About
Slipratio is a browser-based automotive acceleration simulator that pits real vehicles against each other on a straight-line drag strip and shows you exactly where each one wins or loses. Pick two or more cars from the public catalog, set a race distance (0–60 mph, the eighth mile, the quarter mile, a half mile, or a custom distance), and watch a live physics simulation play out in your browser.
Each car runs on Rust/WASM code compiled from real specs: peak power and torque, dyno curves where we have them, gear ratios, final drive, curb weight, frontal area, drag coefficient, tire compound and radius, drivetrain layout, and launch behavior. Track surface, ambient temperature, and altitude all feed into the same model, so a Hellcat at sea level on hot asphalt produces a different time than the same car in cold mountain air.
Think of it as an online dyno comparison crossed with a drag race calculator: a car-vs-car simulator built for owners, enthusiasts, and tuners who want to know not just which car is faster but why, gear by gear. Every result is a shareable link with the cars, conditions, and launch settings baked in, so you can pass a race around and compare notes without anyone re-entering numbers.
Head to head
Pre-loaded matchups you can run immediately. Each link opens the simulator with both cars staged.
Catalog
Recently updated entries from the public catalog. Each link is a canonical spec page with dyno data, drivetrain breakdown, and shareable simulation links.
