Vehicle Damage

Vehicle damage is a gameplay mechanic in Spintires, Mudrunner, and Snowrunner.

## Description

Vehicle damage can be caused by a wide number of things. Primarily from collisions and careless driving. As a vehicle becomes more damaged they will suffer negative affects like loss of power, increased fuel consumption, and poor steering. Vehicles can be repaired by taking them to a garage, recovering them, or repairing them with any add-on or trailer with repair points. Trucks will also become visibly damaged and audibly damaged as well. Damaged vehicles will shoot sparks from the exhaust and will rapidly backfire when accelerating. Oil and other fluids can also be seen leaking from them.

## Spintires/Mudrunner

In Spintires, and Mudrunner, all vehicles use a universal meter for damage to themselves. A damaged vehicle will suffer from generally reduced performance. Critically damaged vehicles will consume much more fuel than usual and may randomly stall, forcing an engine restart to get it moving. Vehicles that are fully damaged are immobile, as their engine can't be started.

### Repairs

* Many vehicles have the ability to carry at least one attachment or trailer that grants repair points. These are universal, usable by the carrier vehicle, or others nearby.
* Garages will fully repair any vehicle and restock all missing repair points within their area of effect.

### SnowRunner

Damage in SnowRunner is greatly expanded. There are now 5 different components that can be damaged on each vehicle, each component also has its own health pool as well. The 5 new damage types are Engine, Gearbox, Tire, Fuel tanks, and Suspension. Each damage type will affect the vehicles performance in its own way. Some vehicles, such as the TUZ 420 "Tatarin", do not have proper hitboxes for certain components, making them effectively invulnerable to damage.

* Engine - Engine damage performs relatively the same as in previous games. Engines can be damaged from collisions, driving in deep water, or if the engine is hit on obstacles like rocks. Damaged engines have less power, use more fuel, and may randomly stall, forcing a restart. A destroyed engine always stalls, and hence cannot be started at all.
* Gearbox - Gearboxes primary source of damage is from driving on smooth surfaces with the differential lock engaged. Gearboxes can also be damaged if they are hit by obstacles much like engines. Damaged Gearboxes consume more fuel, and may randomly switch into neutral when driving in any other gear. When completely broken gearboxes will be stuck in neutral, making the truck immobile.
* Tires - Tires can be damaged from the tire hitting obstacles at high rates of speed like rocks or barriers. No noticeable effect occurs to the vehicle until the tire is destroyed, after which it will struggle to gain any traction and can dramatically hamper the vehicle's performance. Tires are separate from other forms of general repair in that they specifically require a stock of tires, rather than general repair points, and cannot be replaced as long as they have any durability left.
* Fuel tanks - Fuel tanks, much like transmissions, are typically hard to damage. They can be damaged by reckless driving and collisions that hit the tank directly. No noticeable effect occurs to the vehicle until the Fuel Tank is destroyed, after which it starts leaking fuel, dramatically increasing fuel consumption even with the engine off.
* Suspension - Suspension is more vulnerable than others. On some roads even driving at high speeds over seemingly minor uneven surfaces can damage the suspension. Suspension like most other components can be damaged by hitting obstacles, usually off-road. If they are destroyed, they simply stop working.

### Repairs

* Many vehicles can carry at least one spare tire for situations where one breaks down and stops functioning.
* Various vehicles can carry trailers or attachments that allow for repairs. After being depleted of their stock, they must be refilled. Much like their precesessors, they must be physically attached to the vehicle for use.
* Outside of Hard Mode, Garages repair all vehicle for free. In Hard Mode, Garages can only perform full repairs regardless of vehicle damage with class-specific costs.
