He dropped by my house early one Friday evening the day he bought it at Ackerman Buick in Ferguson, MO, picked me up, drove to a buddy’s, picked him up and we took off over the bridge into Illinois to ride all the levee roads and every other back road we could find. We had to drop off our buddy around 9 o’clock, put $1.80 in the tank and went back to Illinois! We finally returned home after midnight and somehow put over 250 miles on the car in that time!
This new category, Group A, featured very stringent homologation requirements. In order to qualify for competition, the competing model needed to be produced at least 25,000 times. Furthermore, the FIA required ten percent of these cars to be a specialty model, with another 500 allowed as “Evolution” models. If the 25,000 car limit had not yet been met, the new model had to attain a production number of at least 5000 units a year.
The remains of Ackerman Buick in beautiful Ferguson MO were finally bulldozed recently…I think they sold Hyundai or Kia out of that building most recently. I can’t say that I’ve seen an Opel of any description, in the flesh, in several decades, with the exception of an occasional Opel GT. I was a car freak as a kid, and I’m not convinced that I’ve ever seen any of the ones featured in this post…
As the war progressed, military authorities placed greater stress on the development of air-cooled engines, which they felt had more immunity to damage from weather, shellfire, and misuse. To meet this demand, Opel engineers developed an unusual variation on normal cooling for the 3.6 L truck engine. It was called "air-oil cooling", and used engine oil to take heat away from the jackets around the cylinder barrels. The heads were directly cooled by air, there being three separate aluminium finned heads, each serving two cylinders. Of this interesting engine, which developed 72 hp (54 kW; 73 PS) at 3,000 rpm on 74-octane fuel, only three examples were built.
While the Ipanema clearly succeeded the Marajó, production of the Chevette (by now in sedan form only, the hatchback having been discontinued after the 1987 model year) and of the Kadett noticeably overlapped; the newer model was placed above the old one in Chevrolet's lineup. While Chevrolet entertained the possibility of a pick-up version of the Kadett E, it never materialized.
