Thats Awsome.....
I like it, But im not sure about that 1000Bhp.

Its interesting. Kind of a waste tho. over 13liters? Will we be supporting terrorism if we buy a car like that which will guzzle gas much more effectively than SUVs with a third the engine size?
Yes, three times more terror.

Oh, ok. Thanks for the clarification . D*** SUVS!

Well, the Cadillac Sixteen has a 13.6L V16 engine.
To save fuel, half of the cylinders will not have fuel delivered to them under normal driving conditions. So Under normal driving conditions, it will be like driving a 6.8L V8.
However, when you hit the gas, all cylinders fire up and **** gets under way very fast. Dont expect to see a 1,000hp Cadillac in the near future, but you should be expecting a 16 cylinder Cadillac in the near future, because they have gone through the trouble of building and designing the engine, and people have reacted very positively to the idea of a 16 cylinder engine in a Cadillac.
I am not sure if it was used in an actual production car or just a concept, but apparently Cadillac has used an engine where some of the cylinders shut off periodically to save fuel, and it sounds like it didnt work very well at all. I cant imagine how unreliable these engines would be. BTW, the engine was V8 which shut down 2 cylinders to become a V6.
I, personally dont like the idea of having half the cylinders shut down. I REALLY wish they would make a Full-Time V16 Cadillac.

omg, is it because they're coming up with hybrids now that they can build huge monster engine cars?!?!?!
i mean, who with the right mind would buy it? if you think about it, you'll never use the full potential of it everyday.
geez, they're nuts.
PS. even though it's cadillac, it just doesn't make sense to put that into production.

Its probably designed for the rich and also very important occasions. And just by looking at it, you instantly know they could modify the car in security aspects such as bulletproof glass.
In truth, if this was a Rolls-Royce, the Queen would probably use it. Maybe Bush will use it, who knows.

The other engine you're talking about was the 8-6-4 (not sure what it's called though). It fired all 8 cylinders at full throttle, then cut down to 6, then to 4 cylinders at cruising speed. My grandmother has one in her Cad. Eldorado Biarritz, it's a 1984. She's had the transmission replaced, but I've never heard any problems with the engine. It seems to run fine the last I rode in it, and got decent gas mileage too.
Why in the world anyone would need a 16 cylinder engine is beyond me. How many valves is that? 64? Seems a bit excessive. How many exhaust pipes will it have? 4? It's excessiveness only as a car, instead of a SUV.
Cadillacs used to look so unique. Now they're just like all the other cars on the road.

It's entirely possible. Yes, the engine has a lot of mass to fight against, but Chevy's 5.7L V8 (in the C5-R) easily gets 600HP (105HP/L). Extraploate that same ratio to the 13.6L V16 and you get 1,428HP. 1,000 even doesn't seem so hard, not that this will make it to production...
And, of course, this is one of them. I fail to see why such huge wheels are necessary on concept cars. They make the car seem overly designed, almost abstract. It also forces the company to spend even more money should the concept inspire a real car. Not only are >20" wheels unfeasable for driving, they require damned expensive tires. So if Ford really intended the Mustang to be a car headed for production, perhaps they should have designed standard-sized wheels, even if those wheels are extra chrome-y or something.

many people here have no clue about the car, and i'm not surprised.
this car gets 20mpg. it makes 1000hp from 13.6L, it's a 32v engine (2v/cylinder pushrod). the engine and the car are all aluminium, it weighs 5000lbs. projected cost is $250 000. it's a magnificent car. oh, it also runs on 87 octane un-leaded. 1000hp is pretty easy with 13.6L, it also makes 1000lb/ft of torque. i don't remember how the shutoff works, probably something like 16-12-8 or something. can't remember.
The V8-6-4 was a 6.0L V8, the problem with that car was un-reliable computers. if the computer failed, the car would be stuck on whatever cylinders it was on at the time of the failure, so if it was in 4 mode and the computer ate it you had a 4 cyl cadillac on your hands. GMs new displacement-on-demand system defaults at the maximum number or cylinders if there is a failure, computers in cars nowadays are alot more reliable anyway.

Replacement-on-demand is actually an interesting solution for large-capacity engines. I am wary, though, about the uneven load on components. What exactly do those "unused" pistons do when not in use? They just sit & oscillate, pushing nothing but air in & out?
As for the Cadillac 16, all claims are on paper only. Don't beleive anything until it's been tested, even if by Road & Track.

Theoretically...1000bhp.
But the heavy, reciprocating masses will eventually inhibit increased power due to frictional losses; it obviously won't rev as high as a race-tuned C5R V8 without some sort of rocket-booster fuel.
I say it will put out a still-impressive 600-700hp, at max rpms.
