This part covers the field of technological innovations and development, that proved to be influencial on cars and engines during the years 1895 to 1929.
   Starting with the 1895 first ever pneumatic tyres by Michelin, applied  in the Paris-Bordeaux race of that year. Only one sans-cheveau, the „l’Éclair“, was equiped with these new tyres. Although it wasn’t a succes, the advantage to the usual wheels of those days was so remarkebly, that these ware used again in the Chicago Times Herald contest later that year.
   Almost ten years later, detachable rims or „jantes amovibles“ basically ensured the win for Renault in the first Frech Grand Prix in 1906. Now the tyre could easily be changed by means of a steel ring, bolted on the wheel. Around 1912, detachable wheels found their application, in the form of all-steel wire wheels with a central locking device. Names of the British Rudge-Whithworth or the French R.A.F. wired wheels became famous.
   1912 saw the Charlatans designed and developed Peugeot hemi-head engine with 4-valves and double-ohc. This engine proved to be the precursor for many more Grand Prix race engines in later years. This very engine lasted long, as Howdy Wilcox won with it the first post-war 1919 Indianapolis 500.
   After the great war, engines such as the Frontenac, Duesenberg and Miller ruled the American race scene over many years.
   With is, features such as  front-wheel drive, all-wheel drive, four-wheel brakes and hydraulic brakes or even independent suspensions came to the fore on both sides of the ocean.
   As a result of aeroplane egine development during the war, the post-war era whitnessed supercharging as an important and tech-setting phenomenon for race car engines.
   This chapter lay-out differs from all other chapters, in that here, each technology feature will be highlighted with several magazine articles as sub-division.
