1931 Bentley 4 Litre
£325,000

- The last ever chassis built by Bentley Motors
- Highly attractive 3 position DHC
- Carries its original coachwork built by Freestone & Webb Ltd
- Performance is comparable to a Derby 3½ Litre Bentley, but with the added pleasure of vintage Bentley exhaust notes
- Exciting opportunity to acquire such an original model

Chassis No. VA4100 was the last 4-litre chassis built by Bentley Motors and possibly the last WO Bentley built by the old company. A total of fifty 4 Litre Bentleys were produced and this is one of the thirty-nine short chassis cars produced.

The car carries its original coachwork built by Freestone & Webb Ltd and is a highly attractive 3 position DHC. VA4100 is in outstanding original condition and is a car for the connoisseur.

The 4 Litre was introduced as a last ditched attempt to save the old Bentley company and was a rationalisation of the existing 6 cylinder cars. The new model had a 6 cylinder engine of 4 Litre capacity with a cylinder head designed by Ricardo. It shared the shorter 8-litre Bentley chassis and was not well received among the Bentley traditionalists.

Personally, having limited experience with 4 Litre Bentleys, I was very pleasantly surprised by the car’s performance, which is comparable to a Derby 3½ Litre Bentley but with the added pleasure of a vintage Bentley exhaust notes.

This is an exciting opportunity to acquire a highly original, attractive and significant WO Bentley at a fraction of the price of its 8 Litre relative.

This car is for sale as of November 4, 2019

1933 4-Litre Bentley Drophead Coupe. Coachwork by Freestone and Webb. Chassis No. VA 4100. Engine No. 4028. UK Reg. No. ALC 250

"The last model to be built by the old company was the 4-litre..." — John Adams & Ray Roberts, A Pride of Bentleys', New English Library, London, 1978.

This very car was the last 4-litre Bentley to be built and was probably, therefore, the very last car to be manufactured by the old Cricklewood company. It was apparently one of the chassis bought originally by Jack Barclay Ltd after production had ceased, and they had it bodied in drophead Coupe style bt Freestone & Webb Ltd. of nearby Willesdon in North London. The car's first private owner was a Mr. H. Wincott.

The 4-litre Bentley was the last model to be produced by the original Bentley company at Cricklewood but it had been intended as a salvation model aimed directly at the rival 20/25 Rolls-Royce at a time when Bentley Motors' fortunes were in serious decline and its future in jeopardy. The Bentley board had insisted that W.O. Bentley himself should make this move, but he was not happy with it.

However, the 3,915 c.c. 6-cylinder engine was a Ricardo design with pushrod operation of overhead inlet valves but side exhaust valves. The crankcase and sump were cast in elektron light alloy while the cylinder block and head were both in cast iron. The crankshaft was notably rigid, running in seven main bearings while ignition was by coil only. Engine mounting was on longitudinal tubes attached to the chassis via rubber buffers. The chassis frame employed a double-drop design. It had no less than seven cross-members and this structure, together with the modified F-Type gearbox, was very similar to that of the parallel Bentley 8-litre model although a spiral-bevel Back axle was used similar to that of the 6 1/2 litre.
