A V12 engine is a type of internal combustion engine that has twelve cylinders arranged in a V configuration. This design allows for smooth operation and high power output, making it popular in luxury cars, sports cars, and some aircraft. The V12 engine typically provides more power and torque than smaller engines, resulting in better performance. V12 engines are known for their distinctive sound and smoothness due to the even firing order of the cylinders. They are often found in high-end vehicles from manufacturers like Ferrari, Lamborghini, and Rolls-Royce. The complexity of V12 engines can lead to higher manufacturing and maintenance costs compared to simpler engine designs.
