These pictures show the €1 million (£750,000) prototype, which can dive to a depth of 10m, in action off the coast of Florida.
It was the brainchild of concept car designer Frank Rinderknecht, 52, who said: “For three decades I have tried to imagine how it might be possible to build a car that can fly under water. Now we have made this dream come true.”
He added: “Everybody knows James Bond and the Esprit but it was always just fiction. We thought, ‘Let’s do something everybody knows but nobody has tried.'”
The team at his firm Rinspeed replaced the petrol engine with three electric motors, one to power the rear wheels and two for the specially designed propellers. They are capable of taking it to 75mph on land, a more sedate 4mph while cruising in “boat” mode and a positively tranquil 2mph while underwater.
The company also claims that the car is extremely “green” as well, as it is a zero-emission vehicle powered by rechargeable lithium-ion batteries.
