I think the biggest difference in US versions ( those are the only ones I know well enough ) is the front vents. QV's will have the long rows of vents in the middle of the hood, vs. gts/gtb I's will have just the vents on top of the fenders just above pop up lights.

most QV's have the rear spoiler.

QV's have the larger row of vent slots in on the rear deck as well. Europ cars just have two separate vents on the rear... US cars have them joined at the bottom I think non QV's just have the two as well.

inside is the easiest and biggest difference.

Non QV steering Wheels have a Nardi Wheel, QV''s have momo black wheels with MOMO engraved on the 6o clock post. also QV's have the larger glossy plastic horn button, Nardi have smaller metal prancing horse button.

Post Carb cars - first gen ingected cars have a square surround for the clock and oil pressure gauge just in front of the gear stick. its very after thought looking.... QV's have a rounded raised section for that in front of the gear stick.

QV's have larger non metric wheels - with larger Star pattern... usually Speedline made, Pre QV post Carb have larger dish smaller Star wheels - Campogaliano made wheels - but I think Speedline made some as well... QV's are 16 inch - but I believe they can fit all 308's...

Under the front Hood, QV's will NOT have a zippered spare tire cover ( US versions at least ) ... same for 328's.

intake on the engine on QV's are painted Wrinkle red with aluminum lettering and striping. also the airbox should say UFI & Ferrari. and be plain rectangle... but this is not always the case.. i think pre 84 QV's had the older style airbox.

 

I think only US models had anodized black front vents. Australia being RHD might have been the same as Japan but each country has it's own rules that may or may not affect cosmetics..

 

The front and rear bumpers are much diiferent as well.

 

US QVs in 1983 (at least) came with metric wheels and tires.

 

... although 16” wheels made by Cromadora were already offered as a factory option by 1983.

 

Just briefly browsed your database again. A remarkable amount of detail. Just remarkable; like nothing else before it.

 

Simon, if you're already talking to Carl888 then you've got a good source of info.

The Australian 308 QV’s are a bit of mish-mash vs. RoW. Cosmetically they are almost identical to the European market QV: Front louvres in body colour, same rear hood/bonnet, lenses / indicators, lower rear valance / exhaust, TRX rims / tyres standard (16” optional) etc. The external mirrors however are the larger Unilektra 'flag' style mirror used for the NA market (although who knows if there were some that sneaked in with smaller Vitaloni mirrors). Dashboard and controls are more or less same as EU. No rear demister option for AU cars.

Under the bonnet there were a number of differences to both US and Euro cars. AU used the NA market Marelli Digiplex, but a unique fuel distributor (it used the 208 Turbo unit, different to both EU or US QV’s), I think a different warm up regulator and aux air valve than US or EU, air intake duct with integrated intake silencer (like NA / Swiss cars), no Lambda sensor (same as EU, AU was pre-unleaded fuel at that time anyway), no EGR. I’ve probably missed other little regional differences here too (e.g. other Bosch K-Jetronic system components). I also had a note somewhere that most of the AU QV’s had the single belt alternator / water pump pulley.

Of course for Australia you know that we only talk about GTS QV's, there were no official AU deliveries of the GTB QV. Perhaps have a search through some older posts here too e.g.

PS. If you're buying a QV then make sure you pay a huge price so mine will be worth more! LOL.
Cheers

 

Another obvious difference are the rear louvers.

Not mine, Brian: it's "Triple Black"s effort; I am only assisting from time to time...

Yes Mike; we should add that the reason for that five extra row of louvres on the engine hood is simply the catalytic converter that the US Cars had, and the "Euro" did not. The five extra row of louvres were for extracting more hot air on US Cars' engine compartment, due to the catalytic converter(s).

There is a whole bunch different with the Australian 308's

We discussed this in another thread a short while back. Some of their governmental regs resulted in a 308 series as unique as their wildlife.

 

Yes I know about the louvers as why only the US has it and I know why Euro doesn’t, I’m just showing the other obvious different looks between the two. Question for you is, since I don’t have catalytic on my US QV, should I remove the five extra row?

 

I agree, 83 was a mix mash year from the GTBI/GTSI to QV's. they may infact have been standard and you could upgrade to larger wheels? not sure. most QV's that I've looked at had the larger wheels.

 

TRX wheels / tires are more expensive today. I think Cooker tires remakes Michelin TRX tires ... not sure on pricing.

 

The 16 inch was an option at some point in 83.

In fact, I think some early 84's still had metric

 

I have no doubt most QVs have 16" wheels now, but I don't know what the mix was from new. For sure the QV wheels sell for more than $4k a set and people use the metrics for hose reels and bonfires is telling on which direction the fleet is moving.

For sure in 1983 anyone who was buying wheels and tires in inch sizes while the world steadily moved to the metric system would seem a fool in 40 years!

 

My ’83 Qv, sold on Nov. 19, 1983 in California, came with 16” wheels and the original sales receipt doesn’t mention them as an option versus the earlier metric rims.

 

to my knowledge, there were no QV delivered in Australia in 1983. the first QV chassis numbered with still a 2v engine (!!) was a march 84 built.
I cannot explain this except because of the Australian regulations of this period.

 

Do you knows if another ''308 2QV" were made ?

 

No, only one is known. We've already spoke about that strange period for AUS 308s
