WOW../ Nice pics..

Damm, that **** is sweet. Well done

I may just be slow today, but what is NSU? And what are these engines for?

Excellent.

NSU is the place Wankle worked for isnt it? That's why it says NSU on our engines!



They made the first rotary powered car

ahhh, makes sense. But those pics look not too old, so what are they pumping out 3 rotors for? And what is that blank tank on top of one, with what looks like the drive shaft coming out the side of a transmission? What vehicle would that be for?



I'm just curious, any ideas?

those last few look like mercedes to me.



holy carp! the 4 rotor has mechanical fuel injection, and look where the nozzles are!

awesome pics. Nice find Cales.

Guys, we all have NSU & its #1 employee (Felix Wankel) to thank for the rotary engine. NSU produced the first Wankel/rotary engines & the first rotary powered car was an NSU Spider from 1963. (Single rotor)



The 2nd NSU car was the ill fated Ro80 from 1967. Powered by a 117hp 1lt twin rotor engine, they would have been the car of the century had NSU waited another 2 years to sort out reliability issues. Feeling the pressure from investors, rival license holders (Mazda) & the need to get a return on the never ending expenditure, the Ro80 was released prematurily in 1967.



By 1969, the rot had set in & NSU fell into the waiting arms of Audi. Via Audi, the VW group allowed further development of the engine & there was talk of a 3 rotor powered Audi-100 for 1977. History shows us they went for the 5-cyl engine instead.



The 4-rotor pics are from the Mercedes camp back in 1970 when they played with the rotary engine. They used that in their C-111 concept car.
