A V6 engine is a type of internal combustion engine that features six cylinders arranged in a V configuration. This design allows for a more compact engine size compared to inline six-cylinder engines, making it popular in many vehicles. V6 engines typically provide a good balance of power and fuel efficiency, making them suitable for cars, trucks, and SUVs. These engines can be naturally aspirated or turbocharged, enhancing performance and efficiency. Many modern automakers use V6 engines in their lineups, as they offer a blend of power and smooth operation, appealing to a wide range of drivers.
