RaceLineCalc Demo

RaceLineCalc Demo is a racing line calculator and track analysis tool for sim racing and motorsport. Use the optimized racing line to improve your lap times.

Try the calculation and analysis workflow

• Explore the built-in demo projects with saved results for Point Mass, Car V1, Car V2, Moto V1 and Moto V2.
• Inspect racing lines, speed, braking points and acceleration; compare runs on the same track.
• Import your own track image, calibrate its scale, outline boundaries and calculate with Point Mass.

Demo and full version

The free demo limits Point Mass calculations on your own tracks to 160 stations. Advanced models, custom presets and advanced analysis on your own projects require the full Steam version. The built-in demo projects let you explore those features without purchasing. Screenshots show a built-in demo project.




Calculations run locally on your computer. No RaceLineCalc account is required. Results depend on track geometry, model parameters and constraints; they do not guarantee real lap times or a globally optimal solution. Models use a flat track and do not account for elevation, banking, changing grip, weather or traffic. Use them as an analysis aid, not as a guarantee of safe driving.
