The car was powered by a newly developed 3,626 cc straight-six engine for which a maximum output of 75 PS (55 kW; 74 hp) was quoted, along with a claimed top speed for the standard bodied cars of 132 km/h (82 mph).[3] The engine was shared with the 3.5 ton Opel Blitz truck produced at the manufacturer's recently opened commercial vehicle plant at Brandenburg an der Havel[2] southwest of Berlin, and similar enough to the Chevrolet and Vauxhall/Bedford straight-sixes of the time that many service parts interchanged – something that was discovered when the Germans and Allies captured each other's vehicles during World War II.[citation needed]
