This is incredible ! Great sound MPZ does it again !

[@MPZRACEVIDEO]

Thanks!

[@PeterPretorius-]

Was für ein Geschoss... Und der Sound ist einfach gigantisch. Danke fürs Hochladen.

[@MPZRACEVIDEO]

Danke Dir

[@CossieGT3]

Great video guys... And one of my favourite racecars ever!

[@snockdawg82]

Straight from Gods mouth holy shit!

[@caseylockwood5512]

Awesome sound but I wish he would push the car more. You can tell the car is capable of wayyyyy more, the driver was being very conservative.

[@MPZRACEVIDEO]

Thats right, he was dirving just in the demonstration class without any time, and the Car is a Circuit Car with Circuit tyres they need a couple of kilometers to get temperature in. Its not to compare with the very soft special hillclimb tyres.

[@kushagrasingh9872]

You wouldn't want him to pull a Richard hammond

[@anhiirr]

damn somethin bout a quad cammed v8, and a straight cut gear box lmao.......so tasty the dream. Sounds sooo correct straight piped.....all you usually hear is the transmission with normal exhaust manifolds

[@PentaYOOO]

I love the sound of straight cut gears. there's just something about it, especially paired with a big loud engine

[@APICCIPUN]

you should have a listen to the Aussie V8 Supercars then ;). Big v8 + straight cut gears = Eargasm

[@grunta101]

Total Weapon!!! Many thanks for such a Professional Video:)

[@MPZRACEVIDEO]

Thank you

[@AndreiTupolev]

Lovely combination of engine & transmission sound.

[@kelvinwang5231]

such a good tune machine. Big downforce. Smooth on the corner

[@ericholder2026]

BEST CAR EVER!!

[@user-zs6gf2oe9v]

bmw 😍😍😍

[@alexhidell663]

What a beast!!!

[@floabr]

damn, this is unreal

[@midnoob1650]

How many mics do you think died thanks to that car?

[@ListlessSpectre]

This thing is just nasty sounding. Probably the loudest Z4 I've heard and your average GT3 is already breaking eardrums. This one must be absolutely deafening.

[@derkrieff9893]

unbelievable loud!!

[@arfshesaid4325]

some pretty pedestrian shit here, what a beast

[@fldon2306]

LOL! Love the engine roaring, but big V-8 are everywhere here in the USA, so hear this all time!!

[@jortepap]

omfg 😁 👌👌👌👌 love it!!

[@vale4691]

great car, brilliant sound, medium driver

[@miamibeach40]

ROCK HARD

[@esox1799]

What is the metal box in Front of the engine you See in the Ende of the Video where they show the open engine bay? Die the team supercharge it? Because normally the GT 3 was a NA car i think?

[@inox1ck]

Best gt3 ever

[@Veritas3979]

Why does this car seem "slower" than a built 1.8 hot hatch?

[@BeanDip96_]

The driver is definitely not pushing hard.. Could either be one of the first practice sessions on course, or installation laps for the car.

[@Veritas3979]

+Brandon Ryan Ah, would've been nice to see this car getting pushed hard.

[@95racing54]

A GT3 car is not built for Hillclimb tracks. A small hot hatch is lighter and performs better in slow corners. GT3's have much aero downforce but you need to have mechanical grip and a lightweight car at slower tracks. A built small hot hatch could be faster at hillclimb tracks.

[@MPZRACEVIDEO]

Thanks.

[@kokoloko12398]

Lovely sound ! One question : what make this "metallic" sound we can hear in background ? I mean "behind" the loud sound. Is it the transmission ? Why is it different from normal cars ? Thanks :)

[@JimmyTurboMods]

Yes it's the noise of straight cut gears used in racing gearboxes

[@kokoloko12398]

***** Oh I see, thanks ;)

[@TWIRKNOLOVE]

It's different because straight cut gears in the transmission have a stronger axial load than helical, which are quieter. The reverse gear in your car is straight cut though, which is why it whines when you reverse fast.

[@kokoloko12398]

TWIRKNOLOVE Oh it's clear now, thanks ;)

[@ameerramchand5606]

its the sequential transmission that has gears with straight teeth instead if helical . straight gear whine as you can hear

[@bmw3238]

💯👌💪

[@he4dhuNTeR2311]

Vor nem Jahr ist mir mal das Flexrohr abgerissen, war nicht viel leiser 😃 gut, der V sound fehlte halt aber war auch mächtig geil, vor allem auf Dr Autobahn 😃 runter schalten mit gasschub und dein vorderen wusste entweder Platz oder ich werde geschoben 😃

[@BESTMUSIC4YOU]

👊😎💤💨

[@gregoryrpm10000]

6i or v8???

[@95racing54]

4.4L V8 from the M3 GTS, max. power @ ~8300rpm. Unforgettable sound if you heard it at the racetrack :)

[@gregoryrpm10000]

+95 RACING Thanks!!!!

[@95racing54]

[@robreeves9825]

@@95racing54 Similar to the GTS engine but not exactly the same. GTS designation is S65B44 this is P65. P65 has flat plane crank and dry sump. Different internals as well.

[@froyothepro5615]

@@robreeves9825 why does it sound so much like a non-flat plane crank like the s65?

[@Tintop]

come on.. white rims on a Z4 GT3? ...needs to be black!

[@fredrikandersson3885]

engine sounds good but that exhaust note is ear piercing, not good.

[@ahimeirhadad4836]

Flatplane V8 4.0 = Camaro
