A V6 engine, often just called a V6, is an internal combustion engine with six cylinders. The engine has three cylinders on each side called banks. The two banks form a "V" shaped angle. In most engines, the two banks are at a right angle (90°) or less to each other. All six pistons turn a common crankshaft. It is the second most common engine design in modern cars after the inline four.[1] It can be powered by different types of fuels, including gasoline, diesel, natural gas and alcohol.
The V6 is a very compact engine design. It is shorter than the straight-4. Many V6 engines are narrower than the V8 engine. They work well and are well suited to the popular transverse engine front-wheel drive cars. It has largely replaced the inline-6, which is too long to fit in many modern cars. It is more complicated and not as smooth as the inline-6. The V6 is more compact, and more rigid, but also more prone to vibrations. It is also becoming a high performance engine. It has high power and torque output like the classic V8, but has good fuel economy.[1]
