Corvette Killer: 1964 Pontiac XP-833 Banshee Prototype

Update 4/20/2020 – After more than three years since we featured it, this Banshee prototype is still on the market. The dealer has now listed an asking price of $750k here on their site. Thanks go to Rocco B for sharing the tip!

From 12/27/2017 – It’s the holiday season again, and I know we’re all wrestling with the age-old gift-giving dilemma of what to give the gal or guy who has it all. I’ve got you covered! You get her or him something no one else can have: the only Pontiac XP-833 Banshee coupe in existence. This truly lovely little piece of GM history is now available—on craigslist, of all places, as well as Hemmings and other such reputable outlets—from a dealer in Milford, Connecticut (archived ad). Price? Well, if you have to ask….

One of several sports car concepts floated by various GM divisions in the mid-1960s—others included the Corvair Monza GT, the Opel Experimental GT, and the two Corvette Mako Sharks—you can especially see how the Banshee’s rear end styling influenced the 1970 Firebird. In addition to this six-cylinder coupe, there was also a fully-functional V8 roadster built, which also still exists today. Aside from the Opel, which was eventually built on Kadett economy car bones, none of the non-Corvette concepts reached production, largely to protect the Corvette’s standing as king of the GM hill. While then-Pontiac boss John Z. DeLorean referred to the Banshee as a “Mustang fighter,” its lightweight fiberglass construction gave it Corvette-threatening performance.

DeLorean had every intention of putting the Banshee into production, and it shows—although the rearward-hinged canopy roof is pure show car fantasy, this is a remarkably well-finished little coupe. Still, prototype details, like the Cadillac seat belt buckles, remain. When the project was canceled, the Banshees were slated to be destroyed, but luckily both were preserved by, and eventually sold to, Pontiac employees. The coupe remained in the hands of the original owner until 2006, at which point it was sold at Barrett-Jackson for $214,500; as recently as 2015, it was estimated that it would fetch $600-650,000, although it didn’t sell at the high bid of $390,000.

The running condition of the 230-cubic inch Pontiac OHC inline six is not disclosed (it was said to run and drive at the time of the 2015 auction), although it shows just under 1,500 miles on the odometer, so it certainly hasn’t been used hard. Given that this is essentially a priceless car, it’s not as if you’d be driving it to Safeway anyway, but it’s nice to know that, with a production-car engine, any repairs that would be needed under the hood would be easily doable.

What a neat little car this would have been! While it’s a bummer to know that the Banshee was never made available to average schmucks like you and me, it’s nice that at least one lucky person at a time gets to experience what might have been. If you were the one who had it all, what one-of-none dream car would you like to own?

    Beautiful car and concept. I’ve read of them but never knew any escaped the crusher. It’s sure to end up in some museum – either public or private.
    Here’s hoping it ends up somewhere that people can see and appreciate it.

    A few years back there was a coupe at the Crawford Museum in Cleveland. I wondered which was first, this car, or the mako shark 2, or the manta ray. I don’t want to give creds for the ’68 Corvette style to DeLorean for some reason .

      GM executives instructed DeLorean to cease further development in 1964. In a move loaded with irony, a memo to GM’s head of design, Bill Mitchell, dated September 10, 1965, instructed Mitchell to have his staff update the XP-833 exterior clay and interior bucks “reflecting a Chevrolet design for the two-passenger version coupe.” And so it was that the XP-833 project was revised to become the C3 Corvette against which it had been forbidden from competing. The Mako Shark II which became the C3 Corvette was introduced by Bill Mitchell as “his” design in 1965. One year after DeLorean introduced his Banshee concept. Who copied whom? Typical corporate BS. The C3 Corvette began as a Pontiac.

    There were actually 3 of these cars built (well 2 1/2). A 3rd body (which I owned back in the 1980s) was constructed but never completed. Have one very poor image of it hanging in my garage. Sold it to a Pontiac engineer who had plans on completing it but I never heard the outcome.

    What does it look like with the top off?

    There is no trunk lid and the panel lines suggest that the roof comes off to the rear of the car??? That makes no sense and would look really odd as the styling on the rear of the car would not be smooth.

    I’ve looked in a number of places for pictures, and although I can find pics of the interior with the top off I have not found any shots of the car either in profile or from rear 3/4 view that would show what it looks like topless.

      The top on this one doesn’t actually come off; instead of a trunklid, the entire roof section is hinged at the rear. I’m not sure what the practical advantage of this is, although I imagine it would make getting into such a low car easier.

    DeLorean made a habit of tweaking his superiors, interesting guy. Pontiac had originally planned to call their Camaro equivalent the “Banshee” until someone pointed out that Banshee means “Bird of Death”.

    Killer car. C2 Vette in the front with a hint of C3ness. Firebird in the back. I can see why GM killed the project. The Banshee would have wrecked the Stingray’s dominance in the 2 seater market. DeLorean may have said “Mustang fighter” but I’m sure he was thinking “Stingray crusher.”

    I think ya’ll are missing something here. This was a concept car. That means Delorean would have had a lot more latitude in his design options as opposed to his final production models. GM if approving it for production instead of nixing it would probably have said cool design, but your gonna have to do something about that rear hinged roof idea. He then would have eliminated it and let it be more corvette like and solid. He knew how to work GM pretty well most of the time. This time though he didn’t win in so far as getting it into production. I think he just got fed up with them and that is why he produced his own car eventually. You can only have your ideas rejected so many times before you just up and leave. Especially when they are great design ideas. This was really one of his better inspired ideas that should have floated no problem. He used existing parts for 95% of the prototype, just ad a little bit of retooling and they could have been cranking them out and making money. This is actually a huge benefit as opposed to coming up with a total and complete redesign or introducing a brand new model altogether that would have required far more start up costs. It would be interesting to know who the actual people were that said no to the idea so we could tell them if they were still alive that they just blew it that time.

    What happened to this car? Well GM brass made sure it became the C3 corvette. To this day the Corvette looks more like the Banshee than the original Corvette design. DeLorean doesn’t get credit for this and so many of his many other influences on the automotive industry because of the problems and controversy with the DMC-12 that tarnished his legacy.

    The name “Banshee” was tossed around GM, taken from a WWII fighter plane (as Ford did with Mustang). Typical for a large organization, no one looked up the word in the dictionary which has a constant theme: messenger of death — which would not have played well in sales rooms!

    Fascinating.
    Has me wondering why the B-J sale price was so low. Car investors are a funny lot, obviously so influenced by each other as to have a herd mentality. If it had been set up with a V-8, would someone want it more? Since the convertible built has the extra cylinders, is it bigger $?
    So Lennie Napoli sits on the Banshee, figuring that someday, someone will pay his price for what is arguably one of the most historic prototype built cars in the lineage of auto-making in the USA.
    I can’t say that he is wrong for doing that.

    BUT: If he really wants to sell it, there is marketing to be done, and that takes money. Display at Amelia Island, Monterey, and others. And be certain that it could be driven around on the grounds of the shows.

    A quick follow up to my earlier post.

    First, how did an image of my story end up as an image above my text? Intervention on Barn Find’s part? If so, thank you. I don’t see any way to attach photos to a post. What am I missing Jesse?

    Second, I was standing with the Killen Family when the car sold and they were as shocked at the hammer price as I was. I thought the car sold for one-fifth my expectations. As I mentioned in my Musclecar enthusiast column, Mopar B-body Hemi clones sold for more that weekend.

    I spoke with Lenny Napoli this morning. We talked 14 years ago when he bought the car. At the time, I couldn’t get a magazine interested in a detailed feature on the car. I think this time, I might be more successful.

    I am going look through my files to see what other photos I took of the car back in 2006. If there’s interest here, I might post a few.

    This is, by any measurement standard, a very significant car on so many levels. I have written about similar one-offs, like the Jaguar Pirana Bertone Coupe which, after a major refurbishment, sold for more than $400K last Summer. In my opinion, this car is worth more. How much? I simply don’t know.

    Here’s a link about what I wrote a while back on the Pirana I mentioned above. I think it serves as something of a benchmark for the Banshee, which is a real GM concept from the Golden Age of GM Design.

    Well, the conversation here seems to be going on and on. I’ll say that this is an interesting concept car, but really just that. Yes, the design is similar to the C3 corvette, but the lines are not yet as clean. There are elements of Riviera, tail lights from the ’66 GTO, seatbelts from Cadillac and door handles that became common a few years after this car was produced. A design exercise. Beautiful? Um….no not really when compared to, say, an e-type, the orignal C3 concept or even a C2 or C3 Corvette. Worth $750k? To the right person, maybe, but apparently that person has not come forward yet. This car will spend the rest of it’s life in a garage or on a showroom floor or, maybe, a museum…technically, I guess it belongs in the Corvette museum.
