Audi CJXG / DNUE specs: 2.0L (121 ci) 4-cylinder, 82.5 x 92.8 mm (3.2480 x 3.6535 in) bore and stroke, 9.3:1 compression. Rated 292 hp, 2016–2023.
The Audi CJXG / DNUE 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).
9.3:1 is low by modern standards and generally happy on regular pump fuel.
It is one of 10 engines in the Audi 121ci family, all of them 121 ci — the differences between them are in compression, heads and rating, not displacement. 8 factory variants share these dimensions, rated at 292 hp across 2016–2023.
