Opel 10/18 PS

The Opel 10/18 PS was a upper-class car that Adam Opel KG built from 1907 to early 1910 as the successor of the 12/14 PS and the 14 PS. Its size lay between those of its two predecessors. Its four-cylinder side-valve engine cast as two blocks displaced 2,545 cc and produced 18 PS (13.3 kW) at 1,600 rpm. Power passed through a metal cone clutch, a manual 3-speed gearbox and a propeller shaft to the rear axle. It was offered as a four-seat double phaeton, a four-seat touring car, a four-door saloon, a landaulet or a two-door coupe. The double phaeton, the cheapest body, cost 8,500 reichsmarks. It was built until early 1910 and then replaced by the slightly larger 10/20 PS.
