This means that cars of any engine capacity may enter. •New Zealand and Australia really the last stronghold are Ithis form of motor racing, for , in Europe and, more recently, in! ¡ America Grand Prix racing is i strictly controlled by an international formula which is al-! tered from time to time. Restrictions There are, in fact. two formulas. Formula I which limits engine capacity to 2500c.c. and Formula II which imposes a limitation of £1500c.c. Other restrictions are also l imposed in these formulas. For instance, whereas a year or two ased, no the cars must use an aviation-type fuel limited to a certain octane rating. The Formula I cars are éligible for the world drivers' and manufacturers' championships and that is why no évent in this country is likely to attain world championship status. Resourcefulness Generally the competitlons committee of the International Automobile Federation introduces a new formula wher it considers that the cars developed under the old one have reached such a stage as to be too fast. At least that is what it amounts to. Inyariably the new formula brings with it restrictions that limit speed. Also invariably after a year or so the new cars begin to equal and better the lap speeds of the cars of the preceding formula. This is, of course, the result ! of the resoucefulness and technical ability of the world's foremost automobile engineers.'
