Rolls-Royce’s New Phantom engine, introduced in 1925, featured twin ignition with two spark plugs in each of its six cylinders. Those cylinders were cast in two sets of three, coupled by a one-piece cylinder head. Great Britain taxed automobiles based on cylinder bore. To reduce its tax penalty, the New Phantom engine was “undersquare” with its 4¼ -inch bore smaller than its 5½-inch stroke.
