Three-litre four-cylinder model replacing the earlier Flying Fifteen range position for 1907. Though its bore and stroke match the 15 HP, the period schedule gives a new 16/18 rating and updated pressure lubrication; it therefore remains a separate annual identity rather than extending the Flying Fifteen without evidence.
