Volkswagen Beetle Dune
Here's another concept that you might actually be able to drive. Volkswagen claims that if its Beetle Dune concept receives a positive enough response, the company will put it into production.
The car itself isn't that big a departure from the existing Beetle, it's just beefed up with bigger wheels, flared fenders, a wider stance, and a raised rear suspension.
If it does make it to production, though, you'd want to be careful taking the Dune to actual dunes – it's still front-wheel drive.
