Classes are split by engine capacity for any Two Wheel Drive (2WD) vehicle, whether Front Wheel Drive (FWD) or Rear Wheel Drive (RWD).
Four Wheel Drive (4WD) vehicles have a separate class as they have a traction advantage with all four wheels putting down the power.
Vehicles may be registered, or unregistered. See the How to Start page for some conditions.
Ipswich also runs a separate ladies class designed for the not too serious femmes, and there is a dedicted Junior class for the young to have some fun in a controlled environment.
The following classes are for 2WD cars (Vehicles below are just examples, you could be driving something unlisted!):
A Class - up to 1600cc Many late model Front Wheel Drives (FWD) eg Civic, Laser, 323, Corolla and some Rear Wheel Drives (RWD) eg Datsun 1600 (if still a 1600 engine, Early Celicas, some Escorts, Galant/Lancer.

Junior - For 14 years to 17 years, no 4WD Turbo cars
For light hearted female competitors:
Strictly Ladies - Any Vehicle Designed as a more relaxed competition. Any serious competitors are urged to just mix it in the classes as described above.
If you are unsure of the capacity of your vehicle, look under the bonnet for the compliance plate which lists what type of vehicle etc, including (normally) engine capacity.
If your car is a 2WD Turbo (or Supercharged), simply multiply the capacity by 1.7 eg A Nissan 200SX is a 2000cc (2 litre) engine, multiply by 1.7 = 3400cc ,which places it in D Class.
Rotary engines have their capacity multiplied by 1.8. eg 10a (R100, RX3) (just under 1000cc) x 1.8 = 1800cc, which is in B class, 12a (RX2, early RX7)(1200cc) x 1.8 = 2160cc,
and 13B (RX4, RX5, late RX7)(1300cc) x 1.8 = 2340cc which are both C Class.
