The editors of the A&R would be unable and unwilling to campaign for the establishment of the proposed CCM&EC if there was not overwhelming evidence and current justification for its existence.
Colin Chapman’s/Lotus success, impact and achievement in Formula Junior go far beyond the track and have major consequences / implications/ lessons for today. The contribution of Colin Chapman and Formula Junior embraces:-
- Democratization and affordability of the sport
- The essential belief that there was a level playing field and participants could have a chance of success
- It inspired a vast array of engineering talent and , innovation/ concepts as witnessed by the marque list and the affordability
- It enriched British engineering and specialists [ again refer marque list]
- It gave opportunity to some of the foremost drivers of the generation like Jim Clark
- It operated as a feeder escalator inspiring drivers and engineers upwards.
This was healthy meld of aspiration, participation and innovation from a low cost base placing emphasis on ideas and an opportunity to experiment.
Formula Junior also had a beneficial economic dimension. Participants could be involved with a low cost base but if successful had the means to expand and diversify as many did.
Subscribers will recognize many of participants were successful in other branches of motorsport some continue in existence today. We shall therefore look at the opportunity for low cost participation and the means by which the proposed CCM&EC can develop this with the associated historical benefits remaining relevant today.
The editors appreciate that formula Junior like other classes intended for low cost entry eventually were partly killed by their own success. In all competitive arena’s technology increased with associated costs and what was perhaps meant to be amateur sporned professional works teams attracting the better drivers etc.
This is an initial article establishing the primary context and parameters .A fuller series will follow in which we can examine in detail:-
- Lotus compared and contrasted with its Formula Junior contemporaries.
- Expanded technical and competition history.
- Formula Junior today – the contemporary scene.
The Enabling Role of Formula Junior.
- Team managers
- Engine manufacturers and tuners
“It has always proved necessary to have some form of training ground for potential Grand Prix drivers………..after the Second world War certain constructors turned their attention to the building of Formula Three cars……..the primary object of this racing was to provide a form of racing within the reach of any enthusiast possessing some mechanical knowledge. However a side result of this formula was to provide the best ever training ground for young drivers prior to their entry into the intermediate Formula Two class then existing. Almost directly as a result of this class of racing, Great Britain found her self-possessed of the majority of the world’s best Grand Prix drivers.
So apparent was this that other nations began to look for an alternative when interest in formula three diminished .A well-known motor racing personality and Italian representative of the FIA; Count “Johnny” Lurani hit on the idea of a formula which would lead to the construction of a relatively cheap and orthodox racing car based on components used in normal production salon cars.
Immense interest was aroused immediately and many of the first Formula Juniors cars as they came to be known were constructed and driven by Italians”
Marriott seems to fully appreciate the training and experience opportunity that Formula Junior provided. He observes that:-
“Because they compete in the exhilarating atmosphere of an international Grand Prix .This is good schooling for any up and coming driver”
The Spirit and Specification
Twite records a slightly different emphasis to that of Marriott:
“Credit for the idea of Formula Junior goes to Count “Johnny” Lurani the Italian former racing driver .his idea came at a time when enthusiasm for the current 500cc formula 3 , never very strong on the Continent was very much on the wane, for it had developed into one country , one car domination , namely Britain and Cooper. Lurani’s scheme was for cheap racing cars as possible, and when the formula was made international the rules stated that the engine and gearbox must come from a production car which more than 1,000 had been made in 12 months……….As it was an Italian idea it was no surprise that Italian cars and drivers dominated early races, the Stanguellini, with front mounted Fiat engine being the most successful car. This featured the front suspension from a Fiat production car as well as a rigid back axle and was relatively cheap to produce. When the British constructions began to take an interest their approach was more professional and by the end of 1959 Elva, Lola, Gemini, Lotus and Cooper all had cars in advance state of construction…………. From then on British cars dominated Formula Junior almost exclusively with Lotus generally taking the honours”
The class of racing has been attributed to the Formula allowed cars to be constructed around Fiat parts.
It became international in 1958 but not until 1959 did Britain join with the likes of Cooper and Elva using BMC components whilst Lola and Lotus opted for Ford Anglia [see Cosworth below]
The Formula required that production engines and gearboxes should be used along with brakes from the same vehicle .Overhead camshafts were prohibited. Two engine sizes were allowed – 1100cc and weight of 400kg or 1000cc and 360kg.There were additional fixed measurements of the car.
Formula Junior was very evocative and in many respects emulated GP cars at an affordable cost. In particular many looked like scaled down Vanwalls etc. Cars and technology were a healthy diverse mix including front or rear engines, front wheel or rear wheel drive, two stroke, four stroke, air cooled, water cooled with multiple cylinders .Chassis ranged from ladder construction to monococque.
Formula Junior FIA Requirements
Marriott quotes the FIA regulations for Juniors as comprising:-
- The cars are defined as being single seater ; the fundamental elements of which are derived from touring cars recognized as such by FIA production must have exceeded 1,000 units in any consecutive twelve months]
- Minimum wheel base:6’-7.75”
- Minimum track:3’-7.252
- Maximum width [ outside measurements]:3’-1.5”
- Maximum cylinder capacity:1,100 cc
- Minimum weight: 881.8lbs [400 kg.] [See & relate technical specification tabulation] reduced to 793 lb. for models with capacity of 1,000cc or less.
- Cylinder block and cylinder head must be those of the engine belonging to a car classed by the FIA
- The gearbox must also be that of recognized touring model. There are no restrictions on the number and staging of gear ratios
- The system and principle of fuel feeding must be the same as that of the car from which the engine is taken
- Same rule applied to braking system but this rule has been modified and disc brakes now permitted
- The cylinder capacities specified may be reached by modifying the original bore [increase or reduction] but no alteration of stroke is allowed.
- The vehicle must be fitted with a self-starter device
- The body, open and giving provision for ne seat must also incorporate a roll bar round the driver’s seat protecting him from being crushed should the car turn over.
- Adequate fire protection is also required.
The following are prohibited:
- Use of an engine with overhead camshaft,
- Self-locking differential
- The number of crankshaft bearings
- Changing camshaft location
Commercial fuel only as defined by the FIA must be used and every car must be equipped with a certificate of authenticity issued by the national sports authority concerned, at the beginning of any event
or Comparative Specifications.
This information has been taken from Twite and Roberts. The editor’s hope by providing a wide cross section of cars /technical specifications several objectives can be achieved. These include:-
- To analyses Lotus against the competition
- To make deductions why it was superior
- To examine the rich , healthy and international diverse composition of the class
- To examine to what extent the class achieved its objectives of affordability
- To reveal the popularity and extent of the participation
There are many lessons to be learnt here alone.

The Terrier was typical of the front engine Juniors are captured an appearance of their much bigger/ faster GP fellows. It was designed with space frame by Len Terry. The power being provided by the Ford Anglia. Due to the layout and need to keep the driver low the engine is engine dropping downwards at the rear and resultant prop shaft facing upwards. Tyres are believed to have been 5.00 L x 13 front and 5.50 Lx 14 rear on steel wheels to keep costs down etc. the front suspension incorporated Triumph Herald uprights. The weight is estimated at approximately 10cwt.
Lola first Fomula Junior & Mk.II
Peter Roberst observation was that :-
“Elva opted for the 1100 cc upper limit. Eric Broadley produced a car based on the concept and components used in the successful Lola Mk.I [Climax powered sports racing car].The design used a tubular space frame with increased stiffness from a solid riveted under shield and stressed prop shaft tunnel. Broadley used a front engine layout with offset drive line and the rear axle and suspension to compensate. It’s believed that 13” wheels were used. Weight is estimated at 9 cwt.
It has been suggested that approximately 29 cars were built. They were not as successful as the sports racing cars
Marriott writing about formula Juniors in 1962 commented:-
“At the end of the 1960 season the Lotus had firmly established itself as the most successful Junior car in the field. Indeed it became something of a yardstick for many constructors and their design was closely, even slavishly, followed. It was called the Lotus 18 and during its first year of production a total of 125 came off the line”
Discussing the Elva Mk.I Junior, Marriott comments:-
“ The front engined version of this car was first available to private buyers in Britain in , early in 1959.It gained a rapid popularity on both sides of the Atlantic…….and sold for the low basic price of £900 which included a fully tuned engine and magnesium wheels. These were powered by either BMC or DKW”
Marriott in his account of the Formula Juniors commented:-
“The first Formula Junior Cooper made its appearance in 1960 and logically the basic design remained very close to the highly successful Formula One, Two and Three cars from the same stable. There were no radical design changes incorporated into the Junior”
Twite’s observation being:-
“The Cooper formula Junior cars followed closely the design of the Formula I car and tended to be stronger and heavier than their contemporaries. The multi tubular chassis has large diameter tubes as the main members with the minimum of bracing tubes…….”
Cooper as a major competitor / contemporary of Lotus deserves a fuller developed article and this will follow shortly.
The Condor is thought to have been devised and built by Michael Thorburn, Ted Whiteway, Bert Barrett and draughtsman Dick Barrett. Cars it’s believed were retailed at £1250 c 1961.
It’s believed that Leslie Richmond [1928-1985] built the Moorland c 1958/59 whilst based in Southall, West London. There is a possibility that the body was built by Williams and Pritchard. There are suggestions that the Moorland Junior was retailed at £950 or £800 less engine and gearbox. It’s possible that 30 cars were sold before the Chequred Flag adopted and upgraded the car. It’s possible that Les Richmond, Derek Taylor and Brad Ward and Graham warner made a contribution to design and construction.
Marriott makes the assessment reflected by others that:-
“This brilliant Italian car was constructed entirely around fiat components and its distinctive, traditional appearance stems from … building racing cars ……The finished product has the hard functional look of a thoroughbred…….Vittorio Stanguellini , an ace Fiat engine tuner , was one of the first in the field to produce a Junior. Production of his car has proceeded at a steady pace since 1958 and the total number of Formula Junior cars probably exceeds 200 to date.”
“When the Junior Formula was evolved in Italy Stanguellini became the first manufacturer to put one on the market. His Stanguellini, though appearing bulky and old fashioned by British standards , became the most successful car in Italian races.”
“The Dolphin is one of the few American built Juniors able to give good account of itself when competing against European contemporaries”
The Dolphin was designed by John Crosthwaite who it’s believed worked at both Lotus and Cooper. The Junior comprises elements of both. It’s believed that the car was built by Crost & Robert Hull, of La Jolle, California. It was considered to incorporate the best of European and American design features.
This is believed to be the abbreviated name of British Motor Car Distributors Ltd; of San Francisco and designed by Joe Huffaker.
Produced during 1960 it’s believed that approximately 20 cars were built.
It’s believed that 2 Formula Junior cars were built at Laurie Bonds garage at Loxwood, Sussex. C 1960. The design concept was quite radical comprising front wheel drive and forward power unit mounted back to front. It seems the intention was to provide an opportunity to race with minimum costs and maintenance.
“Because the Volpini was one of the first formula Juniors on the market, it has the simple construction that was one of the objectives of the Formula. But because of its fine workmanship, the price is quite high”
The Volpini is believed to have ben created by Arzani –Volpini a possible partnership between Gianpaolo Volpini and engine builder Egiolio Arzani from c 1954.
“The OSCA cars were produced by the Maserati brothers, who left the main company in Italy…….This car unusually attractive for a Formula Junior vehicle, sold well in America.”
Again Roberts observes in his book “Racing cars of the World” that:-
“Gerhard Mitter is the DKWagent for Stuttgart and has for many years raced Junior cars with DKW components. In 1959 he brought out his first Formula Junior which had great success particularly in hill climbs. Later, he has produced ten cars on the line of the prototype………for the 1961 season he fitted a DKW engine into a Lotus”
Subscribers might like to note that a Mitter tuned DKW engine was also adopted by Elva [see specifications and notes above]
This Formula Junior range is believed to have been developed by Selwyn Hayward and John Lewis of Colchester Racing Developments.
Later they would design and construct a sports racing car that would compete against Lotus in another class.
Engines and Cosworth
The engines that emerged in Formula Junior were primarily [see technical specification];-
- BMC “A” series
- Ford 105 E and Classic engines
- Fiat 1,100
Perhaps naturally many of the Italian constructors have adopted the Fiat 1,100 cc engine the original design around which the Junior Formula was virtually framed.
Alternatively the auto-Union DKW two stroke has provided an opportunity for some marques.
To a lesser extend the French made Renault, Peugeot, Simca and DB Panhard have provided sources of engine.
It’s worth noting that the basic reliable engines were capable of considerable tuning potential. Marriott suggests for example
“Maximum bhp figure for the “A2 series [as fitted in original touring car]; 34 bhp at 4,750 rpm. Maximum bhp [on modified Elva unit], 87 bhp at 7,200 rpm
Duckwoth and Costin both ex Lotus set up Cosworth. One of their first private ventures was the Ford based MAE. [Modified Anglia Engine] see advertisement “Sisters under the Skin”. This engine was used with considerable success by Lotus and other formula Junior competitor’s c 1959-1963.some observers noting that the best Formula Junior engines were Ford based. Marriott states:-
“Cosworth Engineering Ltd; are undisputed leaders in the field of 105 E conversions.Their version features high lift camshafts, special main and big end bearings, pistons, connecting rods, valve gear, modified cylinder head and inlet and exhaust manifolds. They[j4] also feature solid rocker shafts and twin double –choke Weber carburetors.Bench test versions have been made to peak at over 90 bhp whilst standard units [as fitted in the Ford New Anglia] develops 39 bhp.”
Super Speed [Conversions] Ltd
This company was based in Ilford, Essex. They tuned the Ford 105 E engine and were used by many of the manufacturers [see tabulation]
Marriott makes the important and pertinent observation that needs to be factored into assessments:-
“Works cars can be –and are –stripped after every meeting , then rebuilt, brake tested and so on, in order to eliminate the slightest fault.no private driver could hope to compete with any chance of success against such procedure where cost is only incidental”
Lotus Achievement in a Competitive /Commercial Free Market
Marriott records that:-
“But there is no mistaking the superiority of the British Formula Junior marques which swept the international board in 1960 and 1961, winning nearly every major event, with honours, in the main, being distributed between Lotus and Cooper”
Time and Place: London and the Swinging Sixties
Marriott discussing Formula Junior c 1962 noted:-
“Currently over fifty different makes of formula Junior cars are available, an indication of the strength of the movement …….In Britain, many hundreds of Juniors have been built during the last two years …….Junior racers have been exported, particularly to America ……. Although there are over one hundred different marques , the field is dominated at present , by a group of seven of which no less than five are British…………..”
The London Racing Car Show
Marriott recalls “but complacency does not exist in the world of motor racing, constructor Colin chapman came up with a brand –new Lotus, the 20 at the 1961 Racing Car Show”

The Proposed CCM&EC
The proposed museum believes that commercial considerations are both necessary and complementary with its educational objectives.
For these reasons our Business Plan includes provision for promoting products and services which share Chapman’s ideals of mechanical efficiency and sustainability. In addition we propose merchandising that explain and interprets the social and cultural context of Chapman’s designs in period. It’s suggested there will be catalogue for on line purchasing.
Marriott summed up a general consensus when he commented:-
“The Junior category developed, in two seasons, into one of the most successful ever devised. Indeed , it has become the type of racing that spectators have seen more than any other and its rise to top popularity in Britain since 1959 has been nothing short of meteoric……. Within four short years of its existence ,Formula Junior has become the most successful formula ever devised for it provides racing cars of an advanced design on which to train drivers and has already become firmly established as a logical introduction to Grand Prix racing…….Thus the aspiring driver can graduate smoothly from one single –seater to the next ”
Twite records in 1964:-
“Formula junior is now dead but its effect on motor racing has been far reaching and although the formula had only five years of International life it has led to many interesting developments in the motor racing world”
Formula Junior ended in 1963.
