Opel 40/100 PS

The Opel 40/100 PS was a upper-class car that Adam Opel KG built from 1912 to 1916. It was the largest and most luxurious model the maker offered before the First World War, with a propeller shaft in an oil bath and a front subframe to carry the engine. Its four-cylinder side-valve block engine with a 140 mm bore and 165 mm stroke displaced 10,160 cc and produced 100 PS (74 kW) at 1,300 rpm. Power passed through a leather cone clutch, a manual 4-speed gearbox and a propeller shaft to the rear axle, and the car reached a top speed of 125 km/h. It was offered as a six-seat double phaeton, a six-seat torpedo, a four-door Pullman saloon or a landaulet. The double phaeton, the cheapest body, cost 18,000 reichsmarks. Production ended at the end of 1916 without a successor.
