Unlike the modern bodywork, the 1,488 cc ohc four-cylinder water-cooled engine was very little changed since it had first been offered in the Opel Olympia back in 1937.
The 1,680 cc engine offering 55 hp (40 kW) at 4000 rpm, which had also first been seen in the predecessor model in 1959, was also available from the outset in the Rekord P2.
