Audi EA897 specs: 3.0L (182.9 ci) 6-cylinder, 83 x 91.4 mm (3.2677 x 3.5984 in) bore and stroke, 16:1 compression. Rated 218-272 hp. DOHC.
The Audi EA897 is undersquare — the 3.5984" stroke exceeds the 3.2677" bore by 9.2% — a layout that trades peak RPM for leverage and torque low in the range. The 3.5984" stroke puts mean piston speed at 4,000 ft/min around 6,650 RPM, which is where a production bottom end is generally considered at its limit. Each of the 6 cylinders displaces 30.5 ci (500 cc).
At 16:1 this is a compression-ignition engine: the ratio is the heat source that lights the fuel, not a knock limit to be managed.
It is one of 2 engines in the EA897 family, the largest at 182.9 ci. 3 factory variants share these dimensions, rated from 218 to 272 hp. Factory fitments include the Audi A4 (B9), Audi A6 (C7), Audi Q7 (4M) and 9 others.

| Advertised HP | 218–272 hp |
| Bore/stroke character | 0.908 — undersquare — stroke exceeds bore, which favours low-end torque |
|---|---|
| Mean piston speed at 6,000 RPM | 3,598 ft/min — in the range typical of performance street engines |
| Displacement per cylinder | 30.5 ci |
| Static compression | 16:1 — high enough that pump premium or better is normally required |
