					A V engine, or Vee engine is a common configuration for an internal combustion engine.
The cylinders and pistons are aligned, in two separate planes or 'banks', so that they
appear to be in a "V" when viewed along the axis of the crankshaft. The Vee
configuration generally reduces the overall engine length, height and weight compared to
an equivalent inline configuration.

In 1896, Karl Benz patented his design for the first internal combustion engine with
horizontally opposed pistons. Usually, each pair of corresponding pistons from each bank
of cylinders share one crank pin on the crankshaft, either by master/slave rods or by two
ordinary connecting rods side by side. Some authorities even regard this as a
distinguishing feature of a true Vee engine, and for example divide flat engines into
boxer engines which do not share crank pins in this way, and 180° engines which do. On
the other hand, some important V-twin engine designs have two-pin cranks. However, in
Germany, these engines are all identified as boxermotors.

Various cylinder bank angles of Vee are used in different engines; depending on the
number of cylinders, there may be angles that work better than others for stability. Very
narrow angles of Vee combine some of the advantages of the Vee engine and the straight
engine (primarily in the form of compactness) as well as disadvantages; the concept is an
old one pioneered by Lancia, but recently reworked by Volkswagen Group.
