The Opel Commodore is a vehicle from Adam Opel AG positioned in the upper middle class . The Commodore was derived from the Rekord C and from August 1966 replaced the Rekord 6, the "intermediate model" Rekord B with a six-cylinder that was built for just under a year . Production of the successor Commodore B began in December 1971.
The Opel Commodore A , available from spring 1967, was launched on the market as an upgraded sister model of the Opel Rekord C (with four-cylinder engines) and was available as a two- and four-door notchback sedan and a two-door coupé. A luxurious combination model called "Voyage" was only presented as a study, but did not make it into the regular sales program. The coupé was converted into a convertible by Karl Deutsch GmbH , among others .
The characteristic of this series were the Opel CIH engines introduced with the Opel Rekord B , in which the overhead camshaft, driven by a duplex roller chain and laterally next to the valves, actuates the hanging valves via short hollow tappets and rocker arms. These engines were used in almost all larger Opel models up to the 1990s: in the Omega A (2.4i / 2.6i / 3.0i), Senator B (3.0i / 3.0i 24V) and most recently in the Frontera .
Engine variants
Six variants were available as motors:
2.2 - 95 PS (70 kW)
2.5S - 115 PS (85 kW), from 1969: 120 PS (88 kW)
2.5H - 130 PS (96 kW) (GS)
from 1970 additionally:
2.5E - 150 PS (110 kW) (GS / E)
2.8H - 145 PS (107 kW) (GS / 2.8)
The smallest engine with 95 hp had a displacement of 2.2 liters and was only built in small numbers. The "Rekord 6" had it before, which was in a small series a year before the introduction of the Commodore models.
Initially available were the 2.5 S with 115 HP (from August 1969 with 120 HP) and the more powerful Commodore GS model with the 2.5 H (130 HP) engine. The top model GS / E , available from February 1970, was fitted with a 2.5-liter engine with electronic fuel injection ( Bosch D-Jetronic ) that developed 150 hp. Upon request, the vehicle was also delivered with a three-speed automatic transmission.
From April 1970 to September 1971 there was also a small number of the GS / 2.8 model with a displacement of 2.8 liters and 145 hp. A total of 156,467 copies of the Commodore A were produced between January 1967 and December 1971, of which 72,597 were for the four-door sedan, 70,333 for the coupé and 13,537 for the two-door sedan.
