# Vehicles, racing and machinery
Vehicle mechanics connect controls, momentum, routes and machine condition; the chosen simplifications should stay consistent. Each overview separates player actions, state changes and alternative rules. Examples are hypothetical design scenarios, not claims about a named game. A prototype check states an observable question for the next iteration. Existing detailed references remain separately linked from the direction map.
## Mechanics and variants
### 1. Arcade racing
id: t139
canonicalId: vehicles-racing--t139
url: https://gamemechanics.pro/en/mechanics/vehicles-racing/#t139
Arcade racing makes lines, acceleration timing and positional contests readable through simplified vehicle motion.
#### Mechanic variants
- Boost spends reserves for a brief advantage.
- Steering assistance maintains usable racing lines.
- Shortcuts trade risk against route length.
- Catch-up rules change how closely racers compete.
Design example: Boosting before a bend passes a rival but complicates entry into a narrow tunnel.
Prototype check: Test understandable speed losses and assistance behavior when surface types change within a bend.

### 2. Driving simulators and car tuning
id: t140
canonicalId: vehicles-racing--t140
url: https://gamemechanics.pro/en/mechanics/vehicles-racing/#t140
Vehicle setup changes track behavior to align handling, component endurance and a selected driving style.
#### Mechanic variants
- Gear ratios trade acceleration against top speed.
- Suspension changes responses to uneven ground.
- Brake balance changes entry stability.
- Wear requires revisiting the initial setup.
Design example: Short gearing helps on a climb but limits speed on a long straight.
Prototype check: Compare one setup variable at a time on the same section and identify the vehicle model's simplifications.

- [OpenTTD: About](https://www.openttd.org/about)
### 3. Rally, off-road driving and traction
id: t141
canonicalId: vehicles-racing--t141
url: https://gamemechanics.pro/en/mechanics/vehicles-racing/#t141
Changing grip connects line choices to surface conditions and the next section rather than one constant cornering speed.
#### Mechanic variants
- Gravel increases braking uncertainty.
- Ruts guide wheels and restrict line changes.
- Reconnaissance describes a hidden turn.
- Water changes the usable safe pace.
Design example: A driver slows before a crest because notes warn of a gravel turn immediately beyond it.
Prototype check: Test surface appearance against actual grip and cue timing before blind sections.
- [Godot: Physics introduction](https://docs.godotengine.org/en/stable/tutorials/physics/physics_introduction.html)
- [OpenTTD: About](https://www.openttd.org/about)
### 4. Drifting, stunts and skid control
id: t142
canonicalId: vehicles-racing--t142
url: https://gamemechanics.pro/en/mechanics/vehicles-racing/#t142
Controlled skids and stunts turn reduced grip into scored actions with deliberate entry, sustain and recovery phases.
#### Mechanic variants
- Drift angle raises reward alongside risk.
- Transitions require smoothly switching sides.
- Landings test orientation and velocity.
- Repeated tricks reduce the value of a safe pattern.
Design example: A player connects two drifts across a straight while preserving speed without wall contact.
Prototype check: Test distinction between a controlled drift and ordinary sliding and explain why a chain ends.
- [Godot: Physics introduction](https://docs.godotengine.org/en/stable/tutorials/physics/physics_introduction.html)
- [OpenTTD: About](https://www.openttd.org/about)
### 5. Combat racing and pursuit
id: t143
canonicalId: vehicles-racing--t143
url: https://gamemechanics.pro/en/mechanics/vehicles-racing/#t143
Combat racing adds target and defense choices to speed management, changing the field's order along a route.
#### Mechanic variants
- Weapons need suitable range and angles.
- Shields are spent around a visible warning.
- Traps punish predictable racing lines.
- Pursuits assign different fugitive and chaser goals.
Design example: A chaser traps a shortcut and forces the leader to consider a longer bypass.
Prototype check: Test counterplay to consecutive attacks so loss of control cannot become an endless chain.

### 6. Motorcycle racing and two-wheel balance
id: t144
canonicalId: vehicles-racing--t144
url: https://gamemechanics.pro/en/mechanics/vehicles-racing/#t144
Two-wheeled vehicles connect turning and stability to balance, line selection and handling uneven surfaces.
#### Mechanic variants
- Leaning establishes entry into a turn.
- Weight shifts change behavior during jumps.
- Braking before obstacles requires preparation.
- Surface contact determines balance recovery.
Design example: A player shifts weight before landing to remain stable for a following short turn.
Prototype check: Test visual balance feedback and an alternative scheme for devices without analog triggers.
- [Godot: Physics introduction](https://docs.godotengine.org/en/stable/tutorials/physics/physics_introduction.html)

### 7. Aviation and aerial combat
id: t145
canonicalId: vehicles-racing--t145
url: https://gamemechanics.pro/en/mechanics/vehicles-racing/#t145
Flight connects orientation, speed and energy reserves while aerial combat adds advantageous approach selection.
#### Mechanic variants
- Climbing trades speed for position.
- Turning changes heading at an energy cost.
- Interception predicts a meeting point.
- Damage restricts the usable maneuvering envelope.
Design example: An aircraft climbs above an opponent, but an excessive climb leaves insufficient speed for the next maneuver.
Prototype check: Test understandable control loss and chosen flight-model simplifications separately from decorative effects.

### 8. Spaceflight and orbital maneuvers
id: t146
canonicalId: vehicles-racing--t146
url: https://gamemechanics.pro/en/mechanics/vehicles-racing/#t146
Space maneuvers change trajectories through thrust, requiring planning reserves and later encounters rather than continuously steering at a target.
#### Mechanic variants
- Burns change a future trajectory.
- Docking requires matching relative velocity.
- Fuel limits the number of corrections.
- Maneuver nodes preview expected results.
Design example: A craft first matches station velocity and only then closes the remaining distance.
Prototype check: Test velocity reference frames and clarify whether the game uses orbital motion or simplified free movement.

### 9. Marine vehicles and submersibles
id: t147
canonicalId: vehicles-racing--t147
url: https://gamemechanics.pro/en/mechanics/vehicles-racing/#t147
Marine controls connect inertia and environment to routing, while submersibles add depth choice and limited visibility.
#### Mechanic variants
- Inertia requires starting braking early.
- Currents change paths relative to the map.
- Draft limits the depth of usable passages.
- Sonar provides incomplete views of hidden obstacles.
Design example: A tug begins turning before entering a narrow channel to account for a cross-current.
Prototype check: Test the distinction between water-relative and shore-relative speed when both affect game rules.
- [Godot: Physics introduction](https://docs.godotengine.org/en/stable/tutorials/physics/physics_introduction.html)
- [OpenTTD: About](https://www.openttd.org/about)
### 10. Rail, freight and passenger transport simulators
id: t148
canonicalId: vehicles-racing--t148
url: https://gamemechanics.pro/en/mechanics/vehicles-racing/#t148
Transport operations align timetables, capacity and stops with route constraints and passenger or cargo needs.
#### Mechanic variants
- Stops require reaching a boarding zone.
- Cargo mass changes acceleration and braking.
- Timetables connect trips to transfers.
- Maintenance interrupts vehicle availability.
Design example: A heavy train brakes earlier to stop at a short platform and preserve a transfer connection.
Prototype check: Test loading, door access and timetable updates after a delay at one intermediate stop.
