was watching a great little documentary on the development of the wankel engine by mazda in the 1960s. this image came up at a point where discussion shifted to japanese focus on the US market and the foreign car "invasion". i grabbed a screenshot. Great find, but it’s identified as a VW. They could have at least called it a NARP. (IMG:style_emoticons/default/biggrin.gif) |

was watching a great little documentary on the development of the wankel engine by mazda in the 1960s. IIRC Mazda bought the Wankel motor patents from NSU. I had a ‘72 RX-2 I bought used in like ‘74. It was great, loved that car! Motor had incredible power for a little boxy sedan, revved to 7,000 RPM and sounded a bit like a two-stroke (Wankels are actually). And I think I sold it to buy my first 914 in something like ‘78 or ‘79. Also fun to note that the three principal internal combustion engines were all invented by German engineers. Herr Otto, Herr Wankel and Herr Diesel… Vielen Dank, meine Herren! |

Herr Otto, Herr Wankel and Herr Diesel… Vielen Dank, meine Herren! Mazda took out a license from NSU to develope the wankel. they were given a special rate (less $) on the licensing because they agreed to limit sales of any future wankel engine cars to the asian/pacific market. other manufacturers also took out licenses from NSU. daimler (mercedes benz), GM are the ones i know about. not sure if Ford took it up, don't think so. Citroen signed a co development deal with NSU - this was known as Co-motor. the citroen deal did result in a production run of cars known as the GS Birotor. they were all bought back by citroen in an attempt to shut down warranty claims. (well nearly all - we look after a birotor here, very rare, think its the only one in aus). my mate owns an NSU RO80. he has had the car since the very early 70s (second owner). still has its original wankel engine it came with. numbers matching as they say. thats rare as well. most of them blew up before they got past 20,000 miles so run either replacement wankels or mazda transplant engines. he has always looked after his carefully. long warm up and then if he drives it no short trip. gets driven all day. its meant its only had one rebuild its entire life to get new rotor tips. rest of engine was fine and was reassembled. lot of challenges to keeping one going these days. spark plug unobtainable. but you are right. they smell like a two stroke when running. use an oil injection system to lubricate the rotor tips in the combustion chambers. the tank is separate from the sump. one of the interesting features is the sump and general engine oil does not get contaminated by general engine fuel vapors etc like conventional engines. much longer time between general oil changes compared to otto cycle engines. the NSU also has a sporto box. pretty much as per the porsche sporto box. the NSU engineers were merged with Audi by VW in the late 60s. the modern audi is in effect an extension out of the NSU. the NSU RO80s were built to a very high standard of quality. pretty much equal to a mercedes........but for the fatally flawed engine.

(IMG:style_emoticons/default/smile.gif) The NSU RO80 used forged Fuchs alloys.
The NSU Wankel went to market way too early |

You are right about the rust.
In 1970, I moved to Stuttgart and in December bought a 914/6. Hahn Porsche had 5 or 6 914/6s on their lot downtown that had been demonstrator cars given to dealers. The cars were returned to the factory for sale at about 70% of new price which was a tremendous discount for a year old Porsche with 20,000KM. I looked them over and remember seeing most of them had rust on the sheet metal under the battery. I picked one that had the color I liked instead of one without rust. Turned out not to make much difference because I sold it four years and a lot of miles later before the rust became a structural problem. Attached picture was taken in January,1971. Car had the temporary US military license plates. |

(IMG:style_emoticons/default/biggrin.gif) i think the way it went is the chief stylist at NSU eventually went on to join BMW. and......that belt line right around the car became a bmw signature. but originally an NSU thing. |
