M she already knows from electronic fuel injection and the Control units for automatic transmissions.

ITT, formerly Teves, introduces them, Bosch and Ate have also developed electronic locking regulators that are ready for practical use.

IAA 1969: Computers begin their triumphal march in automotive engineering

And the future for them Computer looks rosy, as auto motor und sport predicts: “Other computer developments deal with automatic distance control, with fading in and out and even reading traffic signs. To what extent the practical advantages justify the effort remains to be seen. There is no question, however, that the possibilities of computer technology will in future be used more in the car than before. ”

Mercedes stand besieged for days because of the C 111

The Mercedes stand is at the 1969 IAA besieged for days. The reason is the C111 with a body made of fiberglass. A super sports car with 280 hp - and, more importantly, powered by a three-disc Wankel engine with direct injection. The C111 accelerates to 100 km /h in five seconds, and it's over at 260 km /h. That sounds good, but others can do it just as well or better.

The media and public interest alone can hardly compensate for the several million marks that devoured the development of the racer. There is a large party at Mercedes that reject all Wankel ambitions and see the classic reciprocating engine as the best choice for future success. The C111 was later also a test vehicle for diesel engines and turbochargers. In 1970 the C111-II comes with a four-disc Wankel engine and around 375 hp. Now 290 km /h are possible.

VW 181 - the car of the hippie generation

The universal -VW is designed as a DKW Munga successor, i.e. actually for military use. But a completely different target group is now extremely keen on him: the alternative scene and above all the American hippies. It's cheap, gets through everywhere, thanks to the foldable windshield, offers more outdoor fun than almost any other vehicle and has space for six or more passengers. In bright colors with large flowersbrushed on with the 181, one is “dressed” very well at anti-war demonstrations. VW also jumps on the train. Press photos show the military vehicle occupied by young people playing the guitar. The four-wheeler designed with the ruler can compete with the buggies as a fun mobile.

Audi 100 Coupé - most American Audi of all time

Audi is showing the 100 as a coupé at the 1969 IAA.

The Audi 100 sells brilliantly, much better than the VW 411, and so there are two new body variants at the IAA 1969: the two-door 100 and a real coupé. The coupé is particularly appealing thanks to its sporty appearance and American lines: hip bend, typical fastback rear end with ventilation slots and ten centimeters lower than the sedan. Propulsion is provided by the four-cylinder, expanded by 70 ccm, which now delivers 115 hp with a Solex register carburetor.

IAA 1969: Opel CD with a bitter future

Opel shows the study CD Commodore base. The vehicle is not given any chance of series production - we already know that from the GT - but Opel remains consistent with the CD. Erich Bitter took up the topic a little later and built 395 copies of the large coupé with the large-scale technology from 1973 to 1979.
