Indianapolis track announcer Tom Carnegie used to whip the crowds into frenziedexcitement during qualification runs for the famous 500, especially when he intonedhis trademark exclamation "It's... A... New Track Record!". That occurred quite often during the period 1962-1972with its unprecedented explosion in speed. Parnelli Jones became the first manto break the 150-mph barrier with a lap at 150.370 mph in 1962, then just 10years later Bobby Unser's 196.678 mph was not far short of the 200-mph mark. Thishappened because the "decade" brought extraordinary advances in car, engine andtire design, including takeover by the rear-engine configuration and theemergence of aerodynamic wings, wide slick tires and unrestricted turbochargedengines that ultimately produced over 1,000 horsepower.
