Sure, it looks like something a Cyberman suffering a mid-life crisis might drive. But the Sea Lion can seriously move, both on land and water.
The Sea Lion can (so it’s claimed) hit 201kph on land and 96kph (~52 knots) on water, something that the designer says is only limited by horsepower; the current model uses a Mazda Rotary engine, but could be upgraded for the right buyer. On a journalist’s salary, that’s not likely to be me. [Fantasy Junction via Born Rich]
