Duesenburg Custom Coach has delayed the launch of its Duesenberg II Torpedo Coupe. Based on the Mercedes CL500, the Duesenberg II Torpedo Coupe was originally slated for an August introduction but is now expected to bow in mid-2008. No official reason has been given for the delay.
When the Torpedo finally does break cover, it will be powered by a conventional engine as well as a new engine-technology known as Cylindrical Engine Model. The CEM engine –which was designed by E.P. Industries — uses a rotating 12-cylinder engine that produces 300 horsepower yet can achieve 70 mpg.
According to Hemmings, Duesenburg is also planning to launch a Murphy Roadster. Powered by a V10 engine, the Roadster will ride on a Ford chassis. The Murphy Roadster is scheduled for a 2008 release and will be available exclusively at Old Yesterday Classic Autos in San Diego.

There is something in it from ’70s Monte Carlo. Front and rear fenders. It was a beautiful car.

Vomit. I embrace the resurgence of coach building, but that looks like a cousin of the Stutz Bearcat from the late 70s.

What is a “rotating 12-cylinder engine”?

WTF is a rotating 12-cyl? IS it anything like a Wenkel?
It’s pretty ugly though – I’d rather just take the Benz CL500.

One possible reason.. when they hung thir fabricated fasciae to the largely M-B CL body, it ended up looking nothing like the drawing?

A new Duesenberg is never, never, never, never, ever going to happen. And that’s probably a good thing, because you simply cannot re-create Duesenberg. Its just foolish to try.

By the way, if you like Duesenberg the way I like Duesenberg, you might find the headstones of Fred and August interesting.

The release of my new Wills-St. Claire “resurection Mark II” model has been postponed until I can find some new sucke…..er, investors who are blind AND rich!
Official reason for delay? No money!!!!
The illus. looks like it has a little too much camber…..could be good for corner carving…..oh, wait, it’s a DUESEY!!! you don’t drive them hard!

I’m more interested in the engine. Their are no relevant hits on line for this type of engine, even as a hypothetical. But it sounds cool. Now if it were real…

CEM is Cylindrical Energy Module. It is a type of rotary engine. Therefore the “12 cylinders” is misleading to those who don’t know what a CEM is. It does not have pistons and a crankshaft like a traditional internal combustion engine but rather two sleeves with 12 holes each drilled into them (sort of like a large revolver cylinder. ya know, the dirty harry guns). Then there is one rod per cylinder, the piston if you will. One cylinder is the compression side and one cylinder is the combustion side. A fixed cam controls the movement of the pistons. The pistons and cylinder heads are the only things that move in the engine. The cylinder heads are simply a set of two round plates of metal which have two holes drilled into them. They are set to align with a cylinder to intake and a cylinder to exhaust. There are no valves since it simply uses holes and pulses from the piston for the intake and exhaust. There are only seven moving parts in the engine so it is much lighter and much more reliable than a common piston engine. It is a very simple design when you get right down to it. They are generally built with a bore equal to the stroke. Anyhow, this is a brilliant design currently in the prototype stages. There are working models right now but none are tested and approved for production usage.

Sorry guys. I gotta make a correction. There are only 6 holes per sleeve and with two sleeves, that makes for 12 cylinders.

Jaguar XJ-S,
Thanks. This looks absolutely brilliant. If it can deliver like this (300Hp and 70Mpg) then we could be hearing more about the engine in the future from other makers.
I’d laugh if Mazda opted for this engine for their next RX. It looks simple enough that they could make it work.
But it need some attention to the piston pins. Those look like they could wear out pretty fast. They need to be rollers or on rollers.
There are other alternative engines out there as well, like the “Star Rotor”. But this CEM looks actually more promising. The Star Rotor is basically a heat pump using heated air to spin a “compressor”. It has been tested so far at 150 hp and 60Mpg. Not nearly as impressive as the CEM. Plus I can see people in cooler regions being put off by an engine that seems like it would need time to heat up before it can run well. I mean more than a conventional ICE. I’m still a fan of the Star Rotor, for it potential, but the CEM has me as well now.
Still Duesenberg has a nice looking car on the drawing board. But As of right now, I’m want that engine!
And I also agree. It looks like a Hot Wheels car. That’s not a bad thing, but dude that’s just wicked.

I think the technology exists to make the pistons last for a good long while. Simply milling every part .0005″ small and coating with a very hard ceramic plating would greatly increase the engine’s lifetime. I’m sure this is something that the engine manufacturers will take into consideration. I don’t think rollers are the answer to durability. Something like ceramics are already proven by various racing teams to take a solid engine and make it bullet proof. Plus, the ceramics help to keep heat down. And Rotman, if the engine doesn’t matter, get a baby seal skin sofa and quit complaining about it.

It’s just a hoot to have a car upstaged by the engine, isn’t it?
I know engineers are not dummies, so they should answer durability questions pretty quickly. Maybe I’m just not used to seeing such a wonderfully simple engine design. Even a Wankel Rotary Engine doesn’t look quite this simple and elegant.
So with that out of the way, one would hope that this engine design is found in more than just hyper expensive cars. This engine is smaller than a dirt bike engine and as powerful as most V6s and V8s on the market.
I would love to see this in a compact car. Or better yet, a muscle car. Drop that huge heavy engine for this tiny, lightweight motor and watch that car lose almost half a ton.

I looked again. EP Industries does use rollers on the piston pins. They appear to be made of metal running along their “wave” track. Like a cam shaft a thin sheen of motor oil may be all that is needed.
I still like the Ceramic coating notion, but that could needless raise the cost. But given just how simple this engine is, a child with a few wrenches could put this together in an hour, the sheer lack of parts by number quantity, and the simplicity of those parts means that ceramics could be used, if sparingly, to improve engine durability.

Actually, Blakkarr, this engine is such a simple design, I think any home mechanic with a horizontal mill, a lathe, and a fair level of skill could build one. The cam would take some careful planning could be fabricated by hand. This motor looks so simple and cost effective to build, I don’t think it would be a huge waste of money to go ahead and ceramic coat at least the major friction surfaces. Regardless, I continue to be intrigued with this design as several of us appear to be. We do have to give credit to Duesenberg for seeing a promising design and having the guts to produce it. I would love to see one of these cars. I am curious as to how this motor would sound. Also, this thing should be able to run off whatever flammable liquid you throw at it. Assuming that the fuel pump, injectors, and hoses could handle the acidity, this would be a fantastic flex fuel platform. This design just has so many possibilities.
