Vauxhall's fame was sealed with the Prince Henry model of 1910, which took its name from the German trials in honor of Prince Henry of Prussia. Although no match for Austro-Daimlers, the three-car Vauxhall team performed well and set the theme for the next decade. A three-litre car, the Prince Henry, grew in size and displacement over the next few years, developing 70hp and capable of 75mph.
The D-type was derived from the Prince Henry, with a new Pomeroy four-litre engine (95mm x 140mm) design with a silent chain drive for the cam shaft and magneto, fitted to a wider (36in) and longer (10ft 7in) chassis. Introduced late in 1912, the D-type became an important war weapon, as many were built as staff cars for British forces during World War I. Both King George V, on the Western Front, and General Kitchener in Jerusalem were transported in D-types. Early cars shared the same radiator found on the A-type. The model remained current until 1922 and very few Edwardian examples survive today.

Owned and extensively rallied by Noel McIntosh, this 1913 D-type is thought to be the earliest surviving example of the 25hp model. Having spent many years in South Africa, the car was restored some time ago with replica coachwork. In McIntosh's hands the Vauxhall's legendary reliability was certainly put to the test - over two decades he covered the route of the 1908 Great Race across America, Japan, Russia and Europe, crossed South Africa and covered thousands of outback miles in Australia, including the VSCCA 60th Anniversary "Around Australia Rally" in 2004. Since joining the current owner's collection in South Australia a few years ago the car has done very little work, apart from a rally to Mount Gambier with fellow Vauxhall enthusiast John Ellis at the wheel.
