The Inbetweeners 3 teaser has already left fans asking one very strange question: how is Simon’s car back after it ended up at the bottom of a lake? Netflix has brought Simon, Will, Neil and Jay back for a new feature-length sequel, but the return of that familiar yellow-and-red Fiat has viewers seriously confused. The car famously met its fate in the Season 3 finale — so its sudden appearance in the new teaser has sparked plenty of theories.

The Inbetweeners 3: Fans Spot a Major Plot Hole in Netflix’s First Teaser

Fans of The Inbetweeners finally have a reason to get excited again. Netflix has confirmed that the beloved comedy is returning with a third feature film — but viewers have already noticed one very familiar detail that appears to raise a rather awkward question.

The announcement arrived on September 7, 2026, alongside a 40-second teaser showing the original four friends back together.

Simon Bird, Joe Thomas, Blake Harrison and James Buckley will once again play Will, Simon, Neil and Jay, bringing the famously awkward group back for another big-screen adventure.

But it was not the reunion itself that caught fans’ attention.

It was Simon’s car.

The scene is captured from within the vehicle, focusing on their facial expressions and interactions.

The return of a very familiar Fiat

In the teaser, the four friends climb into Simon’s distinctive yellow-and-red Fiat, the same car that became a recurring part of the original television series.

For longtime viewers, the sight immediately triggered memories of the early episodes. There is just one problem: that particular car was supposed to be gone for good.

Simon received the Fiat from his parents after passing his driving test, and it appeared throughout several episodes of the series.

Its eventual fate came in the series three finale, when the car rolled into a lake during the boys’ camping trip.

That has left fans wondering how Simon could possibly be driving it again.

“How is the car back?”

Viewers were quick to question the apparent continuity error after watching the teaser.

One fan asked: “How is the car back did they pull it out the lake?”

Another joked: “Somehow Simon’s car returned.”

A third viewer wondered how Simon’s car could have been repaired after spending time in the lake.

For a franchise known for its attention to awkward details and running jokes, the unexpected return of the Fiat has given fans plenty to discuss before the new movie has even been released.

Of course, there is still no explanation for the car’s appearance.

It could eventually be addressed in the film, or the vehicle may simply have been brought back as a nostalgic reference to the original series rather than as an important part of the new storyline.

The original cast is back

The new movie has been confirmed as a continuation of the existing series and films, although Netflix has revealed very little about the actual plot.

The original television series ran for three seasons between 2008 and 2010.

That was followed by two feature films. The first saw Will, Simon, Neil and Jay heading abroad together after leaving school, while the 2014 sequel followed the group as they visited Jay in Australia during his gap year.

Now, more than a decade after the second movie, the four friends are returning once again.

Original creators return for the sequel

The revival is being written and directed by the show’s original creators, Damon Beesley and Iain Morris.

Speaking about getting the group back together, the pair said:

“It’s been super-fun hanging out with our friends again, and we’re going to work hard every week to ensure there are no problemos making this new film for humans.”

The playful comment is fitting for a franchise that has always leaned heavily into the personalities and awkward dynamics of its central characters.

For now, however, the mystery of Simon’s resurrected Fiat remains unanswered.

Fans will have to wait until the new film arrives to discover whether there is a genuine explanation — or whether the car’s return is simply one more Inbetweeners joke.

The Inbetweeners 3 is currently in production, with no release date announced yet.
