Penta DB

Penta DB was an engine model produced by AB Pentaverken.

The 1929 introduced engine was a side-valve engine with a cast-iron block and seven main bearings, and the first straight-six engine used in Volvos.

Four other variants followed after.

These engines powered all six-cylinder Volvo passenger cars and taxi cabs, as well as the company's small trucks between 1929 and 1958.
