Volkswagen EA888 specs: 2.0L (121 ci) 4-cylinder, 82.5 x 92.8 mm (3.2480 x 3.6535 in) bore and stroke, 11.65:1 compression. Rated 186-245 hp. DOHC.
The Volkswagen EA888 is undersquare — the 3.6535" stroke exceeds the 3.248" bore by 11.1% — 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 4 cylinders displaces 30.3 ci (496 cc).
11.65:1 on aluminum heads 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 EA888 family, the largest at 121 ci. 2 factory variants share these dimensions, rated from 186 to 245 hp. Factory fitments include the Audi A4 (B9), Audi A5 (F5), Audi Q5 (FY) and 8 others.
