Formula off road 3D Модель

formula off road is a form of off-road racing 4x4 motorsport. it was invented in iceland. in the hopes of bringing in more money for icelandic rescue teams, the teams started to show their 4wd cars in action in the icelandic hills. it soon became more of a competition between the teams, and soon the teams were building specially made vehicles for just this purpose.

formula off road takes place in closed areas with no road traffic. rock mines, for example, which are usually just outside towns, are often used because they offer the right kind of terrain. mostly the surface is driven just as it is but occasionally it is modified slightly for spectator experience. the tracks themselves are makeshift, marked by old tires, flags or sticks. on the day of the event the course marshal takes the drivers through the tracks on foot and explains how they are laid out and how they are supposed to be driven.

the formula off road usually has the following modifications:

- locked front and rear differentials as well as the centre transfer case. when one tyre is turning they all are.
- gear ratios are lowered and usually have slightly higher ratios up front. this makes the front wheels turn a little faster and makes the vehicle easier to steer in the extreme situations.
- engines are eight-cylinder petrol engines. a nitrous system gives an extra couple of hundred bhp when the pedal is floored.
- sand drag tyres for maximum traction. the unlimited class allows the use of paddle tyres that are built on racing slicks with the paddles welded on. the modified street class uses die-cast sand drag tyres with slightly smaller shovels.
- suspension is made to accommodate fast changing surfaces. the older trucks have coil springs while newer trucks have air springs that are easier to adjust according to each track. a new type of suspension is also being tested by at least one contestant. it’s similar to your typical motorcycle, where the shock absorber and the suspension arm is built into a single unit.
- a specially built roll cage is required for all vehicles.
- steering is hydraulic and not allowed on the street.
