LapTime Simulator gives you insights into any vehicle's track performance characteristics. Share your lap times with friends and see just who's ride comes out on top!

Designed by physics and racing experts.

Simply input a vehicle's performance specifications, and LapTime simulates a lap time, and top speed, for some of the world's most exciting race tracks. Vehicle performance specifications can either be entered from published sources, or can be gained via in-car G-meter devices.

Experiment with your vehicles's specs and see which changes produce the best gains on various race tracks. Decide which upgrades for your ride will give you the best bang for the buck!

Tracks featured include:

Laguna Seca, USA
Monte Carlo, Monaco
Monza, Italy
Mosport, Canada
Suzuka, Japan

Note: We strive to make LapTime as accurate as possible, but no simulation is perfect. LapTime is meant for comparing production cars only, and is less accurate for cars featuring large amounts of downforce such as Formula 1 cars. For motorcycles please input 1.0G for lateral acceleration. Although motorcycle riders may feel higher forces directed along the axis of the bike, the lateral component of that force may not exceed 1.0G due to lack of additional downforce beyond that which is provided by gravity alone.
