Audi EA288 specs: 2.0L (121.9 ci) 4-cylinder, 81 x 95.5 mm (3.1890 x 3.7598 in) bore and stroke, 16.2:1 compression. Rated 150 hp. Rod ratio and piston speed.
The Audi EA288 is undersquare — the 3.7598" stroke exceeds the 3.189" bore by 15.2% — a layout that trades peak RPM for leverage and torque low in the range. The 3.7598" stroke puts mean piston speed at 4,000 ft/min around 6,400 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 30.5 ci (499 cc).
At 16.2:1 this is a compression-ignition engine: the ratio is the heat source that lights the fuel, not a knock limit to be managed.
2 factory variants share these dimensions, rated at 150 hp. Factory fitments include the Audi A3 (8V), Audi A4 (B9), Audi Q5 (FY) and 1 other.

| Advertised HP | 150 hp |
| Bore/stroke character | 0.848 — undersquare — stroke exceeds bore, which favours low-end torque |
|---|---|
| Mean piston speed at 6,000 RPM | 3,760 ft/min — in the range typical of performance street engines |
| Displacement per cylinder | 30.5 ci |
| Static compression | 16.2:1 — high enough that pump premium or better is normally required |
