Volkswagen DADA specs: 1.5L (91.4 ci) 4-cylinder, 74.5 x 85.9 mm (2.9331 x 3.3819 in) bore and stroke, 11.5:1 compression. Rated 158 hp, 2022–2026.
The Volkswagen DADA is undersquare — the 3.3819" stroke exceeds the 2.9331" bore by 13.3% — a layout that trades peak RPM for leverage and torque low in the range. The 3.3819" stroke does not reach 4,000 ft/min of mean piston speed until about 7,100 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 4 cylinders displaces 22.9 ci (374 cc).
11.5:1 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 4 engines in the EA211 family, the largest at 91.4 ci. 5 factory variants share these dimensions, rated at 158 hp across 2022–2026.

Factory specification sheet.
| Bore/stroke character | 0.867 — undersquare — stroke exceeds bore, which favours low-end torque |
|---|---|
| Mean piston speed at 6,000 RPM | 3,382 ft/min — conservative for a street engine |
| Displacement per cylinder | 22.9 ci |
| Static compression | 11.5:1 — high enough that pump premium or better is normally required |
