Very, very easy to get these cars confused . . . but in the final analysis, the car in the quiz is not a Dual Motors product. It is the Dodge Firebomb, built as a Chrysler Corporation show car by Ghia. No Dual Motors connection at all, other than being shown by Gene Cassarole to attract investors to his new Dual Motors company. It was shown to demonstrate approximately what the forthcoming Dual Ghia might look like - and it did turn out to be very simlar, although many details and dimensions differed.
If the car in the quiz has been "identified as a Dual Motors", it has been identified incorrectly.
I intended my puzzle not to be the original Dodge nor a Dual-Ghia but this Dual-Motors Corporation Firebomb, although I suspect they probably never actually made any cars and used a picture of the Dodge Firebomb in their publicity? Is that right?
Yes, you have it exactly. There is no such thing as a Dual-Motors Corporation Firebomb. They built Dual Ghias, which this car is not. The advertisement you posted is part of the on-going problem . . . and it is entirely incorrect. Dual Motors did not build the car in that ad, and it was not built for them. It was, again, simply "borrowed" by Gene Cassarole so he would have something to show investors. There was more than one Dodge Firebomb built by Ghia, I can only assume Gene Cassarol bought one of them to use as an inspiration for his own later car. For my money, Richard Cuyler got it correct in the first place by identifying the car as the Dodge Firebomb built by Ghia . . . because that's exactly what it is. However, as always, your quiz, your call.
Just a quick (but important) aside here . . . I am in no way impugning Carnut’s intentions or choice of puzzle car. His quizzes have added a lot to what continues to make this site so much fun. This isn’t the first puzzle that has been incorrectly “solved”, and won’t be the last. If you want to get bad results, start with bad information – there’s a lot of it out there. Even some of the museums that display these cars have them incorrectly labeled, or have signs that perpetuate incorrect information. It’s really, really bad form to whip out a black magic marker and correct their signage – also a good way to get banned from a museum for life, and rightly so. I hope my efforts to “get the story right” on this car will not be seen as a criticism or attack. I certainly don’t mean it that way, and I hope Carnut will take my comments in the spirit in which they are intended: an honest effort to get the facts straight. Again, I appreciate the effort he makes to post these puzzles for all of us to enjoy, and if anything I have posted offends, I apologize.
