    A car undetectable for radars

    ok, so i came up with this idea while looking at lamborghini reventon... as we know, there are some planes made in "stealth" technology, thanks to which they're nearly undetectable for radars. so i thought, how about making a car that would not be reflecting waves? for planes aircraft and ships it's important not to be recognized by the enemy, but it'd save much money of speed-addict not being worried by speed radars of any sort... not that i encourage such a behaviour, just curious is it technologically possible

    My UAV is technically undetectable by radar and sonar.
    He came dancing across the water
    With his galleons and guns
    Looking for the new world
    In that palace in the sun
    On the shore lay Montezuma
    With his cocoa leaves and pearls

    You may have UAV jammer but I'll still knife you in the back, noob.

    It would probably be possible, but relatively expensive and not hugely effective.

    Number plates are the main problem - they are, in many countries, a legal requirement, and offer a reflective surface at 90° to the radar beams, so making the rest of the car radar-resistant is a waste of time.

    Also, 'planes and ships are encountering radar at long range, and it is not specifically targeted, whereas cars are being targeted by focused beams at ranges of a few metres, so it is more likely that a small reflection will be registered.

    Radar detectors/jammers are also illegal in some countries, so an entire car dedicated to evading radar may be met with strong disapproval.
    Thanks for all the fish

    That's true of an EXTERIOR-mounted number plate, but nobody said it had to be exterior-mounted. - Why not go the Citroën SM-route and mount it behind a clear panel?

    Electronic "countermeasures" may be illegal, but who's to say that "accidentally" creating a full-bodykit that just happens to be RADAR-proof will be?

    Wouldn't it still be reflective to radar/laser?

    Think about it - a cockpit window on an F117 doesn't make the interior of the plane visible to RADAR. Neither would this, if done right...!

    Personally, I think the idea of a "Stealth car" would be funny!

    Not just funny.

    It'd be the best invention ever.

    Then it could be just photographed. And you'd get caught.


    It'd certainly be possible to make it invisible to radar. The hardest part would be the wheels, although you could cover them up. Aerodynamics would be a problem too. The F-117 is inherently unstable in the air. The computers basically saves the pilots ass. I bet that you wouldn't get good fuel mileage or top speed/acceleration if your car were to be shaped weirdly. Besides, I would never park it on the streets because the chances of it getting scratched would be way too high. The stealth "fighters" have whole departments dedicated to the upkeep of the stealth aspects of it. The paint needs to be scraped off and repainted everytime a panel needs to be removed for inspection/tuneups/repairs. That paint/man-hours are not cheap.

    - Short answer- it would work, it just wouldn't be cost effective.

    I bet it would look real mean though.

    Nobody said anything about photos - that's a different problem with a different solution! I have an idea though:

    A double-glazed panel covering the number plate consisting of: A type of plastic/glass that makes photography through it impossible - like the window glass on some Bentley/Rolls-Royce models. On top of that, another type (like the cockpit window glass on stealth aircraft) that maintains stealth properties.

    Indeed, all valid issues and things that would need "refinement", but the idea is still very possible. I'm guessing the reason for "stealth" technology would be to be able to get away with speeding, so I don't think fuel economy would be your biggest concern. Also, the F-117 isn't the only example of a stealth aircraft - just one of them. You could possibly still make a "stealth" car aerodynamic.

    Or you could just spend $400 bucks on a Valentine one and take your chances.

    Do what they did in t3H aWeSomZ mOViZ Redline. Drive with your lights off at night at 200m.p.h. while wearing a night-vision-monocle. And deliver Viagra to a dirty ass perv.
    I'm dropping out to create a company that starts with motorcycles, then cars, and forty years later signs a legendary Brazilian driver who has a public and expensive feud with his French teammate.

    In some countries, such cars already exist...

    They're the ones painted in the official police colors of whichever country they originate from, with blue and red flashy lights on the roof.
    Not only are they undetectable to any known radar system, but they can also skip traffic-lights whenever they feel like it just by activating the cloaking device in the form of flashing lights on the roof. This device is usually deactivated 5 or so meters after skipping the traffic-lights.
    Together with this, it has sonar jamming capabilities as well, which it does by emitting a "WOOOO-WOOOO-WOO-WOO" sound somehow detectable by humans but apparently nothing else. This is usually done when the vehicle is traveling at high speed and just wants whichever vehicle is blocking it's path to move over. I've heard this is usually done when it is imperative for the driver of said stealth vehicle not to miss a show on TV...


    If you've never seen one of these specimens in action, I suggest paying the big continent in the middle of your world map a visit. Any country on it should suffice.

    Not to mention that covering the license plates with anything is usually illegal.

    That is true, it does not need to be aerodynamically unstable. The F-22 Raptor and the F-35 Joint Strike Fighter I think all incorporate some aspects of stealth in it, although I'm not sure if they require computer assistance to keep the plane aloft. Either way, they are not fully stealthy, iirc. The B-2 bomber is also inherently unstable because it has no verticle stabilizers. The B-2 bomber and the F-117 are probably the only true stealth aircraft out there, that we know of, of course.

    Who knows what Lockheed Skunkworks and other top secret facilities have in store for us currently that we know of?

    And if you haven't noticed, I really like airplanes.

    My car is inpenatrable to radar, mostly because its so slow that no radar can pick it up!
