1981 Safir GT40 Mark V

In the 1980s Safir Engineering Ltd began replicating GT40s and got permission from JWA to call the new project GT40 Mark V.

Distinguished from the original cars, the Mark V used a new chassis design that was fabricated and didn’t make use of complicated pressings. The result is a car that the remarkably different from the original design.

Peter Thorp began with chassis GT40P/1090 in 1981 and continued to produce GT40s in series up until the late 1980s. The first four were completed with Safir tags while the remaining production were made under the J.W.Automotive Engineering Limited name.
