The Invicta Tredecim was a concept car built in 1984.
The Tredecim was a replica of the Jaguar XJ13 built on the Jaguar XJ platform. It was a coupe sportscar, being a one off trying to revive the Invicta name, due to the high costs of the project the company had to shut down and so, this is the only to have been built.
Being based on a Jaguar XJ, it has the engine and drive-train from a 1984 Jaguar. The body was made of kevlar and painted red. The interior was black.
