Dubbed the Goldfisch (yes, it means goldfish), this one-of-a-kind 7-Series featured a 6.6-liter V-16 engine derived from BMW’s existing V-12, BMWBlog reported in November. The resulting mill was so large it wouldn’t fit under the hood of BMW’s long-wheelbase sedan without significant modifications.

That got the heat out of the engine’s coolant, but not out of the car. For that, BMW’s engineers built in a complex trunk-lid-mounted air extraction system that pumped the unwanted heat into the car’s slipstream.
The result? A 408-horsepower executive sedan. While that may not sound like a lot by today’s standards, it was a monster 32 years ago. For context, the infamous Mercedes-Benz AMG “Hammer” boasted a 6.0-liter V-8 making 375 horsepower, and that was super sedan royalty at the time.

BMW’s impractical monster was never meant to see production, which is just fine. Things this weird should be unique. A showroom-spec Goldfisch would have come without the ridiculous engineering solutions that make this car so interesting.
