15. Vauxhall D-Type
The Vauxhall D-Type was the British Army’s workhorse staff car during World War I, prized for its reliability and practicality. With a robust 4-cylinder 3,969cc engine capable of carrying five passengers at speeds over 60 mph, it was widely used by officers across various fronts. Unlike luxury models, the D-Type was valued for its ruggedness and ease of maintenance, making it indispensable for navigating the challenging conditions of the Western Front.
