Spot the difference: An S2 coupe and a Coupe Quattro

[Acidburn]

in addition to the above, driveshafts are different, gearbox and diff flanges are different, 3B tunnel is different but AFAIK CQ is the same as the ABY in that repsect, no strut brace or turret -> bulkhead braces, front struts are 52mm on the CQ not 55mm although AFAIK early 3Bs are the same. 3B gear ratios are longer and box is stronger, obviously ABY is 6 spd.... erm... i think thats covered it

Yup 3b ratios are a lot higher. Tho for some reason possibly I think the fwd 20v's have a higher ratio setup compared to the cq's. I have noticed stigletts car rev's higher than any 20v i've ever been in hence me questioning that the box/setup was right.

Is it the same casing just different ratio's or is the whole thing different?

Was just thinking if the internals are effectively the same, it would probably be just as strong as the 3b unit.

I think the external parts are the same its just the internals which are different, its still not a proper turbo box as audiman once said to me hence why its not as strong as the 6 speed which is a shame, the ratio's are brilliant for the engine especially 3rd gear and 115mph+ :mischeif:

I think your right about the FWD cars having a higher ratio, from memory there was also a difference between the 9020v and CQ20v. My CQ does about 85mph @4000rpms in 5th which is just daft IMO. S cars get much better fuel economy, especially the 6speeders.

The ratio's in my CQ are brilliant for "spirited driving" but appalling for everyday driving! You're right in saying 5th is not excellent for the motorway. However, getting to the top speed at max power is nigh on perfect from a purely performance point of view

For reference, my CQ at just above 7000rpm will hit 30, 60, 90, 120, 145ish from 1st to 5th speedo indicated speeds.

my CQ20v gets 35mpg..... i got to aberdeen and back on just over a tank and a half, didn' think S2s could do anything like that??

although i agree that the 20v would do better with an S2 box...

I think in the Uk, there would not be much point in trying to turn a CQ into a S2 as the prices are so low at the minute. If thats what you are trying to do.

There's five members of the CQ which I consider to have their own merits...

1. Top of the tree is the S2 of course - lets not bitch about 3B vs ABY, but its 2226cc I5 Turbo. Others in no particular order...

2. The V6 engined version is a very capable car - initially a 2.8liter (AAH) then also 2.6 version (ABC ?)

3. The 20V non turbo variant is also fantastic fun (2309cc 7A engine in UK and NM in some parts of Euroland)

4. 10V NG motor (2309cc) with KE Jetronic is a good going thing too

5. Last and not least is the KV engined version - the 10V 2226cc - shares same crank as S2. Good ol K-Jet. Fantastic burble.

Did I miss any ?

These are all rare and unique cars which IMO shouldn't be used to 'create' an S2 - unless they are a basket case which is unusable for anything else. I'd wager that its both cheaper and easier to buy a good S2 than build one from the distributed remains of several other donor cars.

2.8 in Q form only - there was no 2.6Q AFAIK.

I've had both the AAH and 7A CQ and IMO the 7A is a better engine and suits the car better being revvier and lighter but horses for courses
