    I was at the show yesterday and marveled at these engines in person. I think the Scuderi shows a lot of promise with the "air hybrid" concept and overall simplicity and packaging. Storing energy in compressed air is pretty cool.


    The Vengeance was actually co-developed by a cousin of a friend of mine and is darn impressive as well.


    Id really like to see both working in action.


    Ideas like these show that the IC engine will live on well into the future.

    I don't understand how the vengeance can be a replacement for the reciprocating piston engine. The problem I see here is the cam driven sliding vanes. If it's cam driven, wouldn't the forces on the wall be huge if there is even a little mismatch? Or are they not showing an internal spring? Or perhaps this is why they will be rich and I will not be.

    @philibuster: It's not a cam, it's a cam channel. Roller bearings are captured in the channel, guiding the path of the vanes and allowing precise control of their movement. You can see what I'm talking about in this image:

    The brass colored insert in the center of the assembly is the anodized aluminum guide channel. They're inventing new bits, so the nomenclature isn't quite clear.

    Hemi? Meh. And how are they implementing variable valve timing with only one camshaft riding in the block?


    That Lexus V6 could use some turbos too.

    @elwood: Do a little research. It's Chrysler's cam-in-cam technology which enables these "ancient" pushrod engines to have variable calve timing. The new Viper engine also has this bit of technology.

    I expected something from Wankelin' since you were talking about rotary flaws (one of).


    So is "Vengeance it!" going to replace the 'busa meme now that we've been exposed to this beast?

    And frankly, I just don't see it happening.

    If the vengeance works anywhere close to the way they say it will, umm yeah, small cars going VERY fast should be very easy. And yay for a rotary style motor with the potential to be reliable!

    @elwood: The seals are an improvement on the material currently in use on the Renesis rotary, and the precision of the vane control is better as well. Considering those motors are fairly durable and operate at five times the RPMs of this engine, I'd say yes, they'll be durable.

    You cannot mention "booth professionals" in your synopsis unless you post photographic evidence.

    @leavethegun-takethecannoli: Improved? Yes. Can they be improved enough to work in a production-ready engine that's going to have to work at the rated output nearly 100% of the time as a generator? I don't know.


    But for years companies like Caterpillar and Cummins have built large diesel engines for the power generation and shipping markets, and if this engine was really that competitive in terms of cost, reliability, and efficiency, they'd have way more investors throwing money at them.
