a History of Imperia‘ Book, written in French. I am grateful to
Werner Maurer for the translation of parts of it that will be of
interest to Standard owners and enthusiasts. The photographs of

Introduction (page
9)
In the history of IMPERIA, the
studios of Piedboeuf of Liege and the factories of Pieper de
Nessonvaux had been closely working together since the beginning
of the century. In fact, Piedboeuf, located at no 63 rue de
Fragnée, produced cars as well as motorcycles around the year
1900. Pieper de Nessonvaux was a factory building and producing
since 1848, cannons, bicycles and cars.
Piedboeuf bought in around 1905
the factories Pieper, rue Gomélevay at Nessonvaux. These
factories were bankrupt. Piedboeuf bought these factories in order
to build motorcycles. The adventure of producing two wheelers went
on for some years at Nessonvaux but were abandoned to produce more
profitably "IMPERIA" cars. 1908 was the year of
launching the brand "IMPERIA" at Nessonvaux.

The banking on
the test track
The test track (1928)
(page55)
An important problem occurred at
the IMPERIA works.
For months the management of the
factory were overwhelmed by complaints, because of the frequent
road test on the roads around the factory. More and more tests
were necessary and the population got more and more fed up.
Chickens, little animals and sometimes people were victims to
these "metal monsters". The test drivers used the roads
of the village and the roads to Banneux, a road with a lot of
bends. Speeding and high revving engines made the population mad
and they were no longer willing to support the factory
The works, squeezed between two
hills, would not allow an easy solution, so the only solution was
to build a test track within the factory and using the football
field of the football club of Nessonvaux. The ring started within
the factory, then over the roof which gave a track of about one
kilometre. Only Fiat had a similar track.
This little test track became an
attraction in the region. A little causeway allowed people to
climb onto the nearside hill to watch the spectacle of car testing
over the factories roofs.

The success of the front drive
cars (1936) (page 69)
For some years, the front wheel
drive cars were very successful for IMPERIA and the development
costs of the years before were well recovered.
In 1936, serious strikes in order
to get holidays paid were shaking the IMPERIA factories at
Nessonvaux. These strikes caused problems both in preparing and
the quality of the cars, signed up for the 24 hours race in
Francorchamps, 11th July 1936, and as a consequence
their 1900cc engines, were not run in enough and they had to
abandon the race.
At this time a worker was
responsible for assembling an engine totally with the help of an
apprentice who was responsible to provide all the parts from the
storage and he was responsible to ensure that all the connecting
rods had the same weight. At the end, the worker had to put the
engine no. (e.g. 4803) on, together with his personal no. (e.g.
17) which made the engine number(e.g. no. 4803-17) and this number
was registered in the factory. This was a quality measure because
if in case of a breakdown it was known exactly who had done the
job. This kind of responsibility, though exaggerated, was
effective.
A number of other drastic
measurements, like strict non-smoking were common. This climate of
responsibility associated with new machines were probably the best
years of IMPERIA.
New models were developed, still
using the same chassis already in existence. The model TA-9 with
1645 cc, was very aerodynamic designed by the French specialist
Andreau. The car was capable of 140 km/h. It was shown at the
motor show in Brussels in January 1948, but went never in
production.
There was also a very elegant
TA-11 Jupiter with a 1910 cc engine also designed to use an
already existent chassis with a maximum speed of 115 km/h as well
as the new TA-9 with a boot at the rear.
All these innovations were made
thanks to the very successful sales of cars made before the war.
The Standard and Triumph cars
(1947)
A few months after the war,
IMPERIA re-launched the production of cars on a new basis.
Not only the cars typically
IMPERIA with Hotchkiss engines but also under their license. It
was in 1946 when a contract was signed with Standard Motor
Company.
This agreement meant at the
beginning, importing the Standard 8 and 14. In order to make these
cars more popular, IPMERIA organised 1947 a rally, titled "
Rally IMPERIA-STANDARD-TRIUMPH", ending at castle Tervuren.
A lot of IMPERIA drivers took
part and quite a number of trophies could be seen in the trophy
room on the first floor of the factory.

Assembling Vanguards (1948)
After signing the contract with
Standard Motor Company it was decided in 1948 to assemble the
Vanguard, the cars with an engine of little over than two litres,
which seemed to be promising. The contract stipulated that all the
parts had to be imported from England in order to assemble the
cars at the IMPERIA factories in Nessonvaux. This new activity,
together with assembling Adler motorcycles allowed the retention
of trained staff. In addition, the use of various Belgium parts
were also favourable to the Belgium economy. Assembling these
allowed the provision of cars, through the company in Nessonvaux
to the home market as well as the market abroad.
Therefore at Nessonvaux the
tradition and the English quality were united to tradition and
Belgium quality for the production of the Standard-Vanguard.
The first Vanguard left the
assembling line in August 1948. It was sold at the price of Frb.
95,000. The delay in delivery varied from day to day, as 800 cars
were ordered following the motor show in January 1948. All the
necessary elements for assembling the Vanguard’s arrived by
train in big wooden boxes. A new assembling line was inaugurated
on May 9, 1949 which allowed a daily output of 15 cars per day
which would give about 300 cars per month from 1950 on. This goal
was never achieved, the maximum was 10 cars which could be tested
daily on their own factory track.
Le Standard Vanguard was a
classic car, engine in front, driving the rear wheels. The
suspension was by 3 semi-elliptical springs. Hydraulic brakes by
Lockheed on all four wheels. It was recommended that in third gear
the speed should not exceed more than 105 km/h, changing of the
gears was by lever at the steering column. During the first 800 km
of the running in period of the car, 3% oil had to be added to the
petrol. Every 5000 km the oil in the rear axle had to be changed.
It was also mentioned that the colour of the body would be high
quality and long lasting.
In 1950 Nessonvaux received an
order from Madagascar for 50 Vanguards with a particular
modification The interior had to be changed of that that the rear
seats could be lowered (like now in modern cars) These cars were
painted yellow and served for the transport of the workers as well
as for the transport of bananas during the period of the harvest.
Encouraged by this order, IMPERIA decided to develop and to
commercialise this type of car. The "pick-up" Vanguard
was born.
In 1952, a new model. The
Vanguard "Belgium" was sold at Frb. 111,000, with a
better styled saloon body which was more elegant. These details
were possible through the ingenious ideas of the department
responsible for the body of the cars. The chassis of the open car
was reinforced and lowered by 45 mm to improve the driving quality
and the road holding. The back of the car got two separate wings
in a more elegant form. The car was equipped by a multiple
overdrive which could be activated without declutching. The car
body was protected against rust by "Bonderizing". One
could order the car with leather interior, wireless set and
overdrive.
In 1950, the following
IMPERIA-STANDARD-TRIUMPH cars were produced, Standard Pick-up,
Standard Estate-car, Standard cabriolet, Triumph Renown, Vanguard,
Triumph- Mayflower and the Triumph Roadster.
On May 17, 1952 a Vanguard
finished 3rd in the Grand Prix for normal cars in the
race of consumption on the circuit of Francorchamps.

Cabriolet "Nessonvaux"
1951 (page 163)
In January 1951, at the Motor
show in Brussels, stand 103 in the Palais 5 one could see the
Vanguards.
The normal Vanguard was shown, as
well as the new cabriolet "Nessonvaux" a special Belgium
construction, approved by the Standard Motor Company. At this
motor show the main aim was to show the overdrive Laycock de
Normanville, imported from England, with hydraulic function,
activated manually or electric. In all of the cabriolets, the
overdrive was standard.
This cabriolet from the IMPERIA
factory was built on the Vanguard chassis with a 4 cylinder engine
of 2088 cc with 69 horse powers at 4200 rev. with a three speed
gear box plus overdrive, single disc dry clutch. Transmission was
by prop shaft on the rear wheels. The rear axle was semi
independent. The weight was 1244 kg and needed 12 litres of petrol
per 100 km. There were three models:
Normal, inside artificial leather
and the roof only one layer
De Luxe, inside real leather and
the roof double layers
Grand luxe, like the luxe but
with everything in chrome.
This shot
clearly shows the building's history as an armaments factory
