X-Motor Racing is an Indie racing simulator with accurate physics simulation.

X-Motor Racing offers an unique experience which hasn't similar experiences. Customizable racing simulation. All is customizable because it's possible to modify all the car specifications, including the physics. This can be useful for many things. It can be useful for adapting a car to the real model car and to make it to behave as the real one, modifying the tyres physics to behave as slicks, to make the grip different depending on the temperatures, etc.
 
 


Anyway, other important target on the player experience with the simulator, specially for the people which wonder a deeper simulation, they dispose of a tool to see the telemetry of the car on real time (exactly you see the same on the graphics as what the car is "feeling" at that moment), so if I modify any parameter on suspensions or the tyres, these changes will be clearly recognized in the graphics of this tool.
 
 


All these aren't the whole features. Real circuits and models can be added and modified. As many as the player wonders with no limit on size and polys.
 
 


Our idea respecting to XMR is to give full freedom for the player. Total interactivity with the tools (the user is able to use all them) and to have a full interactivity never seen. For that Online Leagues/Championships organizators, they can get this features useful to stablish limits or parameters on the races.
 
 


Our promise is to improve XMR, from all the points of view. We think a lot in online communities and this is useful for us to improve all. The promise about improving the online feature is full. With that we do a mention that with the tools which we offer to all the users, like this MHRT real car simulation experiment:
Simulating the MHRT car
 
 


X-Motor Racing is designed for racing enthusiasts all around the world.
 
 


Now X-Motor Racing is a racing simulator and the tools to create cars and tracks. VehiclePhysics utility that allows tweak almost every aspect of the vehicle dynamics.
You can create and add any type of car, like racing car, grand tourer, sports car, roadster, supercar, Formula 1, Nascar, SUV, family car etc.
X-Motor Racing is a constantly developing project. You could always check for updates and additional tracks and cars at download page.
Our goal is to develop advanced racing simulator with tools for understanding/tweaking vehicle physics.
X-Motor Racing is distributed via Internet only.
