The 25/30 HP Wraith was the last of the pre-WW 2 small HP cars, and the first of the small horsepower chassis to be given a word name. It was introduced in 1938, and intended to have a production run of several years, but WW-2 stopped production in September of 1939. Consequently only 491 chassis were built, the fewest of any model except the pre-Silver Ghost cars and the Phantom IV, which was not offered for sale to the public. In many respects the Wraith chassis could be considered a refinement of the 25/30. However, although its engine size and bore/stroke dimensions remained the same as the previous 25/30, the engine and chassis were completely new. The Wraith chassis was 4 inches longer than the previous 25/30, and the front wheels were set back with their centers behind the radiator. These features gave the coach-builders a significantly larger platform on which to build a body. As a result, the bodies continued to become heavier, and although the Wraith engine developed more power and torque than its 25/30 predecessor, the cars were no faster. The cars greatest improvement was independent front suspension, giving it a better ride and better handling than the 35/30. Hypoid rear axle gears were now used and this made it possible to build the bodies lower on the chassis. The transmission now had synchromesh on 2nd, 3rd, and 4th gears, making the car easier to drive. The engine had fewer gears in the front (3 instead of the previous 5) and the fan continued to be the only component driven by a belt. This made the Wraith the most silent of all the Rolls-Royce cars built.
