The V6 is commercially successful in contemporary mid-size cars because it is less expensive to build and is smoother in large sizes than the inline 4,inline 6, which has better smoothness, or a flat 6 which has a lower centre of gravity.
which develops increasingly serious vibration problems in larger engines. The wider 90° V6 will fit in an engine compartment designed for a V8, providing a low-cost alternative to the V8 in an expensive car, while the narrower 60° V6 will fit in most engine compartments designed for an I4, proving a more powerful and smoother alternative engine to the four. Buyers of luxury and/or performance cars might prefer an
Recent forced induction V6 engines have delivered horsepower and torque output comparable to contemporary larger displacement, naturally aspirated V8 engines, while reducing fuel consumption and emissions, such as the Volkswagen Group's 3.0 TFSI which is supercharged and directly injected, and Ford Motor Company's turbocharged and directly injected EcoBoost V6, both of which have been compared to Volkswagen's 4.2 V8 engine.
Modern V6 engines commonly range in displacement from 2.0 to 4.3 L (120 to 260 cu in), though larger and smaller examples have been produced, such as the 1991 Mazda MX3, and the Rover KV6 engine.
