"Roads? Where we're going we don't need . . . roads."
Doc Brown, Back to The Future

Cars in fiction tend to be pretty awesome. Some just look cool and go fast. Others have weapons systems and active camouflage built into them. And then there are these cars, which can transform in order to traverse terrain meant for other vehicles. Like boats. Or planes. There are practical reasons for this to be the case, of course; after all, you wouldn't want to have to give up chasing the villains because they planned a water escape that you didn't account for. The primary reason, though, is the Rule of Cool. Because being able to drive off a pier in a sports car, transform on the way down, and hit the water in a speedboat is just plain Badass.

Less drastic modifications can be expected as well for different terrain on land, like retractable tire studs for driving on ice and other slick surfaces. Any weapon systems the car is equipped with will sometimes inexplicably change in order to fit the new environment; rather than missiles, the car will have torpedos.

The Gadgeteer Genius is almost certainly the one who made all these awesome modifications. A subtrope of Cool Car and a Super-Trope for Flying Car, Hubcap Hovercraft and Amphibious Automobile. Often overlaps with Cool Boat and Cool Plane, for obvious reasons.

Examples of We Don't Need Roads include:

Anime and Manga


  • At the end of Back to The Future, Doc Brown travels forward to 2015 and gets some pretty major work done on the Delorean, including a "hover conversion" that's really more of a "flight conversion". At the end of Back to the Future III, he does the same thing to a locomotive.
    • The fact that the Delorean is a time machine in the first place qualifies it for this trope.
  • Many James Bond examples.
    • In Moonraker. Bond's gondola transforms into a hovercraft, allowing him to drive it onto the streets of Venice.
    • Scaramanga in The Man with the Golden Gun has a car that can fly (with an attachable wing and engine).
  • The Last Starfighter. Centauri's car is also a starship.
  • In Blues Brothers 2000, the updated Bluesmobile could function underwater.
  • Quorra's car in Tron: Legacy can operate in the rough terrain off The Grid, unlike most ground vehicles in Clu's arsenal.


  • Chitty Chitty Bang Bang might actually be the Ur Example of this trope. The major premise was basically "Check out this car: it can fly."
  • The Robert Heinlein novel The Puppet Masters has "triphibians": cars that can drive on land, fly through the air and travel on water.
  • Possible example (depending on how loosely you define "car"): The Terror in Jules Verne's Master of the World functions as an aircraft, boat, submarine and automobile.

Tabletop Games

  • MegaTraveller Referee's Companion. At Tech Level 8 vehicle transportation includes triphibians, which can travel on land, in the water and through the air.
  • Champions. Vehicles can have any form of movement super characters can, including flight, swimming, tunneling and even teleportation. They can also have the power of Shapeshifting so they have an appropriate form for the movement mode they're in.
  • Game Research Group's Helltank Destroyer had Triphibious Cruisers, which could travel on land, in (and under) water and through the air.
  • Car Wars has "Grasshoppers", lightweight car/helicopter hybrids. Their armour tends to be rather poor, but if someone is chasing you too closely? Well, many of them come with bombs, you see...

Video Games

  • The Spy Hunter games are probably one of the best examples of this. In addition to being able to transform into a Cool Boat, if the armor takes too much damage, it will be shed to reveal a motorcycle (or a jetski) underneath). In the sequel, it can optionally convert into an off-road mode, where the ground clearance is raised, wheels widened and the tyres have spikes come out of then, which reduces speed but significantly improves handling when offroad.
  • One of the more expensive mods you can add to your car in Streets Of Sim City is a flight modification which, well, allows you to fly. Why is this useful, you ask? Dude, you can make your car frakking fly. Who needs a reason?
  • Certain Cybran Nation warships in Supreme Commander can deploy legs and turn into a Spider Ship, walking out of the sea and onto land to support their ground forces when assaulting a shoreline.

Western Animation

Real Life

  • Hovercraft, though not the miracle originally hoped for, are effective ferries and possibly the only 'surface' vehicle that can cross minefields safely.
  • Many examples under Amphibious Automobile.
  • A few tries at Flying Car.
