We are all "experts" in our own cars so may I start with this ...
This rebuild by MAT in Finland is right up the category "Hardcore Car Porn" for petrolheads ... 1,500+ pictures ...
A 305 bhp 2.1L 10V 5-cylinder engine.
Audi entered rallying as course car (Number 0) in the 1980 Algarve rallye (Portugal) driven by Hannu Mikkola. The job of the course car is to verify the course is driveable. Mikkola finished over 25 minutes faster than the race winner.
In the 1981 Jänner Rally (Austria) driver Franz Wittmann secured Audi's first unofficial WRC win. Second place car came in just over 20 minutes later.
The Audi Quattro was the first rally car to introduce both four-wheel drive (quattro) AND turbo. From that date no front- or rear wheel drive car won the the WRC title.
The original plan was to make 220 cars to be sold to the public in order to become homologated. Audi was overwhelmed by the demand and a total of 11.452 units were produced from 1980 to 1991, of which just 664 were sold in the US and an additional 99 in Canada. Engine was upgraded 2 times in the process from 200 bhp 2.1L 10V K-Jet CIS over 200 bhp 2.2L 10V Motronic EFI to 220 bhp 2.2L 20V Motronic EFI.
The production line in Ingolstadt - 46 senior workers built the cars by hand with the help of Baur Karosserie- und Fahrzeugbau GmbH in Stuttgart. Single shift 06:00 to 14:00, 5 day working week. Some time during 1985 engineers discovered that 8" rims could be fitted without problems so they changed the drawings to match the car
Once completed, each vehicle went through a test programme. The engine went through its own test cycle, and the suspension was electronically checked. Then it was run up to 160km/h on a test stand and driven for 60km on public roads around Ingolstadt - first on ordinary roads and then on the Autobahn, with a rev limit of 4000rpm or 185km/h. Then it went around an Audi test track to check the suspension. On each trip two stops were made to check fluid levels. Finally a rain test showered the car with 3500 litres of water for ten minutes.
Todays prices for a prestine and untouched series 1 "four eyes" is about 40-50.000 Euro. A new car in 1980 was 50.000 DM which roughly amounts to 56.000 Euro in todays money.
When Audi formed quattro GmbH (now Audi Sport GmbH) October 1983 they also ruled that from that date "quattro" was to be written with a lowercase "q". My car was built 1981 (1982 model) so I have the users manual with the uppercase "Q"'s
Now the largely unknown tidbit about Audi is that a Dane, Jörgen Skafte Rasmussen, besides founding DKW he also also founded Audiwerke AG Zwickau for building his DKW cars. Long story cut short ... In 1938 Adolf Hitler arranged to pay Jörgen Skafte Rasmussen a kompensation equal to 5,3 million Euro and deported him back to Denmark.
Ein gleichmäßiger Zündabstand von 144 Grad bei einem Kurbelwellenkröpfungsversatz von 72 Grad samt Zündfolge 1-2-4-5-3 nehmen dem Fünfzylinder auch bei hohen Drehzahlen die Geburtsfehler ungünstiger Massenmomente und taumelnden Schwingungsverhaltens. Sie geben ihm jenen sonoren Stakkato-Klang, der Gänsehaut erzeugt. Man nennt diesen Klang auch quattrophonie.
