Combustion Engine Web-Based Simulator

A web toy that lets people mix and match virtual engines — from a tiny city car setup to a screaming superbike and even a hulking truck diesel — should have been a simple nerdy delight. Instead, the real entertainment broke out in the comments, where the crowd treated the simulator like a live roast session. One user proudly bragged they built a completely absurd monster making 4,878 horsepower, which is the internet equivalent of showing up to mini golf with a rocket launcher. Naturally, that flex became part of the vibe: less “serious simulator,” more “what is the wildest engine chaos I can make before this thing explodes?”

But not everyone was impressed. The biggest grumble was basic usability, with one commenter asking why setting the throttle to 0% seemed to do absolutely nothing — not exactly confidence-inspiring for something meant to simulate how an engine behaves. Then came the real dagger: a joke that the How it Works section might as well say “Idk”, followed by the blunt accusation of “probably llm slop.” Ouch. That’s the kind of comment-section shade that instantly changes the mood from playful tinkering to full-on internet suspicion.

And because no online car crowd is complete without wishlist chaos, another person was already demanding two-stroke mode. So the community verdict? Fun, weird, a little broken, possibly nonsense — and somehow that made people even more obsessed.
