The Praga Alfa was the name used by Praga in Czechoslovakia for one of its principle car ranges. Production started in 1913 and finished in 1942.


The Alfa was initially conceived as a cheaper and smaller complement to the Praga Grand and Mignon. Production was halted during World War I but resumed in 1923.[1] In September 1927, an Alfa with a larger 6 cylinder engine was introduced, followed by a completely new model in October 1937.[2]

Introduced in September 1927, the Alfa 8/25HP was a more powerful development of the pre-war Alfa. The car introduced a 25 kW (34 hp) water-cooled 6-cylinder engine with a removable head incorporating Ricardo combustion units. It was the smallest 6-cylinder engine produced in Czechoslovakia at the time. It had rigid axles, drum brakes and a front-mounted 40 litres (11 US gal) fuel tank. Top speed was 80 km/h (50 mph) and fuel consumption was 11 l/100 km (26 mpg‑imp). Cost of the car was 64,000 CSK. 2500 cars were produced between 1927 and 1929.[2]

In 1929, an uprated version was introduced with a 1,795 cc (109.5 in3) engine rated at 28 kW (38 hp).[2]


A total of 9257 vehicles were produced.[4]
