electric motor, providing instant response from anywhere in the rpm range that a naturally aspirated v8 simply can't do. It's why Mercedes and BMW rely on turbos these days.

Anything less would be uncivilized. (with apologies to Right Guard)
 
I was referring to engine balance when talking about a smooth engine. BMW and Mercedes don't have V6s in their cars because they can't run as smoothly as an inline 6 or a V8. BMW has never had a V6 gas engine and the only V6 Mercedes gas engines were of the Daimler Chrysler era of cost cutting.

A turbo V6 does not have the same power delivery and smoothness characteristics of a V8...and MANY luxury car buyers in the full size category prefer a V8

Let me also remind you that the G90 does not have the driving dynamics for any high spirited driving. Its more about low end grunt and smoothness...Not a high revving /peaky power train

As for Mercedes and their V8..you are not accurate
Mercedes still offers a V8 in their current( 2022) and former( 2021 S class)
They have had smaller /more efficient engine available for years( decades) in the S class
However the lion share of their buyers, in the United States, go for the V8. Ditto with the BMW 7 series

BMW and Mercedes benz have has 6 cylinder gasoline ,diesels and hybrids available in their cars for decades

In the United States though, no one really buys them. They choose the V8( or V12) in an overwhelming majority of situations

Those choices will be going away as the CAFE get tighter. Forget raw power, it you can save weight the lighter engine will have to do. EVs may offset some in the future.
 
OP, this sounds like the wrong car for you. No shame, we understand. Move along and live life. Time is short enough anyway. No need to waste it on something like this.

Perhaps they will....one doesn't know anything for sure about timing and availability

What I will say is that in the United States... current( and prior)buyers of premium large vehicles/SUV's will choose a V8( or V12) the overwhelming majority of the time

Look at what the Big seller in regards to $100K SUV's ( the Escalade) has for engine
Then we can go even higher priced with the Range Rover and Mercedes G wagen
Heck even Jeep rolled out their latest flagship with a V8

Mercedes rolled out the new S class with an available v8...and I going to bet they have a V12 coming
They also have an EV for those that desire
I am going to bet the lions share of the cars they sell will be V8 equipped, as has been the case for decades now

You are FAR better off buying a higher end/ more expensive vehicle that has a V8 power train

You are looking at a high cost, high status auto that may be offset by other models. Do you think it is a fair comparison to the G90? Do you think they are going after the same market?

Mercedes can justify it just to keep their reputation. They sell enough Smart cars to offset it. It would be like Tiffany not selling diamonds because they think they are too gaudy.

So you saying that the new Mercedes S class buyer is not looking at the G90?..OK, I have said for years
As far as being " offset" by other models Hyundai has a lot more lower cost , high fuel economy cars, and much higher sales volume on the lower end....So if anything the " offsetting" should benefit Hyundai

Mercedes sells a lot more Mercedes Benz cars than smart cars ..orders of magnitude less worldwide

I am going to guess that Mercedes sells V8( and V12) cars because their buyers want them and will pay for them
I am going to assume the same thing with Tiffany's and the diamonds
They are both FOR PROFIT companies

But being that most of the G90's sold have been 6 cylinders anyway, its a moot point, and clearly its not really an issue with the market looking at buying it

It looks to me like Hyundai/Genesis focus their resources on what matters, to maintain a high bang-for-your-buck ratio and to keep costs down. The new G90 has tons of great features and lots of tech, but is very light on gimmicks - which you'll find plenty of in the S Class, A8, 7 series, etc.

If you drive a current V8 G90 back to back with a V6 G90... there is a difference, but it's minor. CAFE is tough and getting tougher over time, V6s are more than adequate, with the e-supercharger they respond better than V8s do, and having one engine simplifies manufacturing and engineering a lot. Unfortunately for those of us who like V8s, they're going away and it's inevitable. You might be able to hold on for a few more years if you want to pay up for a Mercedes/etc., but even Mercedes has started removing the V8 from a lot of their expensive cars over the last 1-2 years.

The fact is, Hyundai has chosen to get rid of the V8s now. No amount of complaining will bring it back. Don't like it? Too bad. That was a bit harsh, but it's the truth.

And buying one of the German cars, or a Lexus if they still have V8s on the LS, will be much cheaper than retrofitting a V8 into the new G90.

Why is it that half the threads on this forum end up turning into massive flame wars / arguments about a completely unrelated topic? The OP was asking if you can put a V8 into the new G90, the answer is (basically) no. End of thread. We're not going to be able to convince the "luxury cars need V8s and anything less is for peasants" people that V6s are fine, and they're not going to be able to convince us that V6s are a plague upon the car market and that whoever decided to put V6s into luxury cars needs to burn in hell. No point in wasting your time on this.

Yes, they have 6cyl engines... I was saying that aside from a few Mercedes engines during the dark days of Daimler Chrysler, none of the BMW or Mercedes 6cyl gas engines have been in a V configuration. They're all inline 6's.

BMW does actually make V6 engines, they have a corporate policy to build and research V6 engines every couple of years but they never meet their standards for noise and vibration so they're scrapped and never make it to market.
