In 1932, Leo J. Shorter became chief engineer (by 1940, technical directorWise, p.2071.). He and two other designers created the new Sports Nine Sports, which made its debut at the London Motor Show that same year; it featured a two-bearing crankshaft engine of 972cc, which gave the car its name. Owing to manufacturing difficulties of the new bodywork, the "9" engine was fitted to a number of Junior chassis' as a stopgap until the production cars were ready, which gave rise to the incredibly rare "Junior-Nine". The production numbers are unknown, and only 8 are known to have survived. And in 1933, The Nine was joined by a new six-cylinder, a 1.5 Horsepower six-cylinder, and a 2-Liter six-cylinder, while the Junior was dropped and the new sidevalve-engined 12 displaced the Ten. The Sports Nine was "an immediate success" among trials racers, and Singer entered a specially-prepared version at Le Mans, which led to the Nine being commonly called the Le Mans. Singer earned an "excellent reputation" in racing before three works Nines appeared at the 1935 Ulster Tourist Trophy, where all three wrecked, all from the same cause (steering failure) and all, incredibly, at the same spot. All the drivers literally walked away unscathed, but Singer's reputation in racing was beyond repair
