An internal combustion engine where all six cylinders are mounted in a straight line along the crankcase. This layout is inherently balanced, eliminating the need for balance shafts and providing smooth operation. It is highly favored in heavy-duty trucks and performance cars for its durability and simple packaging, despite requiring a longer engine bay than a V6.
