The Rolls-Royce 30 hp was one of the four passenger car models built under the contract between Charles Rolls and Henry Royce of December 23, 1904. The car was called Rolls-Royce , but was manufactured by Henry Royce's company, Royce Ltd. between 1905 and 1906 in the district of Trafford Park in Manchester , built and only in the car trade home of Charles Rolls, of CS Rolls & Co. , which costs GBP sold 890th The engine of the 30 hp was exhibited together with its complete sister models 10 hp , 15 hp , and 20 hp in December 1904 at the Paris Motor Show.
Claude Johnson insisted that a six-cylinder model be added to the Rolls-Royce range, as other luxury automakers, such as Napier & Son , built such cars. The 30 hp was discontinued when Rolls-Royce switched to the one-model strategy and only produced the 40/50 hp "Silver Ghost" .
The engine of the 30 hp consisted of three separately cast two-cylinder blocks that came from the 10 hp and were also used in the four-cylinder 20 hp model. Therefore, it also matched the other engines in terms of bore (101.6 mm) and stroke (127 mm). It was water-cooled, had a displacement of 6178 cm³ and its valves were counter-controlled (inlet valves hanging in the head, exhaust valves standing on the side). The crankshaft ran in seven main bearings, so that the vibrations were minimized, a problem that arose with many six-cylinder engines of the time, as the dynamic forces of such a long engine were not yet fully mastered at that time. The early models had high-voltage ignition with pre-charged accumulators, a buzzer and an ignition coil, the later cars had an additional magneto ignition. Since the side and rear lights were operated with petroleum and the headlights with carbide, there were no other power consumers and the batteries did not have to be charged while driving. The engine output was 30 bhp (22 kW) at 1000 min −1 . The engine speed was kept constant by a mechanical speed controller, which the driver could intervene with the accelerator pedal. Initially, a three-speed gearbox was installed, which was later replaced by a four-speed gearbox and which later all Rolls-Royce models got. The gearbox was connected to the engine by a short shaft and a leather cone clutch. In the four-speed transmission, third gear was the direct gear (ratio 1: 1) and fourth gear had an overdrive function.
The car reached a top speed of 88 km / h. The foot brake worked on a drum brake at the transmission output and the handbrake worked on drum brakes on the rear wheels. The front and rear axles were suspended from semi-elliptical longitudinal leaf springs. This suspension was additionally supported by a transverse leaf spring on the rear axle. The wagons had wooden spoked wheels.
There were two wheelbases, 2845 mm and 2997 mm; the track was the same for both chassis and was 1422 mm. Rolls-Royce only manufactured the chassis and mechanics, not the superstructures. So the cars were sold and the customers took care of the body themselves, which was available in open or closed versions.
Of the 37 copies made in 1905/1906, only one remained with the chassis number. 26355 received.
