The Opel 28/70 PS was an automobile of the upper class , which the Adam Opel KG only in 1910 as a successor to the model 30/50 PS built.

History and technology

The 28/70 hp was the most powerful model in the Opel model range at that time, even more powerful than the contemporary 34/65 hp , albeit with a smaller displacement.

The 28/70 hp had a side-controlled four - cylinder block engine with a displacement of 7270 cm³ (bore × stroke = 115 mm × 175 mm), the 70 hp (51 kW) at 1600 rpm. performed. The engine was water-cooled; a centrifugal pump provided the cooling water. The engine power was transmitted to the rear axle via a leather cone clutch, a manual four-speed gearbox and a cardan shaft . This enabled the car to reach a top speed of 90 km / h.

The two rigid axles were suspended from semi-elliptical longitudinal leaf springs on the sheet steel U-profile frame. The service brake was an internal shoe brake that acted on the output shaft of the gearbox. The handbrake was designed as a drum brake on the rear wheels.

The car was available as a four-seater double phaeton , as a four-door Pullman limousine or as a landaulet . The cheapest variant (double phaeton) cost 15,000 RM.

Production of the 28/70 hp was stopped at the end of 1910. The successor was the 29/70 hp , which was only built from 1914 .
