The article has larger photos now. Now that im not using dial-up anymore ...

and you can click each photo to show even larger

Yes, Nissan did large-scale development of the Rotary. They got a license from NSU in 1970 October. In late 1972 they had journalist drive the cars. They were planning on mass production of 3000 cars/month. The S10 Silvia was designed for the space-age motor.

Then the performance car market crashed (insurance and economy -- it killed the US muscle car too). In late 1974 they canceled the project, leaving Mazda and GM as the only automakers still working on the rotary


Found this article from December 1972 Driver magazine "First Test Drive Nissan Rotary"

120 horsepower @ 6000 rpm
116 ft lbs torque
[that put it in the territory of the Skyline]

Looks like a stock PB110 (except for the engine)

Nissan officials said the company has developed rotary engines to be used for its vehicles under a license obtained from Audi NSU Auto Union Ag., of West Germany, in 1970.

They said the new rotary engine autos, "Sunny"-type passenger cars, will be shown at the Tokyo motor show this fall and put on sale by fall 1973.

A total what might have been. 1600lb car with 120hp in the 79s would have been a rocket.

I like the first pic with the EXA rear end of that prototype ESP-II??

As for rotary, got priced factory parts to rebuild a 13b-rew at over 30,000usd!!!

All that surface area of the rotary lost as heat will never make it as a future
engine and when a 1jz can do double the hp with 9000rpm at a third of the cost
no one needs a rotary engine in anything.

An A12 with a turbo would have been cheaper and easier than Nissan developing that rotary. Even an A16 special edition with 120hp would have fetch 100k+ usd today

That reminds me, back in 2004 it cost less to rebuild a hot 13B than it cost to build a hot piston engine. Racing Beat at the time supplied the parts. When I looked a few years ago, Racing Beat was out of business and prices had skyrocketed


This pic?

The white car in lower right corner is the Toyota ESV-II, shown at the 1972 Tokyo Motor Show

Sunny Rotary pic there was at the 1973 Tokyo Motor Show. At that show they had the Datsun's ESV which was a car of the future -- it looked a lot like the 1976 Datsun 810, but the grill looked like a 1978 Celica!
