Get a Corvette engine, rig it up with a Dominator Jet drive, and then strap it into a floating car, and you get the WaterCar Python, the fastest and highest-performing amphibious vehicle in the world. If zipping over the water at a top speed of 60mph doesn't float your boat, it'll accelerate on land at a neck-snapping 0-to-60 speed of a mere 4.5 seconds.
Call me old fashioned, but I like all my vehicles single-purpose. If it drives on the road, I don't want it in the ocean or sky. I mean, that's just more stuff to go wrong. And wrong, my friends, is the opposite of right. And two Wrights made an airplane. ZING! Thanks for that one, dad.
Hit the jump for several more shots and a video of the thing in action (worthwhile stuff starts at 0:50).
