What does VR6 stand for?

VR6 refers to a type of internal combustion engine configuration developed by Volkswagen. The "V" indicates that the engine has a V-shape, while "R" signifies its use of a narrow angle between the cylinder banks, typically around 15 degrees. This design allows for a compact engine size while still providing six cylinders, offering a balance of performance and efficiency. The VR6 engine has been used in various Volkswagen and Audi models since its introduction in the 1990s.
