Ecurie Ecosse at Le Mans

Ecurie Ecosse never really got enough credit for winning Le Mans. Twice. In 1956 and 1957. I have been revising and updating our Jaguar book before publishing it as an ebook.
Wagers on the 1956 Le Mans 24 Hours would have received short odds on a win by the works Jaguar D-types. Hawthorn and Bueb, Fairman and Wharton, and Frère and Titterington looked formidable. The engines had the new 35-40 cylinder heads (inlet valves inclined at 35 degrees, exhausts at 40 degrees), raising power output from 186.32kW (250bhp) to 205.07kW (275bhp). However, within five minutes of the start two of the works cars were out, when Paul Frère’s collided with Jack Fairman’s at the Esses. The Hawthorn/Bueb car suffered misfiring due to a fault in the new Lucas fuel injection and dropped back. Fortunately Jaguar had a second string. It had disposed of former works cars to the Scottish team Ecurie Ecosse, a compliment to its organiser David Murray, acknowledging his loyalty to Jaguar since creating the team in 1952. Ninian Sanderson and Ron Flockhart saved the day by winning in an “old” car.
The following year Flockhart and Bueb led a clean sweep of four D-types. Yet another was 6th, making Jaguar’s domination of the world’s greatest sports car race complete. The factory had withdrawn from racing and in recognition of having saved its reputation in 1956, Jaguar secretly lent Ecurie Ecosse one of the latest factory 3.8 litre fuel injected engines. Its 212.53kW (285bhp) made one car comfortably faster than any of the other D-types, including Ecosse’s own second car with carburettors. Against all the odds Ecurie Ecosse won again, covering 4397.28km (2732.42miles), its weaker second string D-type only 122.31km (76miles) behind. They had outpaced or outlasted 54 of the world’s best sports racing cars. Flockhart was paired this time with Englishman Ivor Bueb, Jock Lawrence from Cullen co-drove the other car with Sanderson, and there were five Jaguars among the first six finishers, the only interloper a 3.8 Ferrari in 5th place.

Jaguar’s other test driver


RMV Sutton was test driver at Jaguar for only 14 months yet his place in Jaguar history is secure. On 30 May 1949 he drove an XK120 on the Jabbeke-Ostend motorway at 132.596mph. Jaguars had been cad’s cars; now they were classics.

Even for a professional, Belgian National Production Car records were daunting, “I had secret misgivings, bearing in mind my fastest-ever had been 110mph on a Lea-Francis at Brooklands 21 years previously.” Early one morning, Sutton took the XK to a 5-mile straight near Coventry, “It was the car that put my mind at rest as I found it delightful to handle.” XK120 at Jabbeke. Courteney Edwards, motoring correspondent of The Daily Mail (with cine) was flown to Holland for the occasion.

Roland Manners Verney Sutton (1895-1957) was Jaguar’s chief experimental test driver from February 1948 until April 1951. Norman Dewis took over with a grander title, chief test development engineer, and a wider-ranging brief that included quality and reliability. In Paul Skilleter’s Norman Dewis of Jaguar, Sutton is portrayed as, “unique, with a hangdog look, a cigarette constantly drooping from the side of his mouth. He had aristocratic connections and a Harrow education.”

He certainly had aristocratic connections. Jaguar’s first test driver was a cousin of the Duke of Rutland.

Roland or Rowland (although often referred to as Ron) Sutton was born at Abbots Langley, Hertfordshire into a well-to-do household that included a nurse, housemaid and cook. He was apprenticed to Clayton and Shuttleworth of Lincoln, which made agricultural machinery and steam traction engines. Its chairman Colonel Frank Shuttleworth at age 57 married pretty 23 year old Dorothy Clotilda, a vicar’s daughter of Old Warden, home of the aircraft collection set up by their son, racing driver and pilot Richard Shuttleworth (1909-1940).

RMV Sutton joined Rolls-Royce at Derby in the Operations Planning Department, buying a 1921 sports Hillman for £650. It seemed a lot for, “a primitive two-seater with no starter, screen-wiper or other amenities,” which could barely manage 65mph. He competed in hill-climbs and speed trials against Raymond Mays’s outwardly identical Quicksilver, of which Sutton remarked ruefully, “Judging by the difference in performance its innards must have been modified.” 'Soapy' Sutton, JDHT photograph from Paul Skilleter's Norman Dewis

Following works driver CM Harvey’s victory in a 200-mile race at Brooklands, Sutton exchanged the Hillman for the 1923 Motor Show Alvis 12/50. Works support brought success at Aston Clinton and the car was updated over three years, culminating in an official entry for the 1926 Coupe Boillot at Boulogne. Alvis won the team prize against French factory opposition and Sutton was grateful for competitions department mods that included a high ratio “solid” back axle and Rudge-Whitworth wheels. This improved Brooklands lap times but ruined tyres and he reverted to a differential for hill-climbs. The only preparation required to win the Essex 100-Mile Handicap was removing wings and windscreen.

The Sutton family wealth could not sustain RMV’s motor racing however, so it was with relief that he joined Lea-Francis in 1927 as chief tester and competition driver. Sutton raced the Cozette-blown Meadows 4-cylinder pushrod car, which developed into the production Hyper Lea-Francis that he and Frank Hallam took to an 80.6mph Class F 12-Hour record at Brooklands. Teamed with Kaye Don, George Eyston and Sammy Newsome, they won 1928 Ulster Tourist Trophy.

Sutton’s next job was with Morris Motors Engines Branch at Gosforth Street Coventry Experimental Department. He did road and track tests of the MG Tigress, racing version of the 6 cylinder 18/80 and in a letter to Chris Barker, owner of a surviving Tigress, wrote “I clocked about 95mph at Brooklands, but 100mph, which was the target, eluded us. MG blamed the engine, but we asserted that the bhp was adequate to propel the car at the requisite speed, were it not for losses in the chassis. I made the unfortunate remark, which came to the ears of Cecil Kimber, ‘The engine was contaminated by its surroundings.’ This, I think, put the lid on it, as after two prototypes MG tested the remaining three themselves.”

Sutton raced a Type 40 Bugatti and a Brooklands Riley Nine. In 1932, with CM Harvey, he won the Rootes Cup for leading at the end of the first day of the Junior Car Club’s 100-mile race at Brooklands, yet he found fulfillment testing experimental armoured fighting vehicles, so during wartime moved to Daimler. His Coventry-Climax-engined Triumph road car survived two bombs, but was blown by a third into the drawing office of the Coventry works, rendered roofless by an earlier air raid. The authorities gave him £75 to cover the loss.

The work brought him into contact with the Ministry of Supply, which in 1946 invited Daimler to sample a military Type 82 Volkswagen. Sutton’s report on the captured military Kubelwagen was unflattering, perturbed perhaps by a warning of demolition charges found in Afrika Korps’ cast-offs. A British Intelligence Objectives Sub-Committee pronounced the Volkswagen a design, “of no special brilliance apart from certain details and not to be regarded as an example of first class modern design to be copied by the motor industry.” Sutton was more prescient, “A more refined version of this type might have possibilities.”

Post-war Sutton drove a Rolls-Royce Wraith and Mark VI Bentley, describing them as, “examples of British engineering and craftsmanship that stand supreme.” He ran an electric car, borrowed complete with charging equipment, from the Brush company for several months, “at what I imagined was a negligible outlay, but received a shock of no mean voltage when my electricity bill arrived at the end of the quarter.” He found the acceleration up to 10mph fantastic, “but beyond that it tailed off and the maximum speed was no more than 20mph.” Gradients reduced it to a crawl, the rate of which he was surprised to find never varied no matter whether the incline was 1 in 40 or 1 in 8.

RMV Sutton joined Jaguar in 1948, testing tested the 2½ and 3½ Litre saloons with Walter Hassan, moving on to Mark VII prototypes with pushrod engines and then XK120s. Some early development work on the XK was done with the 1½ litre 4 cylinder twin overhead camshaft engine and air-strut suspension, “but it was never the intention of the firm to market this car and only one prototype was built.” Norman Dewis claimed that Sutton’s nickname of “soapy” was the result of his coming to work with shaving cream on his face. Others thought him perpetually begrimed and unwashed, like his overalls.

The reconnaissance trip to Belgium caused consternation. Sutton and Jack Lea, who had known Lofty England and Wally Hassan at ERA, needed to be sure that HKV500 would comfortably exceed 120mph. When they got back they reported to Ernest Rankin, Jaguar’s public relations officer, that it could but Rankin wanted to know why journalists were calling him, asking what Jaguar had been up to in Belgium.

Sutton confessed that they had popped into The Steering Wheel Club, “for a quick one,” on the way home. The clientele of the Steering Wheel, in Brick Street off Park Lane, included journalists and racing drivers. The recce also upset the formidable Joska Bourgeois, Belgian Jaguar importer, who demanded to know why she had not been in on the secret.

Rankin invited journalists on 18th May 1949 to Jabbeke, and on the 30th they flew in a chartered Sabena Douglas DC3 from Heathrow to watch HKV500, chassis number 670002, on the still incomplete Ostend motorway. Painted white to look better in photographs, with a cowl over the passenger seat and undertray to improve aerodynamics, the Royal Belgian Automobile Club timed it over a flying mile and kilometre. To prove this was no fluke it did 126.954mph with windscreen, hood and sidescreens erect.

Accurate, painstaking, fearless yet unassuming according to a tribute in The Motor, RMV Sutton left Jaguar and went back to what he loved, as Chief Development Tester of the Car and Armoured Fighting Vehicle Division at Alvis. He died after a short illness on June 29 1957.

Alfa Romeo - Jaguar Anniversaries


Two anniversaries on the eve of Goodwood Festival of Speed; Alfa Romeo is 100 and Jaguar 75. Jaguar is home-grown maybe even a little homespun by comparison with Alfa’s halcyon days, yet Alfa Romeo is the featured marque in West Sussex. It could have been that 100 is a nice round figure. It could have been that Goodwood has featured Jaguar in the past and thought it was time somebody else had a chance. Alfa has allure; it is one of the great classic makes with a history as old as motor racing. Jaguar has allure too; it is a classic and while its motor racing heritage hardly matches Alfa’s in grand prix racing, it has won Le Mans seven times (between 1951 and 1990) against Alfa Romeo’s four on the trot 1931-1934. The Cartier Style et Luxe exhibition will celebrate Italian design, another opportunity for Alfa to show off, with the pre-war supercharged 8Cs. These include the ex-Doune 1938 Sommer-Biondetti Le Mans 2.9 Coupe, an exquisite car in the lead by 12 laps on Sunday afternoon, when a front tyre burst on Mulsanne at 130mph. It retired with a broken valve, but you could still see the damage the tyre inflicted on the Superleggera body at Lord Doune’s small museum in the 1970s. It will be the Cartier Lawn’s 16th time at Goodwood.

XK120: Artistic. Ruth always laughs when she sees my reflection on the headlamp rim.
Both makes had charismatic founders. Both fell from grace. When the Italian government forced Alfa to build in Naples it produced the enchanting to drive but flakily rust-prone Alfasud. Jaguar had quality problems and an unwelcome legacy from the dog days of British Leyland. Jaguar quality is now a match for anybody, as the influential JD Power surveys prove. The jury is still out on Alfa’s quality yet its vigour is undiminished. A caveat on the stylish and swift new Giulietta concerns road noise. Hardly anybody, it seems these days, is capable of making a car that suppresses it. Jaguar is a notable exception. But it doesn’t get it on to the hallowed lawns at Goodwood.


GOODWOOD AT ITS MOST GLORIOUS

JAGUAR XF

2010 JAGUAR 3.0 Diesel Portfolio



So Jaguar, it seems, was beleaguered the year the Berlin Wall came down. The XJ220 did not come out quite like the one I described in The Sunday Times on 10 December 1989. This was the year classic car prices peaked and convinced they were going to go on increasing, like art treasures, dealers were in a frenzy. I watched one sell a car in an afternoon, for £3,000 more than he had paid for it that morning. In the end all they were doing was selling cars to other dealers, only to discover that there were not enough “speculators” to go round, and the bubble burst. Even sober firms like Jaguar were tempted to join in, however, by the time the XJ220 got into production, with a turbocharged V6 instead of a V12, the price had gone up to £290,000. There was talk of a production run of 350 but only 280 were ever made.

Jaguar is still a bit beleaguered. Ford ownership came and went. The idea that it could go into the volume business against BMW and Mercedes-Benz came and went as well. Now it wants to compete at the premium end of the market with Porsche, all a bit of a change from when Jaguar challenged keenly on value, putting Armstrong Siddeley, Alvis and others completely out of the luxury car business. The answer to “How do they do it at the price?” was by reducing overheads; Sir William Lyons imposed strict control. Only the topmost executives actually got a Jaguar with the job. The Browns Lane car park was full of Ford Prefects and Hillman Minxes.

I have been driving the 2010 XF 3.0 diesel Portfolio at £41,500, half the price of a Porsche Panamera, but in driving quality surely a match. Swift, smooth, quiet, refined, Jaguar has long mastered the bugbear of so many competitors, road noise. Ruth thought there was a bit of rustle from the wind at motorway speeds but that was only because everything else is so quiet. Jaguars have been superior

The XF’s little ceremony when you press Start is engaging. The gear selector rises obediently out of the console, the air vents swing open, the facia display lights up and you feel at once in control. It is a bit of whimsy, yet part of a policy of lifting Jaguar into the 21st century after the misapprehension that customers wanted Jaguars to look the way Jaguars used to look. This did not give the engineering much chance to shine and I suppose that build quality and exclusiveness now compensates for the old bargain prices.

How astonishing that the E-type was introduced (inflation notwithstanding) for a basic £1550, or £2200 with tax. The XF’s naught to sixty in less than 7 seconds and top speed of 150 is about the same as an E-type, although not much else is remotely similar. The E-type did about 18mpg, the XF 42. The fuel tank size is about the same, 14 gallons against the XF’s 15.3, which gives the large 5-seater a range of 643 miles against the 2-seater’s 250.

If it keeps making cars like this, Jaguar will lift the beleaguredship.
