Hot Tub Cadillac
It is what it looks like, if what it looks like is a nice way to take a drive in a hot tub. This is the dream of Carpool DeVille: That a fully functional hot tub can be wed with an appropriately modified sedan to achieve a thrilling, seamless marriage of these two great American pastimes.
In 2018, we sold the Carpool DeVille at the famous Barrett Jackson Auction. However, before we let it go, we had all sorts of fun in it, and even set a Guinness World Record ("Fastest Motorized Hot Tub" Still stands). We invite you to explore this website in order to see what we built, and share in our adventures with it.
This idea originated in 1996 with a prototype built into an abandoned '82 Chevy Malibu. Concepts like marine-throttle control, tub-water re-coup of engine waste heat and DC/AC inversion to run a spa pump out of the trunk were all tested to a remarkable success, while notes were taken about deficiencies in suspension and the water lost to sloshing. A full decade of fix-and-fill hot-tub-car-parties with this original carpool provided all the R&D that would be required.
In 2008, a selection was made out of a '69 Cadillac DeVille. 1969 may well have been Detroit's (ahem) high-water mark for automotive design: The absolute pinnacle of American auto-largess, when the public craved every larger cars, and the cars required ever-larger engines. This hot tub is founded on extra steel and lots of power.
After seven years of design and construction, the Carpool DeVille is ready to hit the road - and the race track.
