FIA Category A is for "special automobiles" - AKA wheeldriven cars;
For Solar powered cars; electrical engined cars; turbune engined cars; steam engined cars; hybrid engined cars and fuel cell engine cars there are now 11 weight classes. [This matches the number of FIA 2 stroke, four stroke, diesel cycle, rotary and hydrogen reciprocating, engine capacity classes].
The classes go in 499 kg steps: Class 1 - up to 499 kg, Class 2 - 500 to 999 kg, Class 3 - 1000 to 1499 kg, 1500 to 1999 kg, ............. then continuing to 4500 to 4999 kg with finally anything over 5000 kg as class 11.
