Demolition Derby

Up to 100 Kei Cars hit the mud to wreck each other. The one still moving at the end wins.

What happens in the arena

Cars enter the dirt arena together and crash into each other on purpose. There is no finish line, no lap count and no fastest driver. It is endurance: the car has to take the punishment and keep moving.

Each heat takes 1 hour, with 30 minutes of actual racing: 15 minutes, an official stop to swap driver and co-driver, then another 15. The rest is entry, inspection, clearing the wrecks and cleaning the track.

The weekend

  • Fri 23/10Cars deliveredDrivers hand over their own vehicles between 08:00 and 18:00. Cars rented from the organisation are already prepared on site.
  • Sat 24/10Qualifying heatsDriver and co-driver check-in, document checks and the qualifying heats. This is the day the arena runs all day long.
  • Sun 25/10Semi-finals and Grand FinalThe semi-finals, the Grand Final and the prize-giving, alongside the rest of the event.

How you win

To qualify, the car must finish the heat moving and be able to drive under its own power.

  • Lose a wheel and you are out — even if the car still moves. A torn-off wheel counts as serious damage because it compromises safety.
  • A flat tyre alone does NOT disqualify you: if the wheel is still on and the car drives, you stay in.
  • A stalled engine only counts if it restarts. A car that has to be pushed or towed to prove it moves is eliminated.

Why the flag comes out

Crashing is the point, but not everything goes. When you see a driver warned, it was probably one of these:

  • Deliberately hitting a car that is stopped or unable to continue. When a vehicle is immobilised, the others must steer clear.
  • Hitting the door area when a car is on its side on the track.
  • Carrying on hitting after the official end-of-heat signal.

While cars are moving and racing normally, impacts are allowed anywhere on the vehicle.

When the race stops

The race is stopped as many times as needed. That is not a failure of organisation — it is the procedure. When it happens, everyone obeys the flags and the track team immediately.

  • A rollover or a crash in a dangerous position.
  • Fire, the start of a fire, or a fuel or oil leak.
  • A driver or co-driver feeling unwell, or the need for a crane and the rescue team.

Racing only resumes when race control clears it.

Two in one cabin

Each car carries at most two people: a driver and a co-driver, both registered on the entry. They swap at the official stop in the middle of the heat — which is why the race has a break in it.
