..although I confess to having a petrol-burning sparkplug eating SEC, it's hard to argue with these numbers wrought by the mighty C111.

The world records established by the diesel-engined C 111-III:
• 100 km: 316.484 km/h100 miles: 319.835 km/h500 km: 321.860 km/h500 miles: 320.788 km/h1000 km: 318.308 km/h1000 miles: 319.091 km/h1 hour: 321.843 km/h6 hours: 317.976 km/h12 hours: 314.463 km/h

So, anyone really want a nice RUF SEC?

I have the C111 coupe book on my shelf and that was no ordinary OM617 they pulled that off with. I though the rotary engine was interesting, but what they did with the diesel was amazing. The OM617 block they used may have been fairly standard, but the head was certainly a custom job and motor was paired to a fairly large twin turbo setup with full race headers and straight through exhaust.

It must have left a cloud of black soot the folks at Supertubodiesel crave to recreate. Had they taken a 4 stator rotary engine further, I'm sure it would have had a higher top speed, but for acceleration and fuel consumption at those high speeds, the diesel was the clear winner.

Too bad the US is still so anti diesel - too many years of Ford and Chevy establishing an image of belching, foul smelling, noisy machines.

Years ago, the German Auto, Motor & Sport had a report about rotary engine inventor Felix Wankel's personal car, a Porsche 928 powered by a 500 or so hp rotary engine.
If I remember correctly, the engine was a 2 or 3 chamber.

Agreed. No ordinary OM. Still, to get somewhere near that spec, maintain driveability and preserve the range, that's what I'm shooting for.

I believe Felix had several cars, including at least one Mercedes and a Citroen, both fitted with rotary engines of his later designs. What was particularly amusing was that Mr. Wankel apparently did not drive, but enjoyed his mechanical masterpieces just the same.
