In 2004, an Opel interior designer named Dietmar Finger, then serving as assistant chief designer of the Corsa studio, sat at home working through a fairly unglamorous assignment, sketching the reinforcing ribs on the inside panel of a glovebox door for the upcoming Corsa D. The ribs needed to hold their shape and support the plastic, nothing more, the kind of small structural detail most drivers never think twice about. His son wandered past, looked at the sketch, and asked why he didn't just shape the ribs like a shark instead of leaving them plain.
That offhand suggestion became one of the longest-running inside jokes in the auto industry. Finger tried it, liked the result, and brought the sketch back to the studio the next day. Two decades later, a hidden shark shows up somewhere inside nearly every new Opel and Vauxhall built, a tradition that started as one designer's private joke and grew into something closer to company policy.
A Weekend Sketch That Turned Into A Company Icon
The shape worked because it solved two problems at once. Structurally, the ribs still did their job of keeping the glovebox panel rigid, and visually, they now resembled a small shark tucked into a spot most drivers would never think to examine closely. When Finger showed the sketch to Niels Loeb, the Corsa's chief designer at the time, Loeb approved it almost immediately, and the shark went into production hidden inside the glovebox of the new Corsa D.
Nobody involved seems to have treated it as anything more than a fun detail worth keeping at first. There was no marketing plan behind it, no committee decision, just a designer who liked the joke enough to carry it through to the finished car. That casualness is part of why the story has stuck around as long as it has, since it reads less like a corporate gimmick and more like something a person actually did on a slow Sunday afternoon at home, sketching, with a kid looking over his shoulder.
A Tradition That Outgrew One Designer
Once the Corsa reached production, the shark did not stay contained to that one model. Opel's interior design team began treating it as an unofficial rite of passage, and by the time later models like the Astra, Zafira, Insignia, and Adam entered development, hiding a shark somewhere in the cabin had become an expected part of finishing the job. Placement decisions were left entirely up to whichever interior chief designer was leading that particular car, and locations were kept secret even from company leadership until launch day.
Sharks have since turned up tucked into tailgate hinges, molded into center console inserts, hidden along coat hooks, and worked into the plastic near storage bins, with the exact number varying from model to model. The recently facelifted Astra reportedly hides as many as ten of them scattered through its cabin, turning what started as a private joke into something closer to a scavenger hunt built directly into the car.
Two Decades Of Sharks Hidden In Plain Sight
What began with Finger's sketch has now outlived any single designer's tenure at the company, continuing through successive interior teams long after the Corsa D that started it went out of production. Journalists ask about shark locations at nearly every new Opel launch, and current design leadership has openly encouraged the practice, treating it as a small piece of brand identity rather than a curiosity to eventually retire.
There is a loose historical footnote some enthusiasts point to as well, since Vauxhall, Opel's British sibling brand, actually began in the nineteenth century building marine engines before ever making cars. Whether that history had anything to do with the choice of a shark is unclear, and nobody at the company has ever claimed it was intentional. Most likely it is simple coincidence, the kind that makes a good story better without actually explaining anything. Either way, a joke about a glovebox rib on one ordinary Sunday turned into a tradition that has quietly outlasted the career stage of the man who started it, still hiding in plain sight in whatever new model rolls off the line next.
