"Sneak Peek," "Exclusive Glimpse," "First Look." These terms all grab your attention when looking for the images and footage of the latest pre-production car in action. Captured during testing at a facility or real world road tests, these images can be highly sought after. After all, who doesn't yearn to see the newest automobiles before they make their "official" debut?

To prevent photos of new cars leaking to the press, automakers often use off-limits facilities around the world to do their preliminary testing. When the car is ready for its real world road test, manufacturers bring in a camouflage engineer. With tricks such as covering the car with plastic mesh and squaring the headlamps to change the overall shape, the vehicle is given a temporary facelift. The goal: to make sure that the vehicle is only seen when it's time for the big debut.
