Bentley 4 Litre


The Bentley 4 Litre was a motor car built on rolling chassis made by Bentley Motors Limited. The 4 litre chassis was conceived and built in a failed attempt to restore Bentley to a good financial state. Announced 15 May 1931, it used a modified four litre Ricardo IOE engine in a shortened 8 litre chassis at two-thirds of the price of the 8 Litre in an attempt to compete with the Rolls-Royce 20/25. Instead, Bentley went into receivership shortly afterward, from which it was purchased by Rolls-Royce Limited.
The conventional straight-6 engine used an bore and a stroke for a total displacement of 3.9 L and a power output of at 4,000 rpm. The engine power was not suitable for the heavy chassis.
