Built primarily with racing in mind, the aluminium-bodied "100S" (for Sebring) model developed 132 bhp (98 kW) at 4700 rpm. Only 50 production cars were made, plus an additional five works development/special test cars which were hand built by the Donald Healey Motor Company at Warwick. The cast iron cylinder head was replaced by one made from aluminium and the overdrive unit was not fitted to the gearbox. Dunlop disc brakes were fitted front and rear. To keep weight to a minimum, there were no bumpers or hood (convertible top), a smaller grille and the windscreen was plastic. The 100S was also the first production car in the world to sport disc brakes at both the front and rear. The car was approximately 200 lb (91 kg) lighter than standard. The majority of all 100S were two-toned White with Lobelia Blue sides. However, a handful of cars where produced in other colors including Spruce Green, red and one single black 100S.
