12-18 August: Motoring Milestones

Discover the momentous motoring events that took place this week in history ……..

120 years ago this week, Henry Ford resigned as chief engineer at the main Detroit Edison Company plant in order to concentrate on automobile production [14 August 1899]………80 years ago this week, the Vintage Sports Car Club held the last auto race at Donington Park, in England, before the outbreak of World War II [12 August 1939]……Rene Dreyfus in a Delahaye won the ‘Million Franc’ challenge run at the Montlhery (FRance) circuit, beating a Bugatti and a Sefac [15 August 1939]……..60 years ago this week, sodium road lighting was tested in the UK for the first time [17 August

1959]. Because of their efficiency (measured in lumens per watt) and the ability of their yellow light to penetrate fog they became widely used………The first pictures of BMC’s new compact four-seater Mini, designed by Alec Issigonis, were revealed to the press [18 August 1959]. Designated by Leonard Lord as project ADO15 (Amalgamated Drawing Office project number 15) and the product of the Morris design team, the Mini came about because of a fuel shortage caused by the 1956 Suez Crisis. Petrol was once again rationed in the UK, sales of large cars slumped, and the market for German bubble cars boomed. Lord, the somewhat autocratic head of BMC, reportedly detested these cars so much that he vowed to rid the streets of them and design a ‘proper miniature car’. He laid down some basic design requirements: the car should be contained within a box that measured 10×4×4 feet (3.0×1.2×1.2 m); and the passenger accommodation should occupy 6 feet (1.8 m) of the 10-foot (3.0 m) length; and the engine, for reasons of cost, should be an existing unit. Issigonis, who had been working for Alvis, had been recruited back to BMC in 1955 and, with his skills in designing small cars, was a natural for the task. The team that designed the Mini was remarkably small: as well as Issigonis, there was Jack Daniels (who had worked with him on the Morris Minor), Chris Kingham (who had been with him at Alvis), two engineering students and four draughtsmen. Together, by October 1957, they had designed and built the original prototype, which was affectionately named “The Orange Box” because of its colour. The ADO15 used a conventional BMC A-Series four-cylinder, water-cooled engine, but departed from tradition by mounting it transversely, with the engine-oil-lubricated, four-speed transmission in the sump, and by employing front-wheel drive. Almost all small front-wheel-drive cars developed since have used a similar configuration, except with the transmission usually separately enclosed rather than using the engine oil. The radiator was mounted at the left side of the car so that the engine-mounted fan could be retained, but with reversed pitch so that it blew air into the natural low pressure area under the front wing. This location saved vehicle length, but had the disadvantage of feeding the radiator with air that had been heated by passing over the engine. It also exposed the entire ignition system to the direct ingress of rainwater through the grille. The suspension system, designed by Issigonis’s friend Dr. Alex Moulton at Moulton Developments Limited, used compact rubber cones instead of conventional springs. This space-saving design also featured rising progressive-rate springing of the cones, and provided some natural damping, in addition to the normal dampers. Built into the subframes, the rubber cone system gave a raw and bumpy ride accentuated by the woven-webbing seats, but the rigidity of the rubber cones, together with the wheels’ positioning at the corners of the car, gave the Mini go kart-like handling. Initially an interconnected fluid system was planned, similar to the one that Alec Issigonis and Alex Moulton were working on in the mid-1950s at Alvis. They had assessed the mechanically interconnected Citroën 2CV suspension at that time (according to an interview by Moulton with Car Magazine in the late 1990s),[citation needed] which inspired the design of the Hydrolastic suspension system for the Mini and Morris/Austin 1100, to try to keep the benefits of the 2CV system (ride comfort, body levelling, keeping the roadwheel under good control and the tyres in contact with the road), but with added roll stiffness that the 2CV lacked. The short development time of the car meant this was not ready in time for the Mini’s launch. The system intended for the Mini was further developed and the hydrolastic system was first used on the Morris 1100, launched in 1962; the Mini gained the system later in 1964. Ten-inch (254 mm) wheels were specified, so new tyres had to be developed, the initial contract going to Dunlop. Issigonis went to Dunlop stating that he wanted even smaller, 8 in (203 mm) wheels (even though he had already settled on ten-inch). An agreement was made on the ten-inch size, after Dunlop rejected the eight-inch proposition. Sliding windows allowed storage pockets in the hollow doors; reportedly Issigonis sized them to fit a bottle of Gordon’s Gin. The boot lid was hinged at the bottom so that the car could be driven with it open to increase luggage space. On early cars the number plate was hinged at the top so that it could swing down to remain visible when the boot lid was open. This feature was later discontinued after it was discovered that exhaust gases could leak into the cockpit when the boot was open. The Mini was designed as a monocoque shell with welded seams visible on the outside of the car running down the A and C pillars, and between the body and the floor pan. Those that ran from the base of the A-pillar to the wheel well were described as ‘everted’ (lit., ‘turned outward’) to provide more room for the front seat occupants. To further simplify construction, the hinges for the doors and boot lid were mounted externally. Production models differed from the prototypes by the addition of front and rear subframes to the unibody to take the suspension loads, and by having the engine mounted the other way round, with the carburettor at the back rather than at the front. This layout required an extra gear between engine and transmission to reverse the direction of rotation at the input to the transmission. Having the carburettor behind the engine reduced carburettor icing, but the distributor was then exposed to water coming in through the grille. The engine size was reduced from 948 to 848 cc (57.9 to 51.7 cu in); this, in conjunction with a small increase in the car’s width, cut the top speed from 90 to 72 mph (145 to 116 km/h). In 1959, BMC and Alec Issigonis won the Dewar Trophy, for the design and production of the Mini. The Mini shape had become so well known that by the 1990s, Rover Group – the heirs to BMC – were able to register its design as a trademark in its own right………on the same day [18 August 1959] The proposed route of the M1 in England was changed to save a Midland’s forest………40 years ago this week, Alan Jones won the Austrian Grand Prix for Williams, with Jaques Villeneuve (Ferrari) second and Jacques Laffite third (Ligier) [12 August 1979]. As Austria is high up in the Austrian mountains, the

Renault turbo had an advantage and Rene Arnoux was on pole position with Alan Jones second. Then came Jean-Pierre Jabouille (Renault) and Niki Lauda in the fastest of the two Brabham-Alfa Romeos. The third row featured Gilles Villeneuve (Ferrari) and Clay Regazzoni (Williams) and the top 10 was completed by Nelson Piquet (Brabham-Alfa Romeo), Jacques Laffite (Ligier), Jody Scheckter (Ferrari) and Didier Pironi (Tyrrell). Villeneuve made an amazing start to take the lead from Jones, Lauda and Arnoux. Jabouille lost his clutch at the start and dropped to ninth but quickly caught up. Villeneuve stayed ahead until the third lap when Jones breezed ahead, while Arnoux quickly dispensed with Lauda. On lap 11 Arnoux moved to second place but he was then overtaken by Jabouille. The Renault team leader lasted only a couple of laps before the clutch finally stopped him and so Arnoux settled into second place with Villeneuve third, Scheckter fourth, Regazzoni fifth and Laffite sixth. Laffite soon moved ahead of Regazzoni and the order then stayed unchanged up front until the closing laps when Arnoux began to have fuel pickup problems in the final laps and had to pit. He dropped to sixth place. On the last lap Laffite overtook Scheckter to grab third place behind Jones and Villeneuve. Scheckter added to his World Championship total with fourth place and the final points went to Regazzoni and Arnoux…….30 years ago this week, NASCAR Winston Cup driver, Tim Richmmond (34) died of complications from

Tim Richmmond

AIDS [13 August 1989]. Although his NASCAR career lasted just seven years, Richmond’s on-track performances made an impression on the competition. In 1986, the flamboyant driver won seven races, more than any other driver, and finished a career-high third in the NASCAR Winston Cup points race. Richmond started just eight races in 1987, winning two races, one pole position, tallying three top-five and four top-10 finishes……..on the same day [13 August 1989], Nigel Mansell stormed through from 12th on the grid to win the Hungarian Grand Prix for Ferrari. The race is best remembered for Mansell’s marvellous overtaking manoeuvre on Ayrton Senna as the two came upon a back-marker at the same time…….20 years ago this week, Mika Häkkinen driving for the McLaren team won the Hungarian Grand Prix after starting from pole position [15 August 1999]. David Coulthard finished second in the other McLaren with Eddie Irvine finishing third for Ferrari. The remaining points-scoring positions were filled by Heinz-Harald Frentzen (Jordan), Rubens Barrichello (Stewart) and Damon Hill (Jordan). Häkkinen’s victory was his fourth of the season, and McLaren team’s fifth…….10 years ago this week, Germany shares in Volkswagen, Europe’s biggest carmaker, plunged after it approved a takeover of luxury auto manufacturer Porsche to create a sector giant [14 August 2009].
