The Brass Era is an American term for the early period of automotive manufacturing, named for the prominent brass fittings used during this time for such features as lights and radiators. It is generally considered to encompass 1896 through 1915, a time when cars were often referred to as horseless carriages. Elsewhere in the world, this period would be considered by antique car enthusiasts to consist of the veteran (pre-1904), and Edwardian eras, although these terms are really not meaningful outside the former British Empire. Early automakers turned to brass for their vehicles for both its looks and function, as it held up well against tarnishing and bad weather, though still requiring regular polishing to maintain its appearance. Though the automobile was invented a few years prior to the start of the Brass Era, the 20 years that make up this era represent the beginning of the automotive industry. It was a period of small-scale manufacturing, experimental designs, and alternative power systems. The middle of this period saw the introduction of Panhard et Levassor's Système Panhard, which was a front-engine, rear-drive design that became the industry standard for decades. Through this period, electric, gasoline, and steam propulsion power were the powertrains of choice, though gas-powered internal combustion engines were dominant by the end of this period. Various body styles were also in vogue at the time, including the high-wheel motor buggy (resembling the horse buggy of before 1900), runabouts, tonneaus, and other more expensive closed bodies. The vehicles most closely associated with the Brass Era were larger, more expensive luxury vehicles, such as those built by Packard, Peerless, Pierce-Arrow, Cadillac, and other premium manufacturers. 1915, the agreed-upon cutoff of the Brass Era, was the final year the Ford Model T was available with brass fitments. At this point the style had also begun to be considered outdated, and by the 1920s few if any vehicles continued to employ brass in their designs.
