The Cooper
Car Company story
begins in 1946, simply as project to build two cars for
John Cooper and
Eric Brandon and
ends with two Formula 1 World Championships and the iconic Mini Cooper. Along the way,
Cooper Cars became the largest and most successful builder of 500cc Formula 3 Cars and
helped create the industry of racing car production.
In
1946, John and Eric decided they they would build two cars for themselves to hillclimb and
race. They had already decided that a light weight, small engined car would be the only
practical way forward and the new 500 rules were ideal. They enlisted the help of John's
father, Charles who owned Cooper's
Garage in Surbiton and had been a mechanic for Kay Don prior
to the war. |

The
resulting Prototype Cooper was a simple, light design
using the remains of two Fiat 500s for front and rear suspension, a JAP
speedway engine (obtained through Charlie's motorbike connections), a simple ladder style
frame and aluminium body. Crucially, and for largely practical reasons, the engine was
placed in the middle of the car, driving a chain to the gearbox and a second chain to the
rear axle. The mid-engine layout had been used before, of course, but coupled with light
weight and good handling, Cooper Cars used it to great effect through Formula 3, 2 and
ultimately to two Formula 1 World Championships for Jack
Brabham.
Cooper 500/Formula 3 Types |
The Cooper 500
evolved as series of models from 1946 through to 1960. Usually a new model appeared each
year although later cars (Mk IX onwards) are almost identical. 500s are usually
referred to
by their Mk numbers however Coopers also recorded type (T) numbers. In many cases,
cars were also fitted with 1 litre and 1,100cc engines (usually JAP V twin), for
hillclimbs and, for a while, Formula 2, where they were also successful. These chassis
were longer and given a separate type number. Some related types are included for
completeness such as the Triumph engined sports car, trailer and two streamlined record
cars. T1 was retrospectively given to the Austin 7 special built by Charles Cooper for
John in 1936.

Approximately 320 Cooper 500 cars were
built, however it is impossible to be precise as cars were sometimes re-built and many
cars left "by the back gate" sometimes with Charlie's approval and sometimes
without!. Factory records were incomplete, at best, and many have been lost.

Cooper 500 Drivers
Prominent Cooper 500 drivers included Stirling
Moss, Les Leston, Stuart
Lewis-Evans, Ivor Bueb, Jim
Russell, Trevor Taylor, Bill Whitehouse, Cliff
Allison, "Curly" Dryden, Ken Carter, Alan Brown, Peter Collins, Don Parker,
Raymond Sommer, Harry Schell
as well as Eric Brandon and
John Cooper, himself. Graham Hill, Bernie Ecclestone
and Ken Tyrrell also began their careers in Cooper 500s. |
The Cooper works in Hollyfield Road, Surbiton in 1959. The cars
on the forecourt are a Monaco, a Mk XII and two works F1/2 cars.

The start of something big.
John, aged nine, with the first Cooper Special, built by Charlie using a motorbike engine
and gearbox in a home made chassis with chain drive to the rear, not a bad recipe! Kay
Don's sister supervises.
|
In 1936, Charlie built a second car for John, based on Austin 7 components. This car was
later given the Cooper type number of T1.

streamlined Mk V is being handed over to John Fox of San Anselmo, California. John was
setting up a Cooper dealership on the West Coast and ran the car at
Bonneville Speed
Trials in August.

In parallel to, and financed by
Cooper's success in Formula 3, the company was able to develop a range of competitive cars
for the larger classes. The brief period of 1 litre Formula 2 allowed the company to fit V
twin engines to long chassis versions of Formula 3 cars to establish the marque and then
develop sports cars and single seaters including the Cooper Bristol, Bobtail, Monaco and a
series of Formula Junior, Formula 2 and Formula 1 cars, culminating in back to back World
Championships for Jack Brabham in 1959 and 1960. A brief look at any of these cars will
reveal a clear lineage to the 500cc cars, many using transverse leaf spring and upright
suspension arrangements derived from the original prototype car and the famous curved
chassis tubes introduced for the Mk VIII 500.
Some
years later John Cooper developed a sporting version of BMC Mini, the Cooper and Cooper
"S" models which attained cult status following wins in the Monte Carlo Rally
and staring role in the film "The Italian Job". |
