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.
[5] [6] The most common design of flat engine for motorcycles is the boxer-twin, beginning with the 1905 Fée flat-twin engine, manufactured by the Light Motors Company, which was the first production motorcycle engine. [7] BMW Motorrad have a long history of boxer-twin motorcycles, beginning in 1923 with the BMW R32 [5]
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
Unlike prior Subaru flat-6 designs, the EZ30 has a significantly smaller bore pitch (the distance between adjacent cylinder centerlines on each bank of the engine block) than the contemporary flat-4 EJ-series. The bore pitch of the EZ30 is 98.4 mm (3.87 in), [36] compared to a bore pitch of 113 mm (4.4 in) in the EJ series.

The crankshaft configuration varies amongst opposed-engine designs. One layout has a flat/boxer engine at its center and adds an additional opposed-piston to each end so there are two pistons per cylinder on each side. An X engine is essentially two V engines joined by a common crankshaft. A majority of these were existing V-12 engines ...
The standard Boxster is fitted with a new 2.7-litre flat-6 engine, and the Boxster S is fitted with the existing 3.4-litre engine but with revised performance. The 2.7-litre engine is rated at 194 kW (260 hp) while the 3.4-litre engine is rated at 231 kW (310 hp).
There is no such thing as 180 degree V. It is a flat engine. Period. What makes a boxer different from other flat engines (of which it IS a flat engine) is the manner of how the connecting rods join the crank shaft and the pistons. It's really that simple. Not all flat engines are boxer engines, but all boxer engines, so far at least, ARE flat ...
