Each bank of a V12 engine essentially functions as a straight-six engine, which by itself has perfect primary and secondary engine balance.A four-stroke V12 engine has even firing order at V-angles of 60, 120, or 180 degrees [1] [unreliable source] Many V12 engines use a V-angle of 60 degrees between the two banks of cylinders.

The M-105 was the first Klimov V-12 engine design to use reverse-flow cylinder heads, forcing the induction system to be placed on the outside of the cylinder banks, with the exhaust system also exiting from the outboard side, with twin sets of "siamesed" exhaust ports adjacent to each other. About 129,000 M-105 and its variants were built.

William Thomson, later Lord Kelvin, is given the credit for coining the term "kinetic energy" c. 1849–1851. [6] [7] William Rankine, who had introduced the term "potential energy" in 1853, and the phrase "actual energy" to complement it, [8] later cites William Thomson and Peter Tait as substituting the word "kinetic" for "actual".

Honda has made a number of naturally-aspirated V12 engines designed for Formula One motor racing; starting with the 1.5-litre RA271E engine in 1964, [10] [11] and ending with the 3.0-litre RA273E in 1968.
In 1932 Lincoln offered for the first time a 447.9 cubic inch (7.3 L) L-head V-12 with a seven-main bearing crankshaft and 150 hp. The K-Series was previously available only with a developed version (bored out to 384 cubic inches (6.3 L) in 1928 and uprated to 125 hp for 1932) of the 60° V-8 which first saw duty in the 1920 Lincoln L-Series.
The National Highway Traffic Safety Administration is investigating reports of alleged engine failures in GM's 6.2-liter L87 V-8, an engine used in a wide variety of trucks and SUVs.
As a large scale manufacturer, Mitsubishi had a wealth of experience building engines, both gasoline and diesel, in V and straight engine block configurations during the war. One of their many examples was the air-cooled A6120VDe air-cooled inline 6-cylinder 14.4 L diesel and the SA12200VD air-cooled V-12 diesel (21.7 litres).
