Forza Horizon 5's Warthog Easter Egg: A 117 MPH Love Letter to Halo

It was a warm digital evening on Mexico’s Pacific coast in 2026 when a player known as Divide-By-Zero88 decided to push the Halo Warthog to its absolute limit. The road stretched out like a ribbon of gold, the futuristic war machine hummed under the desert sun, and then the speedometer locked in at a very specific number: 117 miles per hour. To a casual racer, that might have looked like just another stat. But to anyone who has ever spent time in the Halo universe, the number hit like a freight train—it was a direct nod to Master Chief, the iconic Spartan known as John-117. That is the kind of small, clever discovery that keeps Forza Horizon 5 feeling fresh, even years after its original launch.

Forza Horizon 5, developed by Playground Games, dropped players into an open-world recreation of Mexico back in late 2021. From the moment early access began, the game was a runaway hit—nearly a million players jumped in before the official November 9 launch. Fast-forward to 2026, and the racing sim has only grown bigger. PS5 drivers finally got behind the wheel in 2025, and the community is still dissecting every tiny detail like it just rolled off the assembly line. Players can customize their own driver, choose from a garage full of real-world manufacturers such as Dodge and Audi, and tackle countless race types across a stunning map. But when the Halo Warthog shows up in the lineup, it is hard to pass up the chance to go full sci-fi soldier.

The Warthog itself has never been a typical racing machine. It looks like a tank crossed with a dune buggy, and it has appeared in previous Forza Horizon titles as well. In Forza Horizon 5, however, the secret under the hood is the real kicker. Divide-By-Zero88 was fiddling with upgrades when they realized the base top speed of the Warthog sits at 117 mph. Not 120, not 115, but 117. That number is a dead giveaway for Halo fans: it matches the 117 in John-117, the Master Chief's real name. Playground Games could have chosen any number, but this choice was clearly a love letter to one of Xbox's most iconic characters. It is a small touch, but it hits the bullseye.

That 117 mph speed is also the cherry on top of a vehicle that already turns heads. Tearing down the gorgeous roads of Mexico in a massive sci-fi military transport never gets old. Adding engine upgrades can push the Warthog even faster, but leaving it stock lets players appreciate the reference in all its glory. It is one of those moments where a game stops being just a game and becomes a conversation between developer and player.

The Warthog Easter egg is not the only nod to Xbox history hidden in Forza Horizon 5. Several unlockable car horns play tunes and sounds from other beloved titles published by Xbox Game Studios. Here is a quick look at how Playground Games tips its cap to its fellow franchises:

By 2026, these Easter eggs have become part of Forza Horizon 5's long-term charm. New players still stumble across the 117 mph detail and post about it, while veterans smile and say, Welcome to the club. It proves that Playground Games was not content to build just another racing simulator. They built a world full of small tributes to the broader Xbox family. For anyone who loves Halo, driving the Warthog in Forza Horizon 5 is a no-brainer. And when the speedometer pegs at 117, it feels less like a coincidence and more like a secret handshake. 🎮

Forza Horizon 5 is available on Xbox One, Xbox Series X/S, PC, and now PlayStation 5.
