The same engine also has a main page: Audi CALA.
Audi CALA specs: 3.2L (195 ci) 6-cylinder, 85.5 x 92.8 mm (3.3661 x 3.6535 in) bore and stroke, 12.5:1 compression. Rated 265 hp, 2009.
The Audi CALA is undersquare — the 3.6535" stroke exceeds the 3.3661" bore by 7.9% — a layout that trades peak RPM for leverage and torque low in the range. The 3.6535" stroke puts mean piston speed at 4,000 ft/min around 6,550 RPM, which is where a production bottom end is generally considered at its limit. Each of the 6 cylinders displaces 32.5 ci (533 cc).
12.5:1 is high for a production gasoline engine; running a ratio like that on pump fuel depends on chamber design and fuel delivery rather than the number alone.
It is one of 3 engines in the Audi 195ci family, all of them 195 ci — the differences between them are in compression, heads and rating, not displacement.

Factory specification sheet.
| Bore/stroke character | 0.921 — undersquare — stroke exceeds bore, which favours low-end torque |
|---|---|
| Mean piston speed at 6,000 RPM | 3,654 ft/min — in the range typical of performance street engines |
| Displacement per cylinder | 32.5 ci |
| Static compression | 12.5:1 — high enough that pump premium or better is normally required |
