Volkswagen RV specs: 1.8L (109.8 ci) 4-cylinder, 82.5 x 84.2 mm (3.2480 x 3.3150 in) bore and stroke. Rated 100 hp, 1990–1992.
The Volkswagen EA888 (RV) is close to square: 3.248" bore against 3.315" stroke, within 2.0%, which splits the difference between a high-revving layout and a torque layout. The 3.315" stroke does not reach 4,000 ft/min of mean piston speed until about 7,250 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 4 cylinders displaces 27.5 ci (450 cc).
It is one of 31 engines in the EA888 family, the smallest at 109.8 ci. 6 factory variants share these dimensions, rated at 100 hp across 1990–1992.
