2. Covini C6W
This supercar comes from Italy, and although it has six wheels, it does look handsome. The production commenced in the 1980s, but it was stalled due to lack of low-profile tires. However, there were some stirrings in 2003, and six to eight Covini C6W models were produced two years later. This vehicle comes with an RWD system, whereas under the hood it sports the V8 engine. Engineers used fiberglass and carbon fiber for some of its parts whereas, underneath the skin, you can find a tubular steel frame. The Covini C6W raced at the 2004 Goodwood Festival of Speed.
