Covini Engineering is a small Italian carmaker founded by Ferruccio Covini. It is best known for the six-wheeled C6W sports car, which has two pairs of smaller front wheels, inspired by the Tyrrell P34 Formula 1 car. The idea dated back to the 1970s, the project was revived in 2003, and the prototype appeared in 2004. The C6W used a mid-mounted Audi V8 and was built in small numbers until around 2016. It is a low-volume manufacturer.
