The Opel 8/40 PS was a mid-range car that Opel built from October 1928 to September 1930 as the successor to the 7/34 PS model .

technology

The engine was a six-cylinder in - line engine with 1916 cm³ displacement, the 40 hp (29 kW) at 3600 rpm. performed. Like the previous 7/34 hp model, this enabled the car to reach a top speed of 90 km / h.

Like its predecessor, the car was available ex works as a chassis with 720 kg, as a touring car or as a sedan with 1170 kg on chassis with a 2880 mm wheelbase. There was also a roadster, a coupé and a convertible on a shorter chassis with a 2750 mm wheelbase. The Otto Kühn bodyworks continued to provide additional superstructures at the customer's request .

The engine power was passed on to the rear axle via a manual three-speed gearbox with center shift. The foot brake operated drum brakes on all four wheels via cables, while the handbrake acted on the cardan shaft .

Transition to the low bed frame

The sedans were fundamentally revised in early 1929. Their bodies became a little longer, but the wheelbase remained the same. The most important technical change, however, was the transition from the traditional loft bed frame to the low bed frame, the side members of which were directly below the axles. The main competitor of the mid-range Opel was the Adler Standard 6 , which was only equipped with a low-bed frame from 1933.

Successor and number of pieces

In 1931 the 8/40 hp was replaced by the 1.8 liter . Together with its predecessor 7/34 hp, 20,580 units were built in almost three years. This made Opel one of the largest manufacturers of mid-range cars in Germany in the 1920s.
