Its the Audi quattro, not Quattro. its literally printed on the car in the picture!
As far as I'm aware, it's an Audi Quattro. The "quattro" on the back refers to its 4wd system, not the model name

You know what. you might be right and I've been mislead by the internet forums all this time banghead
I'd been told long ago that it was the other way round and the car is the little q the system carried the big Q.

The Audi Quattro was the first rally car to take advantage of the then-recently changed rules that allowed the use of four-wheel drive in competition racing. It won consecutive competitions for the next two years. To commemorate the success of the original vehicle, all subsequent Audi production automobiles with this four-wheel-drive system were badged with the trademark quattro with a lower case "q" letter.

Also don't forget it actually lost to a RWD rusty Lancia in the manufacturers standings. :P

In order to take the Quattro rallying, Audi needed to build a minimum of 200 roadworthy homologation cars. These were 12.5 inches shorter than standard to improve handling, with carbon-fibre-reinforced Kevlar, fibre-glass and aluminium bodywork helping to trim almost 180kg from their overall kerb weight
Er, what about all the standard wheelbase ones that had been rallying since Group 4 days?

How did they manage to get the B7 RS4 so right and everything else (R8 excepted) isn't up to the same standard. What was it about that car that made it handle so well?

Was there enough steel in the 037 for it to rust?

The TT isn't actually quattro though as it's a haldex based system so not permanent 4wd. Rs3 the same . Indeed many Audi's now badged quattro are really haldex .
Strictly speaking, you're right, but to the average buyer, quattro just means four-wheel drive, so I doubt they would be bothered whether it's Haldex or not.

Being exceptionally dumb but what's the difference between the original Quattro system and the Haldex system used now?

“Proper” quattro is full time all wheel drive with a center differential. The center diffs used are of varying types depending on generation. Lockable open, TORSEN, or crown gear diff with controllable clutch pack. Its able to apportion torque between the front and rear axles to varying degrees, either mechanically, or via electronic control of the center diff. There is never any drive interruption to either axle. It’s more complex, expensive, and less fuel efficient. It is better for performance though.

Haldex is basically a FWD setup with a power takeoff from the front diff connected to a prop shaft that goes directly to an electronically controlled clutch on the rear diff that engages drive to the rear axle as needed. Haldex can’t actively apportion any more than a 50:50 torque split, and it’s reliant upon vehicle sensors and ECUs to engage the rear drive. Most of the time rear axle drive isn’t engaged and the vehicle operates in FWD 95% of the time. It’s simpler, cheaper and more fuel efficient though.
