The original Citroën Rosalie was a light-weight racing car that established a succession of records at the Montlhéry racing circuit. More generally the Rosalie was a range of three models/sizes of automobile that comprised the core of Citroën's model range between 1932 and 1938. The three models were originally designated respectively the 8CV, the 10CV and the 15CV, the numbers defining the cars' fiscal horsepower which in turn defined the approximate engine size of each model. After the introduction of the new Traction Avant, the lineup was modified and at the 1934 Paris Salon the two smaller models became the 7UA and the 11UA, now with the overhead-valve engines from the Traction. Starting with the 1933 model year Citroen offered the 1,766 cc 11UD diesel engine option.
