Racer voices

Hooked on Guessing.

Race, then send us yours.

I’m constantly watching the live online races. It’s so addicting to see who was human and who was the AI.

Bernd

  • I was sure Arancio was a human. It was the AI. I still don’t believe it.

    Nikoletta

  • We vote the track, race, then argue about who was real. Best part of my lunch break.

    Simon

  • Lights out, six cars, and you can’t tell who’s real. One more race. Again.

    Jonas

  • Easy, Medium or Hard, and you never know which. Every race feels different.

    Kenji

  • Chasing the AI’s perfect lap took two seconds off my best time.

    Leila

  • Night races with the lights on the track. I forget this runs in a browser.

    Tomás

  • AI beats me every time. This game s*cks. LOL

    Dario

  • Signed in with ChatGPT and was on the grid in seconds. No download.

For hybrid racers

Your Hybrid Modes, in Your Pocket.

The same Modes as your hybrid app, on your phone with touch or a game controller. Lap the AI’s line on the bus, then race it on your floor. The Apex twins lap like the best hybrid racers. The blue one trains you, the red one tests you. Then you are ready for them on your own track. Our cars are measured to within 0.9 mm.

Training

The blue Apex trains you.

  • GhostThe blue Apex on a flying lap, the pace you chase.
  • LineThe Apex’s path in white on the road, your trail in blue behind you.
  • SectorsPurple, green or yellow on every piece shows where the time goes.
  • GapThe timing tower shows your gap to the Apex, like Formula 1.

Racing

The red Apex may invade.

  • RivalsUp to five of the hybrid app’s own opponents, true to the app.
  • LevelsEasy, Medium or Hard. Rookies at the start, Legends at the top.

Good to know

Questions.

How does a duel work?

Tap Duel and a rival pulls up beside you. It can be a person or the game’s AI. You race once, side by side, then guess who it was and see the truth.

How do rooms work?

Open a room in Racing, Online, and send your friends its code of four letters or the link. Up to six race, the AI fills the free seats, and everyone races in their own colors. Anyone can watch an open room. Racing in one needs a free ChatGPT account.

Is this an official hybrid app?

No. HotCar Racing is an independent project, not made or endorsed by Carrera or any car maker; our car names are our own. We love the real thing, though: a Carrera HYBRID set puts the race on your floor.

Does it control my real cars?

No. It all happens on screen. HotCar never connects to your real track, your cars or the controllers you race with.

Do I need a hybrid racing set?

No. The built-in tracks work on their own. A set only matters when you want to bring your own layout or build ours at home.

What does the AI actually do?

It drives your car on your track until it finds the fastest clean lap, then shows it as a line, a ghost and rivals.

Does it drive like a real car?

The layout is exact. The handling is our own model, still being tuned during the test, not a measured copy of a real car.

Does it run on phone and laptop?

Yes, in the browser: touch sticks or a paired game controller on a phone, keyboard or controller on a laptop. Not every device is tested.

Can I install it as an app?

Yes, and then Training and Racing also work offline. On Android, Chrome, Edge or Samsung Internet offer Install, and HotCar lands on your home screen and in your app list. On iPhone and iPad, open the game in Safari, tap Share, then Add to Home Screen, and keep Open as Web App on. On a computer, Chrome or Edge show Install in the address bar and HotCar sits with your other apps. Safari on a Mac uses File, then Add to Dock. In the game, Menu shows Install the app wherever your device can.

Can I put my banner on the track?

Yes: donate 100 € or more to a recognized charity and your banner stands beside our tracks for a year. How it works.

Do I need an account to play?

No. As a guest your laps stay on this device; log in with ChatGPT to keep them everywhere. Racing in a room needs it.
