    About

    The Zetta24h Sim Series brings the heart-pounding excitement of real-world multiclass endurance racing straight to your rig.
    Inspired by legendary events like the Rolex 24, 24 Hours of Le Mans, and IMSA-style battles, we feature four distinct classes running together on iconic tracks — creating unpredictable, high-stakes action where strategy, awareness, and raw pace decide the winners.
    Whether you're chasing overall glory in a prototype or fighting for class honors in a GT3 war, every stint matters. Expect clean, competitive racing with strong community vibes, professional stewarding, and full day/night cycles for that true 24-hour feel.

    Racing Classes

    GT3 Class

    The backbone of modern GT racing. Choose from 11 different manufacturer machines (Ferrari, Porsche, Lamborghini, BMW, Mercedes-AMG, McLaren, Audi, and more) — each with unique handling characteristics. Perfect balance of speed, downforce, and driver skill. Fight for overall podiums and class supremacy.

    Ford Cup

    Raw American muscle meets sim racing. The Ford Mustang Cup cars deliver high-horsepower, torque-heavy fun with plenty of character. Great for close door-to-door battles and adding some classic V8 roar to the multiclass mix.

    LMP2

    Mid-tier prototype power. The Ligier LMP2 offers serious downforce, superior cornering speed, and raw pace — but no ABS, so precision is everything. Faster than GT3s, they demand respect in traffic.

    LMP3

    The accessible prototype entry. Lighter, nimble, and still packing a punch with strong mechanical grip. Excellent for learning prototype driving while mixing it up with GTs — but watch out, they're quick in the right hands!
    Pro Tip: Prototypes fly past GTs on straights — but GTs can be monsters in traffic. Master the relative timer and blue-flag etiquette!
