Back in 1996, a group of engineering students at McMaster University set out to build a fully functional hot tub housed in a working car. They chopped up an abandoned 1982 Chevy Malibu and converted it into The Carpool.

That group of students graduated, and began work on the Carpool DeVille. Six years later, they’re ready to take it to Bonneville Salt Flats to claim the title of “world’s fastest hot tub.”

There has been some substantial modifications to the vehicle to make the Carpool a reality. A custom fibreglass tub was built to drop into the passenger compartment, and heat exchangers were added to the stock engine system to heat the water. The plumbing and pumps for the tub reside in the truck, while the original V8 engine is up in the front. A custom air suspension system allows them to carry the massive volume of water. There’s even a marine throttle to control gas and brake from the driver’s seat in the tub.

The folks behind the Carpool DeVille ran a Kickstarter to fund their race costs. The campaign is over, but you can still check out the story and pictures of the conversion. Since it was a successful campaign, we’re looking forward to seeing this custom vehicle out on the salt flats.
