Euro R32's and USA R32


Recommended Posts

US-spec cars have a larger MAF housing 3" ID instead of 2.75" ID,

a ribbed top dual lower chamber airbox instead of flat topped

single chamber box in the EU cars, and they appear to have some

extra emissions equipment in the spare tire well. We've got a

hump there, while the EU cars do not. Reportedly there's

a charcoal cannister inside the hump, to suppliment the

purge valve in the engine bay.

EU spec R32 is rated at 241 PS or about 236HP SAE.

US Spec R32 is rated at 240hp SAE.

They're both probably underrated, as there's no

evidence to suggest that it's anything less than

the Audi TT 3.2's rated 250hp. Stock performance

numbers for the TT and R32 are nearly identical,

with a slight edge going to the R32. US-spec R32s

apppear to be getting down the 1/4 mile track

both quicker (13.9-14.2 stock) and faster (96-98mph)

than their EU counterparts (mid-high 14's @ mid 90's).

Don't know what accounts for the difference yet.

US-spec R32s listed curb weight is 3400 lbs, to the EU-spec

3250lbs, but put a US spec car one on a scale and it's really

only about 3340 lbs. The weight difference is in front and

rear bumper rebar and perhaps additional bars in the doors for

side impact protection.

US bumper sticks out a bit more, but doesn't have headlight

washers. Doesn't have OEM HIDs. Doesn't have the VWR-spec

H&R springs and Bilstein dampers of the EU cars. Rides 10mm

higher and rear suspension is really soft.

The gauge cluster is different, US cars don't have the NAV/radio

information in the center MFA display, and we got Monsoon

AM/FM/tape/CD head unit with a 200 watt amp in the back, instead

of the VW NAV unit.

There are *rumors* that EU spec R32's have different cams

than US-spec, but I've seen no proof of it yet.

Maybe off-topic but I read Daemon's post with interest. Much has been spoken about the 6463 ECU "flash" here in the UK. I have always thought that VAG deliberately used different software in the Audi 3.2TT to ensure that they could ask a higher price (in UK) for what was purported to be a superior product with an extra 9 HP.

Last week I had 6463 flashed under warranty. The car is so different that it beggars belief. VW sold us all short because of corporate marketing strategies! Starting from cold my idle is now SMOOOOOTHE. 5th/6th acceleration has noticably more torque & best of all, I have a faster, smoother car with approx 27 mpg (& I monster it.....) as opposed to the 23/24 mpg from new. For all you guys out there, my car is a Jan 2004 3 door. The dealer assured me that 6463 was NEVER fitted to a factory 32.

Anyway, IMHO the 6463 flash is probably nearly identical to the ECU setting of the current 3.2TT. Power & most definitely TORQUE are up. I know that Daemon (Ian) claim that there is no difference between the Audi 3.2 & R32 engines but I beg to differ. The induction manifolds are slightly different. - Get 6463 under warranty guys.

Hi Rachel, I still pop in now and again just been a bit busy working on the car getting the latest upgrades planned and ordered.

Firstly a bit off topic but great to hear you finally have had the dealer sort things for you. I followed your trials and tribulations with interest. Either you got a Monday morning car or your VW dealer just kept digging themselves a bigger hole everytime you let them touch it. I was going to pipe up at one stage as everytime you took it to them it seemed like they would stuff something else up but thought it best to let you sort it out at your end to your satisfaction. Anyway hope your finally enjoying the car now .

Now to answer your intital question in relation to Ian's (Daemons)excellent info he posted.

The Australian spec car seems to be the bastardised brother/sister of both the Euro spec and the US spec car.

Our cars were definately built at the same time as the US spec cars at the very end of the run for the R32 and we got their suspension (rear monroe dampers and different springs with a 10mm higher ride height), US spec roll bars (16mm rear and 21mm front), Good Year GSD3 tyres and mirrors instead of the smaller euro spec mirrors and Michelin PS2's ROLLEY~14.GIF

But then we got the Euro spec MAF & Airbox and no hump (charcol canister) in the spare wheel well as well we also got the Euro spec bumpers and Gamma radio with 6 stacker in the dash with cupholder above it instead of monsoon like the US spec cars with stacker in the boot grin.gif (The yanks hate that we got those, they love their cup holders)

Our ECU code has small differences to both the US and Euro spec cars which we found out when APR Oceania used my car for R&D when they were developing the ECU upgrade. (I can ask Guy Harding exactly what these differences are if anyone is interested.) Where some US cars had problems with non starting issues after upgrading the code, no matter how hard we tried to duplicate the problems here my upgrade worked perfectly from day one as did Tabs car in the UK I believe. I think APR UK used his car for R&D also. When we did the initial dyno run on my car before we upgraded the ECU we basically got 250HP as Ian mentioned there's no evidence to suggest that it's anything less than the Audi TT 3.2's rated 250hp.

Other than those there are the obvious differences to the US spec and some more minor ones to the UK/Euro spec. We are right hand drive, don't have a sunroof option, only have 3 colour choices (Blue, Silver Black) have a much smaller dead pedal installed in right hand drive cars, and we have the euro gauge cluster, though we dont have the euro MFD or Satnav that shows directions in the MFD.

Thats all I can think of now but I'm sure there are more minor diffrences here and there that will come to light.

Cheers Alastair

Thanks for the info Al!

All I can think that you forgot to mention was that the Oz cars all come with the Konig leather interiors & cruise control.

I don't know if I got a Monday car as it seems a bit hard to believe they exist now with a "modern" car factory. However, I certainly got a "Monday" dealer - esp. the service manager. suicide.gif

Which is a pity - as the service foreman and the tech who did rectify the problems were quite competent.

As for now enjoying it - well took a fellow rev-head for a spin - up past "the ton" on a quiet bit of road this morning. Also it snowed here tonight, and I've only just got home (now 12:30am) from a party on the other side of town. A great 37km drive in the R! Haldex only cut in and growled twice (though the ice warning chime and snowflake came on at engine start). ECLIPSe.gif169144-ok.gif

BTW, in a recent front page article on the Vortex


Jamie states:

"While we don't like to speculate, we've heard through various sources that Volkswagen of America and Audi of America decided to save costs during EPA certification of the R32 and TT 3.2 and gave them both the same engine management programming (minus a few changes for the standard DSG transmission on the Audi). Audi markets the TT 3.2 with 250hp while Volkswagen of America markets the U.S. R32 with 240hp."

As for the TT3.2 intake manifold. It's identical to the R32's.



Notice that the R32 even has the same 3 sided "thing" near the

throttle body, but it's just a plug for the R32, whereas the TT

uses it for the PCV return line.

This R32 picture shows that is different in my car. Where is it from?

Have you ever pulled the engine cover off? It's just a big

piece of plastic clipped onto the intake manifold, and if you

grab it at the edges and pull straight up, it'll pop right off.

Whilst the cosmetic plastic intake covers on the Audi & VW are identical, the inlet tracts are most certainly different.

[/ QUOTE ]

You don't get it do you. Both cars have plastic intake manifolds.

You're *looking* at the intake manifold runners in the above

two photos. Only the R32 has an extra plastic cover over the top

which I removed to take the R32 photo.


This is quite obvious if you look at the difference in the alloy outlets (throttle bodies?) in Daemons photo's. ooo.gif

[/ QUOTE ]

Obviously you're not looking at the photos.

They're identical. I'd put money on it. The only difference

is that the throttle body of the TT is rotated 30-45 degrees

rearward, probably due to space constraints. In fact, if you

go pull the cover off your R32 manifold, and look at the

coupling between throttle body and manifold, you'll see there's

4 extra holes in the manifold which would allow you to rotate

the throttle body and remount it *exactly* the same way it is

on the TT.

Now when's someone going to measure the inside diameter of a

Euro-spec R32 throttle body?

What is this section (highlighted) on the Audi 3.2 TT engine and why doesnt the R32 3.2 engine have this?


Also i recall that because of the new weight increase of the new Audi 3.2 TT the tyres had to be changed, Michelin made the Pilot Sport 2`s for this purpose as the old Pilot Sports could not handle the load.

If so why do the R32`s still come with the older Pilot Sport tyres and not the newer versions?

That's the PCV return line back into the intake manifold.

The R32 has it coming from the other side of the engine, around

the back where it enters the intake just in front of the throttle body. On the R32, that triangle is just a plug.
