This elegant sedan offered a smooth, comfortable ride, powered by a 6.75-litre V8 engine, generating 194 horsepower and 389 lb-ft of torque. Weighing nearly 5,000 pounds, the Silver Shadow required robust braking performance, which is why Rolls-Royce equipped it with ventilated disc brakes, a first for the brand.
