Audi BHE specs: 3.2L (195 ci) 6-cylinder, 84 x 95.9 mm (3.3071 x 3.7756 in) bore and stroke, 11.3:1 compression. Built 2004–2006. Used in the Audi TT.
The Audi 195ci (BHE) is undersquare — the 3.7756" stroke exceeds the 3.3071" bore by 12.4% — a layout that trades peak RPM for leverage and torque low in the range. The 3.7756" stroke puts mean piston speed at 4,000 ft/min around 6,350 RPM, which is where a production bottom end is generally considered at its limit. Each of the 6 cylinders displaces 32.5 ci (533 cc).
11.3:1 is high enough that pump premium or better is normally required.
It is one of 3 engines in the Audi 195ci family, all of them 195 ci — the differences between them are in compression, heads and rating, not displacement. 3 factory variants share these dimensions across 2004–2006.
