The engine came with a choice from two power levels. For the standard 1.0 litre engine maximum output was listed as 40 PS (29 kW) at 5,000 rpm, and in October 1963 the high compression "1.0 S-Motor" was added, sharing the 993 cc capacity of the original power unit, but offering a maximum 48 PS (35 kW) of power at 5,400 rpm. The more powerful "S-Motor" engine featured modifications to the inlet manifold, cylinders and camshaft along with a carburetor employing larger (36 mm (1.4 in) diameter than the 30 mm (1.2 in) used on the standard engine. This came with an 8.8: 1 compression ratio whereas the 40 PS (29 kW; 39 hp) engine used a compression ratio of only 7.8 : 1. Higher compression ratios for performance versions of standard engines were a growing trend in West Germany in the 1960s, led by Opel and Ford, and made possible by the growing availability of higher octane "Super" grade fuel at filling stations.
After the uplifting podium at the Hockenheimring, Opel fell right back into the deep hole they were working so hard to crawl out of. For the next four rounds and eight races, the team couldn’t reach further than 5th place, and experienced numerous mechanical failures. The trips to the Nurburgring, Mugello, back to the Nurburgring and the Norisring all proved fruitless for the outfit.
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…
The Kadett A (above) finally appeared in 1962, and was a classic GM/Opel effort: highly pragmatic, conventional in every respect, reasonably stylish for its time, and designed to deliver a good bang for the buck. In just about every way possible, it was the antithesis of the VW: front-engine rwd, a rather tinny but roomy body, highly tossable but with a primitive suspension and ride, a very roomy trunk, and excellent visibility as well as economy. Oh, and a proper heater even! Its little 987 cc OHV four made 40 net/46 gross hp, six more than the VW 1200. Its trim fighting weight of 1475 lbs (670 kg), some two hundred pounds less than the VW, showed in both its acceleration and body integrity.
