1963 saw the introduction of an entirely new car called the Morgan Plus 4 Plus (Photo 47). This used a conventional Plus 4 chassis, but was fitted with an elegant glass fibre body made by E.B. Plastics Ltd., of Stoke-on-Trent. The car was not successful and during the four years that it was in production, just 26 were built. In 1964 the Morgan chassis was used as the basis for another radically different car, the Morgan SLR, a racing car designed by Chris Lawrence and John Sprinzel (Photo 48). The aerodynamic body gave a top speed far in excess of the 130 m.p.h. achieved by the Plus Four at Le Mans on the Mulsanne Straight.
