BMW is never going to build it, so this guy will instead.
The $600,000 Mercedes-AMG G63 6x6 is one of the craziest cars ever made. It's also very rare. So we're not overly surprised to find that some young whipper snapper has drawn inspiration from the six-wheeled monster to create his very own BMW 6x6, which we can assume will be done at a fraction of the price of the AMG 6x6. This is the only image of the car we could find, via ifcar on Instagram, and as you can see a BMW X5 is being used as a donor car for the impressive project.
Where the G63 6x6 uses a 5.5-liter twin-turbo V8 with some 536 hp and 560 lb-ft of torque at its disposal, the BMW will likely use something a little more low key, the carmaker's 3.0-liter direct-injection diesel inline-6 engine, which is both turbocharged and intercooled, would be our guess. There's really not much else to go on at this point, but we wish the builder well and hopefully there'll be more information and pictures of the car as the project gets closer to completion. If you have more details about the project, do let us know in the comments.
