MotionCore Vehicle – Physics Character Controller for Vehicles

A free, realistic car controller for Unity, built on real wheel physics.

MotionCore Vehicle Basic gives your game a credible, fun-to-drive vehicle out of the box. It's powered by Unity's WheelCollider system — real per-wheel suspension, tire grip, motor torque, and braking — so cars have genuine weight, body roll, and momentum instead of the floaty "push the rigidbody around" feel of basic kits.

The handling is tuned for that open-world sweet spot: realistic and satisfying enough for an RPG or sandbox, planted and forgiving enough that anyone can pick up a controller and drive. Think grounded, GTA-style driving — not a punishing hardcore sim.

Why MotionCore Vehicle Basic

• Real WheelCollider physics — suspension, tire friction, motor and brake torque. No faked forces.
• Feels like a real car — weight transfer, body roll under cornering, dive under braking, squat on acceleration.
• Speed-sensitive steering — sharp and nimble when parking, calm and stable at speed, with smooth rate-limited input. No twitchy, on-rails turning.
• Handbrake drifts — pull the handbrake to swing the rear out for tight corners, then recover cleanly.
• Drop-in and ready — one menu click builds a fully drivable demo car and scene.

Features

• Rear-, front-, or all-wheel drive (RWD / FWD / AWD)
• Motor torque, braking, reverse, and a soft top-speed cap
• Per-axle anti-roll bars and speed-scaled downforce for stability
• Slip-based drift detection from real tire data
• Chase camera with switchable views (Chase / Far / Hood), toggled with C
• Keyboard and gamepad support via a clean input contract — or drive it from your own input
• Wheel visuals driven straight from the physics
• Every parameter exposed in the Inspector with tooltips for easy tuning

Built to Extend

A clean, documented API and a protected virtual hook system let you customize torque, steering, and drift behavior by subclassing — without ever editing the core. A surface-grip interface is included so you can add asphalt, grass, sand, or ice handling. Designed as the foundation for a growing family of add-ons (arcade and simulation handling).

Public state (SpeedKph, ForwardSpeed, IsGrounded, IsDrifting, and more) makes hooking up HUDs, audio, and gameplay trivial.

What's Included

• The WheelCollider-based vehicle controller and a ready-to-use car component
• Chase camera and input components
• One-click demo scene builder
• Full documentation: setup, architecture, tuning, and demo guides
• Clean, commented C# source with assembly definitions

Requirements

• Unity 6 (6000.0) or newer
• Input System package (com.unity.inputsystem)
• No third-party dependencies

Perfect for open-world games, RPGs, driving and racing prototypes, GTA-style sandboxes, and any project that needs a solid, believable car controller you can build on.
