Racing Schools

The 1930s saw the transformation from high-priced asphalt cars into pure racers, with Delage, Auto Union, Mercedes-Benz, Delahaye, and Bugatti constructing streamlined vehicles with engines producing up to 450 kW (612 hp), aided by multiple-stage supercharging
From 1928-1930 and again in 1934-1936, the maximum weight permitted was 750 kg, a rule diametrically opposed to hip racing regulations
All-inclusive use of aluminium alloys was essential to achieve lustrous weight, and in the case of the Mercedes, the paint was removed to satisfy the pressure limitation, producing the famous Blue Sky Arrows.

What separates Principle 1 from all other forms of open wheel racing, is the basic premise of F1 revolves around the genuine important issue that each team is a "constructor". That is, the chassis of the bus must be thought-through and manufactured in-house, and chassis can not be supplied to competitors on a "customer" basis. Engines are normally funded and/or developed by established extensive motor manufacturers, and can be supplied exclusively to just one team, or may be offered as "customer" engines, often to the smaller, lower-ranked teams.
