The TVR 390SE is a sports car designed and built by TVR. It was introduced in October 1984. It featured many novelties not found in other 'Wedge' TVRs before and was also the most powerful one yet. It never received British Type Approval, so technically speaking the 390SE was just a 350i with special equipment fitted.

TVR is a British manufacturer of sports cars. The company manufactures lightweight sports cars with powerful engines and was, at one time, the third-largest specialised sports car manufacturer in the world, offering a diverse range of coupés and convertibles.
