SRT TOMAHAWK VISION GT OT (Now available)

[GranTurismo guy]

The sound, actually, is way out there, in my opinion - as in, I can't reconcile it as being a V10. The only thing really making any sense to me about it is the 14000+ rpm engine speed, where any unevenness becomes somewhat dominant (think MotoGP bikes).

The "wide angle V10" comment caused me to raise an eyebrow when I saw it. What does "wide angle" even mean in this context, and what is the significance? Does this explain the sound? Didn't it compromise packaging in F1 when they tried it? It didn't affect the sound much, mind you.

Those five exhaust tips might actually turn out to have something to do with it...

The sound is confusing. At lower revs, you can here the f1 style v10 noise, but that quickly goes as it revs higher into a buzzy v8 sound. It's crap audio, though, and there could be more layers to it that we simply aren't hearing in this recording.

Now that I think about it, PD could release another update this month, GT Academy ends next week and the GT-R LM and Zytek need to show up in the UD at some point.

It is strange, but that's exactly what we should expect from the sound; I got the same behaviour with a quick and dirty synthetic sound I made based on the firing order I settled on in my "detailed analysis".

You get a very similar situation with motorcycles with uneven firing engines, or uneven exhaust groupings (like this and this, respectively).
(By my analysis, the SRT is even firing, but each exhaust pipe gets uneven pulses)

It's a perceptual effect, where any unevenness dominates as the rpm rises, making all engines eventually sound more like single cylinders (with a unique colouration) - the more unevenness, the sooner that happens. A theoretically perfectly smooth exhaust sound will never do that, but they don't exist.

So.... It should sound like a v8? And the fact it does sound like a v10 at lower revs?

Edit: both of those bikes are 4 cylinders and I expect them to sound like that

I don't hear a V8 note specifically myself, but I do hear the 5 cylinder tone break down into something else as the revs rise, which is normal for uneven sounds. It sounded more like a MotoGP bike to me at first blush.

Ever heard a drum beat (loop) sped right up? All the individual hits become indistinguishable, and the main perception of any "cyclic" sound (i.e. pitch) is that corresponding to the length of the loop (its fundamental frequency). Exactly the same perceptual effect in action.

In this case (and in the case of all the current AES cars), the base frequency is exaggerated by the overblown rasp. What you hear at part throttle is a closer representation of the actual underlying sound, and that applies to all the AES cars.

Hell yeah, you can buy a S with stripes. That's a plus in my book, and it's great that SRT decided to offer such an option for the car. It isn't lacking in the color department, that's for sure. Good find. 👍

Here are more pictures from the Tomahawk's presentation in Detroit, this time from the PitStop blog:

Well he was the guy working with PD directly, so I suppose he has driven the machines more often than others at the event.

Quite, he is SRT's head of engineering (IIRC), so he should be aware about how the car works.

And of course, he was probably under the influence when he allowed the X to exist...

Where's that from?

 

[RACECAR]

Exhaust Blown diffuser? Now that I didn't expect. Not exactly a future technology since it was (Temporarily) on F1 cars, but still interesting. That said of course, will we get the same kind of sound effects?




Perhaps not exactly the same, but likely similar at least (assuming the AES is good enough at present to imitate the constant flowing exhaust gas relative to the downshifts)

Well, some have already said that the Tomahawk does sound like a F1 car in lower revs, so with the aid of the AES system, it would be possible to emulate the Exhaust Blown Diffuser sound, albeit I do not know how accurate would that sound be ingame (I'm sure Griffith will help you more on this department). Again, we can't say much until we are able to listen to a clearer sound sample from the car...

Pfft, everyone knows that you have to go for the GTS Red w/black stripes for that best look. Or whatever that light (?) green color is, I'm curious about that one. Looks like something that came out of a Hemi 'Cuda...

The 2014 Viper probably has that green.

Sassy Grass Green?

 

[Niku Driver HC]

The 2014 Viper probably has that green.

Does it? I might want to check that one out. Still, it's unlikely that we'll get most of this car's paintchips, since the striped ones are unobtainable by any means (because well, they're striped), so the only paintchips one could get are the solid colors. If this car has them, that is?

Sassy Grass Green?

Could be, if that's a real color name... "checks color name" Oh yes, it is a real color. But I'm not sure that is the green found on the S' color list, to be honest. It seems to be a tad bit less brighter...

That green color could be Snake Skin Green:

I suppose i should cross my fingers and hope the SRT will be added in the next update, nothing else.

And I believe we now have the official release date of the Tomahawk. Surprisingly enough, it will come before the end of the Peugeot VGT Seasonal Event, but I am not complaining about that in the slightest. Beyond the SRT and perhaps a few bug fixes, I am not expecting much else to come with this, but I'll be happy to get the SRT, because I am really eager to see how well it drives. The S and the GTS-R more than the X, mainly because while it is extremely fast, the X ends up being a one-trick pony. A very fast car indeed, but it'll struggle in most tracks, simply because it has too much horsepower and top speed to make track navigation easy...

The first thing I'm doing when i get the tomahawk x is Putting a 50% power limiter on it. 400 MPH is WAY to fast to be fun for me. I'll probably limit the GTS-R as well.

It's probably the wisest thing to do if you want to appreciate the X's abilities. Not to its fullest, but its fullest is probably too high for almost anyone to appreciate properly anyways. I might buy another X, just to limit it, and keep one in stock guise, just to try it out once in a while. Preferably with some brave pills nearby... I don't really see the need to limit the GTS-R, as I view as a racing Veyron SS with much less weight, so it's still somewhat tangible.

And the other problem is picking a color for the S, since it has a good and varied list of colors. Maybe green or red w/stripes... Argh, it's easier to pick a color when most VGT cars come with only two or three colors...

Probably should have said a 1/2/4/8 cylinder engine instead of just v8.

Like I said the audio is crap and you can barely hear anything of the gameplay properly. That buzzy sound is very dominant and could be drowning out the 10 cylinder note because of all the additional noise.
