Why is the Bentley 4.5 Litre one of the most famous prewar Bentleys?
The Bentley 4.5 Litre was introduced in 1927 as a successor to the company's earlier 3 Litre model. It was developed during the period when Bentley was becoming increasingly focused on international motor racing. The car combined a large four-cylinder engine with a strong chassis and a reputation for endurance. It became particularly famous because of its connection with the Bentley racing program and the legendary Bentley Boys.
The standard 4.5 Litre used an overhead-camshaft inline-four engine with a capacity of approximately 4.4 liters. Its design emphasized durability and strong torque rather than highly stressed performance. The engine provided impressive power for its era and allowed the car to achieve high speeds. The robust construction was particularly valuable during long-distance racing events..
