Why does MAN have a lion as its company logo?
The logo of all MAN vehicles depicts a stylised Brunswicker lion. Since 1971, the lion adorns the radiator grilles together with the MAN lettering. The heraldic animal was integrated out of respect for the company Büssing, which was taken over by MAN during the same year.
