The Armored Car stemmed from a 1914 report that Belgian soldiers were using an armor-plated Minerva sedan car to raid the German Army. Inspired by this knowledge, Rolls-Royce quickly armored an assortment of Rolls-Royce Silver Ghosts donated by private citizens. The cars were shielded with 3/8” thick armor plate, fitted with dual rear axles and two machine guns, with 3,000 rounds of ammunition. They carried a crew of three and despite their crudeness (and four ton weight), could reliably maintain 60 mph on dirt roads, thanks to the seven-liter, six-cylinder engine.
