Phil Weicker and Duncan Forster transformed their 1969 Cadillac Coupe DeVille into a fully functioning mobile hot tub, which bubbles as they drive.
The engineers transformed the vehicle, named The Carpool DeVille, based on a prototype created when they were engineering students at McMaster University, Canada.
The team bought the car for $800 and improved its heating, suspension, controls and pool plumbing in a six-year restoration.
A custom-built fiberglass tub and a converted dashboard were added to the stripped-out frame of the car - which was reinforced to take the added weight of the foaming water.
The Cadillac uses its original 472 V8 engine to heat the water in the tub to 102 degrees and a pool pump and filter were fitted into the car’s boot.
Duncan said: “It is all controlled from the driver's seat.
“The steering system is watertight and the gauges are installed behind sealed acrylic plastic.
"The marine throttle provides shift control as well as the gas and break systems.”
The pair from Los Angeles, USA. took their turbo-tub to Bonneville Speedway, Utah, in August to set the land-speed record for the world’s fastest hot tub.
However, the annual official speed-racing event was cancelled due to an excess of water on the course.
Not to be defeated – the pair decided to stage their own time-trial on a patch of dry mud and measure the speed using GPS data on smart phones.
With water streaming from the tub – the hot tub caddy reached a top speed of 50mph.
Phil said: “We were limited by course length and conditions.
“Although there are no other known contenders for the record, we expect under the correct circumstances the The Carpool DeVille ought to be able to go a lot faster.
“There’s something about combining two great passions, driving and hot-tubbing – it feels surprisingly natural.”
