The Porsche flat-six engine series is a line of mechanically similar, naturally aspirated and sometimes turbocharged, flat-six boxer engines, produced by Porsche for almost 60 consecutive years, since 1963. [8] [9] The engine is an evolution of the flat-four boxer used in the original Volkswagen Beetle. [10] [11] [12
This configuration has been described as a six-stroke engine based on adding together the four strokes per cycle of the bottom piston and the two strokes of the cylinder head piston, but there are essentially only 4 strokes, just with an alternative form of valving.

The last flat-six-powered Porsche prototype was the Le Mans-winning 911 GT1-98. Since then, its prototypes have used V-4 and V-8 engines. Here's why.
One look at the images associated with this patent will instantly remind you of the Le Mans Living Legend design study (below) that was only just revealed late last year. New Porsche sports car ...
A boxer-style flat-six engine is able to have perfect primary and secondary balance.As in other six-cylinder engines, the overlapping of the power strokes of the different cylinders (with a firing interval of 120 degrees in a four-stroke engine) reduces the pulsating of the power delivery relative to that of similar engines with fewer cylinders.
