The Rolls-Royce 20/25 hp was a passenger car that Rolls-Royce built from 1929 to 1936 as the successor to the 20 hp . The "little Rolls-Royce" was actually intended for customers who wanted to get behind the wheel, but many vehicles were sold to customers with chauffeurs.
construction
The overhead in- line six - cylinder engine was similar to that of its predecessor 20 hp; but its displacement was increased by drilling from 76 mm to 82 mm to 3699 cm³, with the stroke remaining the same at 114 mm. The engine was ventilated by a single carburetor made in-house and ignition was possible via magnet or battery. The four-speed gearbox was locked to the engine and the gear lever was on the right. From 1932 the third and fourth gears were synchronized.
The chassis with a separate frame had rigid axles at the front and rear, each suspended on semi-elliptical longitudinal leaf springs. All four wheels were fitted with drum brakes that were operated by a mechanical brake booster. The handbrake worked on separate drums on the rear axle. The well-known Rolls-Royce radiator with a triangular attachment had vertical fins that could be adjusted to control the engine cooling. Initially, the slats were set by hand with a lever on the dashboard, later versions were controlled by a thermostat.
The larger engine increased the top speed to 121 km / h, but many buyers had heavy Pullman sedan bodies installed which - as expected - limited the top speed.
3827 pieces were produced in seven years. In 1936 the larger 25/30 hp replaced the 20/25 hp. Rolls-Royce also used the engine of the 20/25 hp as the basis for the Bentley 3½ liter .
body
Only the chassis and mechanics were made by Rolls-Royce. The bodies were built and put on by wheelwright at the buyer's choice. Some of the most famous coachbuilders for Rolls-Royce chassis were Park Ward , Thrupp & Maberly , Mulliner and Hooper .
