Renault's Humorous Engine Codes: The F4Rt and F4P Motors

Did someone аt Renault have a cheeky sense of humor, or was it аll just a happy accident? Either wаy, it's hard not to crack a smile when you hear about this. So, get this: One of Renault's engine choices for the Avantime—a turbocharged 2.0-liter four-cylinder—was given the code name F4Rt. Yes, you read that right. This car literally runs on a "fart" motor, and honestly, that's not even the quirkiest thing about it.

But wait, there’s more! Digging a bit deeper, I stumbled upon another gem: the F4P engine. Over at Renault, they decided to power the Laguna with the 1.8-liter FAP motor from 1998 to 2005. And if you’re keeping score, that’s right around the time the FART motor was revving up Avantimes, Vel Satis, Espaces, Lagunas, Scénics, and Méganes until it was retired in 2017.

Sure, these engine codes and the cars they powered might be a blip on the radar here in the U.S., but come on, Fart and Fap? That's comedy gold right there—it's like finding a joke gift under the Christmas tree... or maybe tucked away in a Halloween treat bag.

Honestly, it’s probably safe to say that the folks at Renault back in the day had no clue they were setting up such a perfect punchline. But as a self-proclaimed car geek who delights in these little oddities, I can't help but feel like they left us a little prank, nestled right there in the engine bay, waiting for someone with a juvenile sense of humor (like me) to uncover it decades later.

And for that, I’m eternally amused.
