Alfa Romeo's in-house V6 engine design made its initial debut in 1979 with the Alfa 6, eventually attaining fame under the hood of the 164 sedan/saloon. Initially introduced in 2.5L guise production engines would eventually range from 2.0 liters to 3.2 liters in displacement. With modifications it is possible to increase engine displacement to 3.8 L. Initially developed in the early 1970's by Giuseppe Busso the original SOHC 12 valve design employed short push-rods to operate the exhaust valves in a design similar to that of the earlier BMW/Bristol engines. In 1993 the first DOHC version of this engine appeared powering the Alfa Romeo 164. Image File history File links Metadata No higher resolution available. ...

This engine has since been replaced in the 159 sedan and Brera coupe by a new 3.2L V6 unit utilizing a General Motors-designed engine block and Alfa-Romeo designed cylinder heads and induction. While the newer, GM-based unit benefits from newer technology than the older design, including variable inlet and exhaust valve timing, it has proven to be unpopular with enthusiasts. This is attributable in part to the newer engines nondescript appearance and General Motors heritage. Enthusiasts also argue that the traditional, and well-loved, Alfa V6 engine note has been lost.
