Well, here is the info from Audi site:
Turbocharged DOHC in-line 2.0 litre 4-cylinder with FSI® Direct Injection, variable valve timing and intake manifold
Displacement: 1984 cc
Bore: 82.5 mm
Stroke: 92.8 mm
Compression ratio: 10.3:1
Horsepower: 200 hp @ 5,100-6,000 rpm
Torque: 207 lb-ft @ 1800-5000 rpm
Perhaps it produces more torque elsewhere, but I doubt it seeing as every review publishes maximum torque at 207 lb-ft.
Manufacturers can work wonders with small turbos right from the factory. The problem is that the stock turbo is only as good. For any serious increase of power, a turbo swap is a must.

Look at the graphs that are closer to the bottom - they are for a factory car (I think), and the graphs above are for upgraded performance that the shop offers (basically, ignore them
for our purposes).Newer Volvos, I understand, also have similar turbo output (peak TQ from 1900 to 5000+ RPM).
In the old days, however, the torque delivery of a turbo was not as flat, and generally arrived between 2500 - 4000 RPM. And only fairly recently have the manufacturers been able to perfect the technology to the point where a factory turbo exhibits no noticeable lag, giving that instantaneous boost.
A good source of info is a turbocharging book by author Bell (forgot the first name), and i can look up the title of the book once i get home.
