History and technology

The 1-liter was only built in 1933 as an essentially identical economy version of the 1.2-liter .

The car was built on the U-profile pressed steel frame of the 1.2 liter with a short wheelbase. The chassis, front and rear rigid axles on semi-elliptical leaf springs with hydraulic shock absorbers and the braking system with cable-operated drum brakes all around came from this.

Like the 1.2-liter, the 1-liter also had a single-disk dry clutch, a gearbox with three instead of four gears as in the 1.2-liter, and manual transmission. The differential was on the rear axle.

The 1.0-liter four-cylinder in - line engine of this model was new . The stroke of the 1.2 liter engine was reduced from 90 mm to 75 mm while the bore of 65 mm remained the same. The engine thus had a cubic capacity of 989 cm³. It was equipped with side-mounted valves . The mixture was supplied from a single carburetor. The compression was increased to 6: 1, so it made 18 hp (13.3 kW) and accelerated the car to up to 75 km / h.

The 1-liter was available as a two-door sedan and a four-seater convertible. As early as the end of 1933, production was stopped after 5,600 copies. The small four-cylinder models found a successor in the P4 in 1935 .
