What's Your Favorite Unrealized Concept Car?

My favorite unrealized concept car is this Cadillac Sixteen reviewed by Top Gear: http://www.youtube.com/watch?v=rYsrXGbBMGA

Personally for me not putting into production of this Cady is one of the biggest mistakes of GM's managers.

They can still launch it!! Late 2010 as an 2011 model...

There's no luxury sedan that looks anywhere near as nice as the Sixteen!

But we all know that the actual car would be no where as glamorous as the concept. I'm still drooling over that long hood and the beautiful engine beneath it. I wonder if the working concept was actually using all those cylinders... I mean... it couldn't just be placed on a prototype vehicle's electric motor platform because Captain Slow was driving it pretty quickly. Special effects aside, V16s are known for their balance and quietness.

Just what I was thinking. The sixteen was really sweet. That Tomahawk was outrageous!

The Lexus LF-A

Chevy volt!

Infiniti Essence

Pontiac G8 ST, basically... a Camaro with room in the trunk :P

Cadillac Sixteen - 20mpg! 1000hp. Beautiful car....

Jeep Hurricane was amazing! especially with it's 4 wheel steering. i personally am not a jeep, or chrystler, for that matter, fan, but good job on that one!

Peugeot Quasar was kinda cool back in 1984, or maybe it's only because I was a kid and easily impressed by digital screens and all these mirowave-like buttons.

As MSP6 said Peugeot I remembered the best looking concept car of all times in the car history - Peugeot 4002: http://www.youtube.com/watch?v=pe_tTJMLlTY

They made a prototype but unfortunately that was all. :(

1988 Buick Wildcat

Ford GT90, Saturn SC-T (older generation Coupe with a turbo).

Another vote for the Infiniti Essence. Build that sexy beast.

i was just looking at the ford GT90 earlier, that thing could have been the new FORD GT but they stuck with the big bulky update of the original GT40. And for the guy above, Wait till next month when the Production version of the LF-A is at the Tokyo motor show, it's no longer just a concept.

BMW CS concept! and the M12..

1997 Jeep Dakar

BMW CS

The BMW Nazca C2 and the Dodge M4S Turbo Interceptor.

From the past decade:
Infiniti Essence
Chevrolet SS Concept
Holden Efijy
Maserati Birdcage

Honda HSC

Chrysler Firepower

I hesitate to agree with two postings above.

The Cadillac Sixteen: I don't want to discount it just yet, fellas. If the guys at Cadillac are smart, which I think they are, they will use a very close design to this for the upcoming uber-luxury car that they have planned, and that we have yet to see a rendering for. I will admit that the 16 cylinder engine is NOT what the market wans at this time and would be so bespoke that it would be too expensive and plop Cadillac in very unfriendly territory. I think a twin turbo direct injection version of the LC3 "Northstar" V8 (with about 600+hp) should do the trick. I think there's hope.

The Pontiac G8 ST: That's not a concept. It's sold in Australia and New Zealand as the Holden Ute.

Cadillac Sixteen. Hands down. If Cadillac is to maintain it's momentum forward (in spite of the debacle of it's parent, GM) it will need to introduce the step up, true flagship model it currently lacks in order to stay relevant to it's market and the competition. Hopefully, we will see some renderings soon. Also, the Chrysler Chronos would have a nice one to produce. Chrysler is another company that really needs an image boost and as a limited production car it would have done the trick. Not to mention that until recently, Chryco has been the most successful of all car companies in translating a car from concept to reality with relative ease and, in most cases, with little or no loss of the concepts original style and grace.

totally.

The Cadillac sixteen looks like a modern 1985 Olds Toronado.

Lambo Cala.

1955 Lincoln Futura

Why can people have access to Cop cars (Crown Vic., Impala, Charger) but not the Original Batmoblie??
