1930→1932 Bentley 8 Litre

After Bentley had won the 24 Hours of Le Mans and retired from racing, they released their largest model called simply the 8 Litre. Around 100 examples were made and they all featured custom coachwork, mainly from the firms in England. In the 1920s it was competition for the Duesenberg Model J, supercharged Bugatti Type 57, supercharged Mercedes-Benz and the Rolls-Royce Phantom II.

The centerpiece of the 8 Litre was its six-cylinder engine based of the preceeding 6½ Litre. Displacing 7982 cc, the available 220 bhp could power even the heaviest bodies to 100 mph. To reduce weight the engine’s crankcase was made from electron.

Built on the foundations of the successful Speed 6, the 8 Litre received a new lower chassis. It was built with either a 144″ short wheel base model or had the optional 156″ wheel base. This rather large chassis had a steel ladder-type frame with seven cross members. To keep weight down, many of the drive train components were mast from aluminum castings.

Bentley Sales Manager Arthur describes the car: “Eight litres! Nearly three times the cubic capacity of the never-to-be-forgotten 3! And what a motor it was! Having a six-cylinder engine with a bore and stroke of 110 mm by 140 mm respectively, and a top-gear speed range (with a ratio of 3.5 to 1) of a minimum of 6 mph and a maximum of 104 mph – what more could man ask for? Yes, indeed; and add to that an acceleration capacity of 10 mph to 100 mph in 50 seconds with a fully equipped saloon body, and surely we had the answer to the sporting motorist’s prayer? The sporting motorist! Speed cum refinement in its highest form! A creation evolved from years of racing experience!”

A 1930 edition of Autocar described how smooth the 8 Litre was: “this car can be driven really softly on its high top gear, as slowly as a man walks, and can accelerate from that without snatch and without difficulty, and the whole time the engine, being well within its power, is silent and smooth. In fact, it is only rarely apparent that there is a big engine working under the bonnet at all, and that so high a top ratio is used, when the machine is accelerated from a crawl. For all practical purposes, therefore, the machine does its work on the one gear…”

All the great English coachbuilders got a chance to body the 8 Litre including Corsica, Vanden Plas, Barker and Gurney Nutting. Of the 100 or so chassis that were built less than 20 were convertibles.

Unfortunately the released of the 8 Litre at the 1930 London Motor Show was bad timing. The Great Depression was taking its toll on luxury cars and Bentley was in a very tight financial situation. Remarkably they managed to produce 100 example of the 8 Litre before reality sunk in. Verging on bankruptcy and were bought out by rival Rolls-Royce. Afterward, the new owners had Bentley focus on entry level luxury.

The interior, which is trimmed in blue leather, shows quite well and though some fading has become evident, all leather is devoid of any rips or tears. The woodwork remains excellent, as do the gauges and headliner. The engine and bay show signs of use and road wear however it is equally indicative of a well-maintained car in every respect.

The Bentley’s exterior brightwork is very impressive and shows only minor flaws while the paintwork is also impressive and though there is wear in the higher stress areas of the car such as the fenders, door jambs and seams, it is far from requiring any attention. Lastly, the Fixed Head Roof and large sliding sunroof are in excellent condition and the sunroof operates as expected with results one would not anticipate. When fully opened, the results are quite unique as it is provides for a large window to the sky offering both driver and passenger the benefits of open air motoring with a much more convenient manner of closed comfort with a simple operation.

1931 Bentley 8 Litre James Pearce Tourer YX 5109 – sold for €483,000
YX 5109 was restored in the 1970s by Hoffman and Mountford, at which point it was rebodied in the guise of the earlier 4½ and Speed Six ‘Le Mans’ fabric touring bodies, a style which was famously only fitted to one 8 Litre car. James Pearce’s eye for a good looking sports tourer was arguably second to none and the bodywork fitted to this car is extremely well designed, in that despite retaining its original 13 ft chassis, the length of the car is hidden in its good proportions.

1931 Bentley 8-Litre Tourer YR5086 – sold for €422,489

The car presented here, an 8-Litre Bentley, chassis number YR 5086 was delivered new to Mr. A.V. Bustard of Antrim, Northern Ireland on 1 April, 1931. It was built on the 13-foot wheelbase chassis, with engine number YR 5086 and an ‘F’-type gearbox, numbered 8083. The chassis left the Cricklewood works on 7 January, 1931 to be bodied by Thrupp and Maberly, also of Cricklewood, with an enclosed limousine body.

Little is known of YR 5086’s subsequent history, but it is known to have been owned by one Mr. Dale in the late 1950s. During Mr. Dale’s ownership, the engine was rebuilt, and it is then believed to have had a succession of UK-based owners, until it was re-bodied in the mid-1960s with a Vanden Plas-style, dual-cowl touring body by Wallis. The car is pictured in Johnnie Green’s book, Bentley: Fifty Years of the Marque, on pages 111 and 113. Here, it states that the car is owned by Scott Appleby, Esq. The book was first published in 1969, so it can be assumed that it was Mr. Appleby who commissioned the new coachwork. YR 5086 has been in the United States since 1966, and it was last recorded with the Bentley Driver’s Club in 1976, until registered with them by the previous owner in 2008.
