The Opel 34/65 PS was a luxury class car that Adam Opel KG built from 1910 to 1913 as the successor to the 35/60 PS model .

History and technology

The 34/65 PS was no longer the most powerful model in the Opel model range at the time; although its engine made 5 hp more. It was accompanied by the more powerful 28/70 hp in the year it was released . In essence, only the piston diameter of the engine was reduced by 10 mm compared to the previous model and the piston stroke increased by 20 mm. This resulted in a 5 hp higher performance. The wheelbase of the only available chassis has been extended by 330 mm.

The 34/65 PS had a side-controlled four - cylinder block engine with T-head and 8760 cm³ displacement (bore × stroke = 130 × 165 mm), which made 65 PS (48 kW) at 1600 / min. The engine was water-cooled; a centrifugal pump provided the cooling water. The engine power was transmitted to the rear axle via a metal cone clutch, a manual four-speed gearbox and a cardan shaft . The maximum speed is given as 90 km / h.

The sheet steel U-profile frame was now available with a wheelbase of 3570 mm. The two rigid axles were suspended from it on semi-elliptical longitudinal leaf springs. 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.

Like its predecessor, the car was available as a four-seater double phaeton , a four-door Pullman limousine or a landaulet . However, the cars had become much cheaper - although they were more powerful and larger than their predecessors. The cheapest variant (double phaeton) only cost 15,000 RM.

In 1907 , the Opel works driver Carl Jörns with a modified 34/65 HP came third in the Kaiserpreis race in Taunus behind Felice Nazzaro ( Fiat ) and Lucien Hautvast ( Pipe ). This success earned Opel the title of imperial court supplier for automobiles as the manufacturer of the best-placed German vehicle .

Production of the 34/65 hp was stopped in 1913. The successor in the following year was the significantly more powerful 34/80 hp .
