From Batman’s Batmobile to Scooby-Doo’s Mystery Machine, some of the cars in classic Hollywood productions seem like characters themselves. In others—1968’s The Love Bug, for example, or the entire Transformers franchise—they actually are.

In short, you’d probably recognize one of Hollywood’s most famous cars if it happened to be parked right in front of you, regardless of whether or not it exhibited any sentient qualities. However, what if you were only looking at a faint outline?

UK-based vehicle leasing broker Select Car Leasing created a quiz to find out just that, based on a test that car designers and manufacturers use to discern how aerodynamic certain vehicles are. In it, they place the car in a wind tunnel and blow white smoke toward it, making it obvious which design elements are affecting the path of the smoke (and how).

So Select Car Leasing developed a virtual wind tunnel for Hollywood’s venerated vehicles, tracked the hypothetical path of white “smoke” over them, and then removed the vehicles—leaving you to guess which car was there from the silhouette of the smoke waves.

Since it’s a multiple-choice quiz with three options for each question, your chances of guessing correctly are pretty good, even if you don’t remember every curve of every car in Hollywood (or even the make and model).

Along with the aforementioned movie automobiles, you’ll see possible answers from series like Back to the Future, The Fast and the Furious, Jurassic Park, and more.
