Founded in 1919 on high hopes but scant capital the marque delivered a wealth of cars \u2026&#8230;&#8230;..controlled since 1998 by the German automotive giant VW, Bentley is today associated with entirely new breed of supercars such as the Arnage, Azure, Brooklands coupe and Continental Speed models \u2026&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;.&#8221;<\/p>\n<p>Stanford writing in the 1950&#8217;s commented:-<\/p>\n<p>&#8220;Bentley&#8217;s aim had always been to introduce high performance cars into the luxuary class .In 1925 a substantial amount of financial backing was found for his firm by Woolf Barnato , the diamond millionaire , a much intensified competition career was undertaken with satisfactory results , the range of Bentley cars expanded considerably &#8230;&#8230;&#8230;&#8230;as time went on , the superiority of the 3 litre began to diminish and in 1927 it was virtually replaced by the 4.5 litre \u2026&#8230;&#8230;&#8230;&#8230;.maximum speed was some 85 mph in touring trim and in 1929 \u2026&#8230;&#8230;&#8230;&#8230;its massive construction ,reliability and good all round handling the 4.5 Bentley dominated the British high-performance market in the late 1920&#8217;s <em>even though equivalent performance could be had from very much handier cars of smaller capacity \u2026&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;.<\/em><\/p>\n<p>During 1929 experimental work on the supercharged cars was carried out and in 1930 they became catalogued .A Roots blower was fitted between the front dumb irons and drew from two large SU carburettors which inhabited this somewhat vulnerable spot \u2026&#8230;&#8230;&#8230;driven direct from the nose of the crankshaft , the blower delivered mixture at ten pounds pressure &#8230;&#8230;&#8230;&#8230;.as well as completely reliable \u2026&#8230;&#8230;apart from a tendency for the engine to boil at low speeds , due to considerable reduction of cooling are , the sole fault was a staggering fuel consumption , about 10mpg against the standard cars 16mpg&#8230;&#8230;&#8230;..on the other hand it in no respect impaired the flexibility and smoothness of the engine and produced a maximum of just about 100mph despite a weight of nearly two tons . The &#8220;Blower 405&#8243; was the last big four \u2013cylinder car to be made anywhere in the world, and about 50 were sold &#8230;&#8230;&#8230;&#8230;..&#8221;<\/p>\n<p>&#8220;Bentley Motors was founded by W.O. Bentley. The first car to bear his name pulled out of New Street Mews, London in 1919.<\/p>\n<p>From modest beginnings, the company moved from strength to strength \u2013 in a relentless pursuit of both luxury and performance. Were it not for the brand\u2019s five victories at Le Mans in the 1920s, plus a sixth in 2003, this combination could be seen as a contradiction in terms. In which case, it could be said that Bentley continues to create the most acclaimed contradictions on the road today.<\/p>\n<p>Almost a century later, W.O.&#8217;s vision continues to guide our beliefs, actions and ambitions. Located in Crewe, England and owned by Volkswagen AG since 1998, Bentley Motors remains the definitive British luxury car company, crafting the world\u2019s most desirable high performance grand

The inaugural race was held 26\u201327 May 1923, and attracted many drivers, mostly French.<a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[3]<\/sup><\/a> There were two foreign competitors in the first race, <a href=\"https:\/\/en.wikipedia.org\/wiki\/Frank_Clement_(racing_driver)\">Frank Clement<\/a> and Canadian <a href=\"https:\/\/en.wikipedia.org\/wiki\/John_Duff\">John Duff<\/a>, the latter winning the 1924 competition in his personal car, a Bentley 3 Litre.<\/p>\n<p>&#8220;Made with precision and the finest material,&#8221;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[4]<\/sup><\/a> and with recent success, the luxurious Bentley cars attracted attention. After two years without success, Bentley convened a group of wealthy British men, &#8220;united by their love of insouciance, elegant tailoring, and a need for speed,&#8221; to renew Bentley&#8217;s success.<a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[5]<\/sup><\/a> Both drivers and mechanics, these men, later nicknamed the &#8220;<a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_Boys\">Bentley Boys<\/a>&#8220;, drove Bentley automobiles to victory in several races between 1927 and 1931, including four consecutive wins at the 24 Hours of Le Mans, and forged the brand&#8217;s reputation.<a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[4] <\/sup><\/a><a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[5]<\/sup><\/a><\/p>\n<p>It was within this context that, in 1927, Bentley developed the Bentley 4\u00bd Litre. Two cylinders were removed from the 6\u00bd Litre model, reducing the displacement to 4.4 litres.<a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[6]<\/sup><\/a> At the time, the 3 Litre and the 6\u00bd Litre were already available, but the 3 Litre was an outdated, under-powered model and the 6\u00bd Litre&#8217;s image was tarnished by poor tyre performance.<a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[4] <\/sup><\/a><a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[7] <\/sup><\/a><a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[8]<\/sup><\/a><\/p>\n<p>The essential difference between the Bentley 4\u00bd Litre and the Blower was the addition of a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Roots-type_supercharger\">Roots-type supercharger<\/a> to the Blower engine by engineer <a href=\"https:\/\/en.wikipedia.org\/wiki\/Amherst_Villiers\">Amherst Villiers<\/a>, who had also produced the supercharger. W. O. Bentley, as chief engineer of the company he had founded, refused to allow the engine to be modified to incorporate the supercharger. As a result, the supercharger was placed at the end of the crankshaft, in front of the radiator. This gave the Blower Bentley an easily recognisable appearance and also increased the car&#8217;s <a href=\"https:\/\/en.wikipedia.org\/wiki\/Understeer\">understeer<\/a> due to the additional weight at the front.<a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[16]<\/sup><\/a> A guard protected the two carburetters located at the compressor intake. Similar protection was used, both in the 4\u00bd Litre and the Blower, for the fuel tank at the rear, because a flying stone punctured the 3 Litre of Frank Clement and John Duff during the first 24 Hours of Le Mans, which contributed to their defeat.<a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[20] <\/sup><\/a><a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[21]<\/sup><\/a><\/p>\n<p>The crankshaft, pistons and lubrication system were special to the Blower engine.<a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[10]<\/sup><\/a> It produced 175\u00a0hp (130\u00a0kW) at 3,500 rpm for the touring model <a href=\"https:\/\/en.wikipedia.org\/wiki\/Bentley_4%C2%BD_Litre\"><sup>[22]<\/sup><\/a> and 240\u00a0hp (180\u00a0kW) at 4,200 rpm for the racing version, which was more power than the Bentley 6\u00bd Litre developed&#8221;<\/p>\n<p>Zumbrunn:-<\/p>\n<p>\u201cit was a car that singularly failed to live up to expectations, and you could argue that the esteem in which the \u201cBlower\u201d Bentley \u2026\u2026\u2026.is still held is out of all proportion to its true worth. But that would be to miss the point entirely.<\/p>\n<p>While it was never very successful in motor racing, to legions of worshippers this particular strain of Bentley is a symbol of a lost empire, one where fact and legend merge\u2026\u2026\u2026\u2026<\/p>\n<p>Ultimately, the four-cylinder leviathan proved devastatingly quick-it held lap record at Brooklands for two years-but rarely lasted the distance\u2026\u2026..<\/p>\n<p>The \u201cBlower \u201cBentley was the last of a dying breed: a proper completion car rather than a conveyance for plutocrats.

In that period Bentleys particularly works Bentleys \u2013 built up a formidable record in sports car motor racing \u2026&#8230;&#8230;&#8230;five outright victories in eight years in the famous Le Mans \u2026&#8230;&#8230;&#8230;&#8230;&#8230;&#8230;&#8221;<\/p>\n<p>Nye:-<\/p>\n<p>\u201cIn 1928 Barnato and Rubin drove a &#8220;four and a half\u201d to victory at Le Mans to underline Bentley&#8217; grip on this trial of endurance and speed.<\/p>\n<p>Meanwhile Sir Henry &#8220;Tim \u201cBirkin decided that to achieve optimum performance from WO&#8217;s design, supercharging should be adopted .the original designer never approved \u2026&#8230;&#8230;&#8230;&#8230;.always following the dictum that &#8220;there is no substitute for cubic inches&#8221; \u2026&#8230;&#8230;.the hon.Dorothy Paget financed Birkin&#8217;s plan \u2026&#8230;.and the cars were modified in her premises at Welyn&#8230;&#8230;&#8230;&#8230;..developed a staggering 240bhp at 4200 rpm but proved unreliable and incapable of translating the power to race victories .the supercharger operated well at consistently high speed such as those achieved on the Brooklands Outer Circuit banking ,and there Birkin very special single seater version excelled.

Typical forms of the era were the biplane \u2013 2 wing arrangement, with bracing struts and wires. However, the considerable frontal area caused drag. From the net :-<\/p>\n<p>&#8220;In the two decades between the end of <a href=\"https:\/\/www.britannica.com\/event\/World-War-I\">World War I<\/a> and the start of <a href=\"https:\/\/www.britannica.com\/event\/World-War-II\">World War II<\/a>, military aviation underwent a complete transformation. The typical combat aircraft of 1918 was a fabric-covered externally braced <a href=\"https:\/\/www.britannica.com\/technology\/biplane\">biplane<\/a> with fixed landing gear and open cockpits. Few aero engines developed as much as 250 horsepower, and top speeds of 200 km (120 miles) per hour were exceptional. By 1939 the first-line combat aircraft of the major powers were all-metal monoplanes with retractable landing gear. Powered by engines that developed 1,000 horsepower or more and that were supercharged to permit flight at altitudes above 9,000 metres (30,000 feet), <a href=\"https:\/\/www.britannica.com\/technology\/fighter-aircraft\">fighters<\/a> were capable of exceeding 560 km (350 miles) per hour, and some <a href=\"https:\/\/www.britannica.com\/technology\/bomber-aircraft\">bombers<\/a> flew faster than 400 km (250 miles) per hour. <a href=\"https:\/\/www.britannica.com\/technology\/gyroscope\">Gyroscopically driven<\/a> flight instruments and electrical cockpit lighting permitted flying at night and in adverse weather. Crews were seated in enclosed cockpits, were provided with oxygen for breathing at high altitudes, and could converse with other aircraft and ground stations by voice radio. <a href=\"https:\/\/www.britannica.com\/technology\/parachute\">Parachutes<\/a>, worn by a few German fighter pilots in the last days of World War I, were standard equipment.<\/p>\n<ul>\n<li>Jaray ,Rumpler gained some experience on Zeppelin construction<\/li>\n<li>Dymaxion<\/li>\n<li>Tatra<\/li>\n<li>Hitler, fascism, German motorways and competitions, sponsorship of motorsport and speed records including 2000km ADAC Trials 1933-34.The motorway network assumed long distance travel and perhaps at high speed and with fuel economy demanded aerodynamics<\/li>\n<\/ul>\n<p>The Zeppelin airships were a good description of the form and function. Like ocean liners there were steerable.<\/p>\n<p>Jaray had been trained in airship design at a time when Germany was pioneering lighter-than-air flight. Having determined that the so-called spindle shape of an airship was ideally aerodynamic, Jaray cut it in half through the equator to form an automobile body. Further study determined that, in order to give the car stability, the half-spindle shape had to be tapered out into flat wings on either side of a tapered rear. The windshield was completely curved at almost 180 degrees to ideally direct air around the car rather than over it. The design was further refined, in an era before the widespread availability of wind tunnels, by means of threads attached to the body of a prototype; the prototype was then photographed at speed on the road, and the body&#8217;s curves then adjusted to the paths of the threads\u2014what engineers called streamlines.<\/p>\n<p>Some of the German automobile marques that adopted streamlining in the interwar period include: &#8211;<\/p>\n<ul>\n<li>Mercedes Benz<\/li>\n<li>Auto Union e.g. 1939 D type<\/li>\n<li>BMW e.g. 328 2<sup>nd<\/sup> Index of Performance Le Mans 1939 [see below]<\/li>\n<li>Adler [ see below]<\/li>\n<li>Porsche<\/li>\n<li>Opel<\/li>\n<li>Maybach [see below]<\/li>\n<li>VW<\/li>\n<li>Talbot Lago 1937 T150<\/li>\n<li>1938 Dubonnet Xenia \/Hispano Suiza<\/li>\n<li>Tatra<\/li>\n<\/ul>\n<p><strong>1936 Adler Trumpf Rennwagen<\/strong><\/p>\n<p>German automaker Adler took Jaray\u2019s philosophy to heart when creating the Rennlimousine (German for \u201cracing sedan\u201d), a model they based on the Trumpf chassis. Although it was powered by a relatively low-output 56bhp 1910cc 4-cylinder engine, the secret to the model\u2019s success was its low drag coefficient.

At the time, Fulda commissioned bodybuilder D\u00f6rr &amp; Schreck in Frankfurt\/Main with the manufacture of the test car \u2013 specifying a clear-cut condition: the car had to be capable of performing high-speed tests at over 200 km\/h over longer periods of time. D\u00f6rr &amp; Schreck accepted the challenge and chose Messrs. Maybach Motorenbau as cooperation partner for the project. With the support of Baron Reinhard Koenig-Fachsenfeld, an aerodynamicist renowned in professional circles, a streamlined three-seater based on the chassis of the Maybach SW 38 was created.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"148\" class=\"wp-image-2932\" src=\"http:\/\/colinchapmanmuseum.org.uk\/wp-content\/uploads\/2019\/06\/1939-maybach-sw38-stromlinie.jpeg\" alt=\"1939-Maybach-SW38-Stromlinie\" \/> <img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"145\" class=\"wp-image-2933\" src=\"http:\/\/colinchapmanmuseum.org.uk\/wp-content\/uploads\/2019\/06\/sw38-ds-01.jpeg\" alt=\"sw38-ds-01\" \/> <img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"145\" class=\"wp-image-2934\" src=\"http:\/\/colinchapmanmuseum.org.uk\/wp-content\/uploads\/2019\/06\/sw38-ds-01-1.jpeg\" alt=\"sw38-ds-01\" \/> The Fulda coup\u00e9 with self-supporting bodywork and two-tone finish featured a long, downward-sloping rear end.

The top speed was equally made possible by an unusually low drag coefficient of cd = 0.25 (as opposed to 0.6 customary for contemporary series-production cars). Another pre-condition was that the chassis was not to weigh more than 1.6 tons.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"208\" class=\"wp-image-2938\" src=\"http:\/\/colinchapmanmuseum.org.uk\/wp-content\/uploads\/2019\/06\/sw38-ds04.jpeg\" alt=\"sw38-ds04\" \/> <img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"171\" class=\"wp-image-2939\" src=\"http:\/\/colinchapmanmuseum.org.uk\/wp-content\/uploads\/2019\/06\/1294951651961-1.jpeg\" alt=\"1294951651961 (1)\" \/> <img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"171\" class=\"wp-image-2940\" src=\"http:\/\/colinchapmanmuseum.org.uk\/wp-content\/uploads\/2019\/06\/1294951651961-1-1.jpeg\" alt=\"1294951651961 (1)\" \/> However, the car was used to a very limited extent due to the outbreak of the Second World War.
