RAGGED EDGE RALLY

Real roads. Measured physics. No excuses.

A rally simulation built on real elevation data, with a physics model checked by 204 automated realism gates. Supports VR and steering wheel force feedback.

SURFACE KINDS

TYRES

Carcass deflection with real static friction, load sensitivity and combined slip. Temperature, hot pressure and wear, per tyre.

SUSPENSION

Each wheel hub is its own mass on its own spring and damper. Geometry is solved from the links, so camber, bump steer and roll centre move with wheel travel.

DRIVELINE

Three locking differentials and the brakes solved together. Turbo lag that follows exhaust energy, and anti-lag.

SURFACE AND WEATHER

Wet roads carry a water film, a line that dries with running order, puddles, and ruts that deepen on a second pass.

DAMAGE

Punctures, bent suspension, overheating, lost gears. Dents, cracked glass, broken lamps and detached panels.

THE CAR / AN ORIGINAL DESIGN

JONNET RALLY RS

2.0 litre turbocharged in-line four, all-wheel drive, right-hand drive. Driver and co-driver are modelled in the cabin.
