Off the top of my head:

Mercedes CLK LM: The Le Mans engine which is used in the model (not the FIA GT1 version with the flat plane crankshaft) should redline at 7,000 rpm. Meanwhile, on all specs sheets on Google, it lists the 8,900 rpm of the FIA GT1 engine. With the Le Mans cross plane crankshaft engine, for me it sounds very unnatural above 7,000 rpms.

A solution for PD would be to decrease the redline for both models to 7000 rpm. Correct me if I'm wrong. Feel free to add more cases.

I assume this includes gearbox and exhaust sound? ;) I „complained“ about this before but if the intention is to make a collection of all the inaccuracies in one thread then please see below.

Mercedes-Benz A45:
The iconic pops and bangs and crackles are missing in the stock version. The model in game does have the AMG Performance Exhaust which was very popular. When i drove this IRL i could also hear the gearbox (like in race cars), however it is very difficult to find videos where this is audible.



Golf GTI:
I own this car IRL and the in game version is missing the typical VW DSG upshift bangs. But other than that it sounds very accurate.




I might add some more later…
 
Speaking of flat plane crankshafts, the S550 Mustangs. I know Mustang sounds can vary depending on the set up but I think they just used the Shelby GT350R sounds for both cars.
 
Mercedes Sauber C9: In the game it seems to go to above 8,000 rpm, while on spec sheets of the real life version, it says 7,000 rpm.

With both the CLK LM and the C9 (and I haven't found any good quality recordings of the CLK LM in cross-plane trim) I wonder if its the case of the real life cars being short-shifted in the videos. That makes sense both in the context of endurance racing as well as doing demonstration laps in historic cars - I'm sure there's typically an agreed-upon rev limit for engine preservation. I'm pretty sure a race prepared M119 could touch 8,000rpm considering its massed produced descendent/cousin, the even larger M159 could rev to 8,000rpm (SLS BS) in road trim with expectations of lasting 100,000+ miles.

I tried changing the gear ratios of the CLK LM so that short shifting is possible, but it felt sluggish. Have you tried it? If you find some good settings, let me know. I don’t know if it works like that, but the powerband of the engine isn’t working well with the lower revs. I don’t know how it would have been irl.

And I think the reason that there’s no good footage of the cross-plane CLK LM is that they probably put the flat plane engine in there right after Le Mans for the GT1 rounds.

I found this LM which sounds like a cross-plane V8, but hard to say exactly which crossplane V8.



In any case, I'm glad PD elected to use the cross plane variant of the LM, as it's definitely more distinct than the typical flat plane V8 used in many race cars.

I wonder if @SuperSportX has more info...

Amazing find! Can’t hear the rpm’s going over 7500 in this one either. I’m not sure if @SuperSportX knows about this car as much as the CLK-GTR. ;)

The CLK-LM used in GT7 is a FIA GT chassis, infact the exact same one in this Goodwood video:


The car should sound similar to the Audi DTM, which i'm only using as a comparison as it's the closest sounded car currently ingame if they wanted to just swap the sound out. The ingame model seems to have been scanned off the CLK-LM when it had the GTR wheels still installed which I believe was sometime in 2015 and is a FIA GT chassis meaning it isn't one of the ones used in Le Mans, same as the road converted one as that clearly sounds almost exactly the same as the one used at Goodwood:

Clearly we have seen that they have access to these cars but for whatever reason do not record the audio from some of them; as the Alfa Romeo 155 DTM has pictures of it being scanned by PD yet the ingame sound is nowhere near correct. While yes the LM in Le Mans spec which by the way isn't even the chassis they scanned does indeed use a motor based off the Sauber C9, it sounds pretty different from it instead of simply just revving higher which is all they did for the LM in GT7. Similar to how the CLK GTR GT1 and the Zonda R share a motor yet they sound quite different, which is yet another car that sounds pretty bad in GT7 as if it was correct it would be one of the loudest and mean sounding cars in GT7 if not the craziest rivaled only by the Valkyrie.
 
One of the first that comes to mind for me is the SC430 GT500. In-game it just uses a copy of the RC-F GT3's cross plane V8.

Whereas in reality the it had a far better sounding high revving flat-plane V8.

Disagree with this. The Goodwood car sounds like a flat-plane crank, and the converted road car sounds like a cross-plane crank.

Some sounds should absolutly improve. But my biggest grip will still be the pitch glitch on some of the cars. I hope this gets resolved for gt8 through.

Sounds are still pretty good for the most part.

I agree that most of them are good.
In case someone from PD is reading along my „wishlist“ (for a GT7 update or for GT8) would be:
  • Make race exhausts much louder than the others
  • Add distinctive sound features like pops and bangs for cars that have them with their stock exhaust (see my post above, examples: A45 AMG w AMG Performance Exhaust, C63 AMG, Golf GTI; i am sure there are many more)
  • In general: Review all sounds and update if the recording is too old (some are copy&paste from GT Sport which was released in 2017)
  • Not all cars should have pops, bangs and crackles (even with race exhaust)
  • Not really a sound thing but not all cars should rev-match when downshifting; a standard (non dual clutch) automatic transmission does not do that
  • Review idle and low rpm sounds (some are much too quiet)
  • Record the cars in sport/race mode, not in normal/eco/comfort
 
I dont really recall the vtec sound from Honda being accurate either, in real life it's much more pronounce, I had a friend who had a civic type R and you could really hear it once you were past 5.5k, in GT7, you barely hear any difference.

Stock sound pretty accurate but not much changes once you upgrade them witch is a shame.

The only type r that changes after you upgrade it is the fl5 type r.

I am talking about the pitch.

Fully agree. I dont see much changeing before gt8 through. I want to see the pitch glitch for some cars getting resolved through and Hopefully its getting fixed for gt8.

The cars that get the sound changes as you increase the rev limit can sound absolutly insane.

Ford Mustang gt/gt350r and many of classic muscle cars sounds way to muted even with upgrades and is proably one of the more dissapointing sounds in gt7

Many cars have a trait where sound pitch does not increase despite fitting upgrades that increase redline. FK8 vs FL5 Civics are perfect examples. Same engine, totally different sound once upgraded.

I tend to choose vehicles, these days, by this metric. After watching your video on Youtube (LOVE your content, btw... Never stop), I have taken to testing which vehicles have this limitation, and temporarily avoiding them while I enjoy the more raucous sounds of the well implemented engine notes. The sound goes a long way toward enjoying a long race, in my opinion. Furthermore, your videos have even helped me work out some tuning mistakes I had been making in the past. So, top marks there.

As for the topic of this thread, I would say quite a few of the American V8's don't have a very representative engine note. The one drawback of GT7's sound modelling is the lack of low end. GT has long had an issue with this, but in the past the overall sounds were so inaccurate (i.e BAD...lol) that it was a bit of a moot point. Now that the overall sound design has been vastly improved (most vehicles are reasonably accurate) the lack of low end really sticks out, especially with the big V8's.

The only type r that changes after you upgrade it is the fl5 type r.

That's true for the road cars, certainly. However, the Civic Type R Touring Car definitely changes with upgrades (Rev Limit). One of the better 4 cylinder engine notes in the game, in my opinion.

All you have to do to solve the problem is put the 1998 Le Mans livery on the car.

@SuperSportX - Well I stumbled on this video in an old GTPlanet thread. Definitely a cross-plane V8, and it definitely sounds like it's being short-shifted.

Click to expand...

Sounds amazing! It might be short shifted, but I think it revs to 7500 rpm max, not 9000 don’t you think? Do you drive it with adjusted gear ratios in GT7?
 
Worth pointing out THAT particular CLK LM from what I remember reading is a former test mule (note the singular exhaust as opposed to the two Regular Exhausts, which are covered up on it even in its converted Road Car state) that does not use the GT108B from ANY of the other 5 chassis (including the lone Road car in its flat plane configuration), but a modified variant dubbed the GT108C unit that would end up in the CLR (which likely explains the shortshifting in its case as its the earliest unit in that particular car.) I suspect PD just recycled the engine sample from the C9 (Likely under the logic that its just the same engine just without the Turbos, which it kinda is) and modified it to fit the car sans turbos. Wouldn't be the first time PD has used the exact same engine sample for multiple cars.

One of the first that comes to mind for me is the SC430 GT500. In-game it just uses a copy of the RC-F GT3's cross plane V8.

A more eggregious example of that pointed out here, which is maddening because its NOT the exact same engine in both cars (The SC430 GT500 uses a 3UZ-FE V8 while the RC F in both Road form and GT3 form uses a 2UR-GSE V8). Curious decision considering how buddy buddy they are with parent company Toyota.

They only sound close when you hop in the car in your garage and it fires up. Once on the track, it’s not accurate. It’s not raw enough and sounds like a sample ramping up and down in pitch. The best I can describe the lack in sound is it’s like you can’t hear the combustion. It would be tough to replicate since there would be a randomness there in real life. Every explosion isn’t going to sound exactly the same.

We run into this problem with electronic drums, they do a similar thing. Sample a drum at different velocities and then when you play it back, it sounds less real because you’re not hearing the stick hitting different spots of the drum head or the head being struck at a different point during its vibration. So when you do fast drum rolls, it has a machine gunning effect. They also sample somebody hitting a drum in the same spot at different velocities. There are so many variables, they could do it, but it would take up too much storage space.

I think this is what’s happening with the engine sounds in game. They can’t replicate the variables. The weird thing is, other games have managed to get a lot closer. GT Legends back in the day had about the best sounds out there, funny thing is, Gran Turismo has only now caught up and that was almost twenty years ago GT Legends came out. Actually it might have been twenty years ago!

And I agree, I didn’t okay GT Sport, but all previous GT games were sooooo bad with the engine sounds. But you’ll have the fan boys arguing however they can to justify the bad sounds of previous games. GT6 and down had BAD sound.
