V-6 Engine designs
A V6 engine is a V engine with six cylinders mounted on the crankshaft in two banks of three cylinders, usually set at either a 60 or 90 degree angle to each other. The V6 is one of the most compact engine configurations, usually ranging from 2.0 L to 4.3 L displacement (however, much larger examples have been produced for use in trucks), shorter than the inline 4 and more compact than the V8 engine. Because of its short length, the V6 fits well in the widely used transverse engine front-wheel drive layout. It is becoming more common as the space allowed for engines in modern cars is reduced at the same time as power requirements increase, and has largely replaced the inline 6, which is nearly twice as long - too long to fit in many modern engine compartments - and the V8, which is larger, more expensive, and has poorer fuel economy. The V6 engine has become widely adopted for medium-sized cars, often as an optional engine where an inline 4 is standard, or as a standard engine where a V8 is a higher-cost performance option.
