New wheels for magpies while the Seventies are coming



The Simca 1100 was comissioned by the HQ in 1969.
This appealing mid-sized hatchback sedan/saloonwas wholly appreciated for its strengh and its creditable performences. It took over from the Renault R8.
Despite its quintessentially Simca clanking and resounding engine which called for regular adjustments, the SIMCA's (Société Industrielle et Mécanique de Constructions Automobiles)
(Automotive Industrial & Mechanic Manufacturing Company)
emerged as a essential part of the HQ's light vehicles fleet until the Eighties.


HQ commissioned other Simca models including the 1500 and 1501 Station Wagon/Estate. The latters' Simcamatic gearboxes performed better than their ZF counterparts fitted on the
Peugeot 404 estate/Station Wagon

Hotchkiss PL50

Modified by Arnault car bodies from a light truck in production since 1956, and serving the fire brigade from 1963 until the early 70s', the Hotchkiss PL.50 ladder truck was not fitted with a flashing light. Instead, the swiveling search light set on cab's rooftop was lit when the engine drove to a mission.

Featuring 3 flatbeds, the 19 meter extendable ladder was manufactured by Gugumus-Charton.
Easy to deploy by driving through narrow streets and carriage doors, the ladder allowed access to people trapped on floors and fighting fires by directing the hoses from above the hearth.

Putting together a ladder with a truck (or lorry) reconciles two assets at first hand on opposite sides. The latters consist of

using wide wheels with spokes to make the ladder work by the crew members
- insuring quick deployments from base to location.


Standard power of a PL50 was a 4-cylinder, 2.3 liter, 70HP engine
Playload was 5 tons
Hotchkiss licence manufactured Jeeps from 1952 until 1966 mostly on behalf of the French armed forces.

1962, a change of wheels for the magpies

Quick, agile, light weighted and well balanced Renault R8 started taking over from the Dauphine as the squad's workhorse in 1962. The Dauphine came up with quite a few qualities, but it was prone in capsizing with ease and this drawback could never be completed corrected.


Quintessentially Renault from the 40s until the mid 60s
the R8 was powered by a rear monted engine.
windowpanes on front doors were lowered with the conventional lever
while rear ones came up with panes going sideways by sliding.


In 1965, the deployment squad adds the souped up Gordini variant. Alongside with the standard stablemates, Gordinis were also used as part of top brass escort by clearing the motorcades' itinerary at upstream level.

Sporting the "magpie" livery, the R8 also displays a small reproduction of the coats of arms of Paris on the front doors. Coats of arms were reminders at where the vehicles were actually based

BMW Side Cars

Side-cars were among the earliest vehicles operated by the traffic squad during the late 1910s.
Coming as handy, sturdy and cheap to operate, side-cars also soldiered on location for repairs and checks of rotable parts of stranded vans, trucks and buses during the 50s. Taylored conversions were also in use for servicing and towing motorbikes.

Either Policemen or Statetroopers, locally referred as the Gendarmes, officers working astride motorbikes have been steering BMW for decades.

Selecting side-car variants of their months came as a most logical choice. As far France's Yard was concerned, they were in use by the automotive engineering department.


In 1960, enters the BMW Side-car ST, standing for Services Techniques (automotive engineering department) and coming up as a dedicated conversion for the HQ's motorcycle squads.


The most visible difference from the standard side-car was a strenghened iron-made plate
designed to transport stranded bikes back to the workshops when necessary.


The police bike squads did not operate its own servicing vehicles. The last STs were decommissioned during the late 1970s.

Part of the Paris Police HQ museum's collections, the ST on display during Heritage Days came along with a standard two-wheeler acting as the stranded bike.

TerroT "Tenace" EL

When in use from 1958 until 1961,


the air-cooled
4 strokes single cylinder
2 valve
125 cc
engined TerroT Tenace (Tenacious)
soldiered with the fire brigade
by liaiseing between field and fixed command centers
dealing with several fires at the same time.

Based at Dijon, TerroT started by manufacturing bicycles back in 1890. It lost its independance when Peugeot's Cycles branch purshased a controlling interest in May 1958.
Less than a year later, manufacturing the motor bikes moves from Dijon to Saint-Etienne.
Effective 1961, TerroT's manufacturing chapter is closed.

1955 - Introducing the once famous "Magpie" livery

Let's drive to some history on the Renault 4 CV (Chevaux/Horses)

The Renault 4CV is an automobile produced by the French manufacturer Renault from August 1947 to July 1961. An economical "people's car" inspired by the Volkswagen Beetle, it was the first French car to sell over a million units.

The 4CV was originally conceived and designed covertly by Renault engineers during the German occupation of France during World War II, when the manufacturer was under strict orders to design and produce only commercial and military vehicles. A design team led by Fernand Picard, Charles-Edmond Serre and Jean-Auguste Riolfo envisioned a small, economical car suitable for the economically difficult years which would inevitably follow the war. The first prototype was completed in 1942 and two more prototypes were produced in the following three years, with the 4CV ultimately presented to the public and media at the 1946 Paris Motor Show, though it would be another year before the cars were available for sale. In 1940 Louis Renault had spelled out to his team the need to "make him a car like the Germans"and now the new car featured a dummy grill comprising (until replaced by a simplified arrangement in 1954) six thin horizontal strips, intended to distract attention from the similarity of the car's overall architecture to that of the German Volkswagen, and to recall the modern designs of the fashionable front engined passenger cars produced in Detroit during the earlier 1940s. Importantly, despite its overall length of just 3.6 meters, the little Renault differed from the Beetle in offering four doors.

On the 4CV's launch, it was nicknamed "La motte de beurre" (the lump of butter) due to the combination of its shape and the fact that many early models were painted with sand-yellow-coloured surplus paint (also known as "European Sand") originally intended for the German Army vehicles of Rommel's Afrika-Corps The 4CV was powered by a 748 cc "Ventoux" rear engine producing 17 hp (13 kW), which was coupled to a three-speed manual transmission and featured suicide doors. Despite an initial period of uncertainty and poor sales due to the ravaged state of the French economy, the 4CV had sold 37,000 units by mid-1949 and was the most popular car in France. The car remained in production for more than a decade afterwards. Claimed power output increased subsequently to 21 hp (16 kW) as increased fuel octanes allowed for higher compression ratios, which along with the relatively low weight of the car (620 kg) enabled the manufacturers to report an 0 - 90 km/h (56 mph) time of 38 seconds and a top speed barely under 100 km/h (62 mph). The engine was notable also for its elasticity, the second and top gear both being usable for speeds between 5 km/h (3mph) and 100 km/h (62 mph): the absence of synchromesh on first gear would presumably have discouraged use of the bottom gear except when starting from rest.

The rear mounting of the engine meant that the steering could be highly geared while remaining relatively light: in the early cars only 2¼ turns were needed from lock to lock. The unusually direct steering no doubt delighted some keen drivers, but road tests of the time nonetheless included warnings to take great care with the car's handling on wet roads. In due course the manufacturers switched from one extreme to the other, and on later cars 4½ turns were needed to turn the steering wheel from lock to lock.

The 4CV's direct replacement was the Dauphine, launched in 1956, but the 4CV in fact remained in production until 1961. The 4CV was replaced by the Renault 4 which used the same engine as the 4CV and sold for a similar price.

Although most of the cars were assembled at Renault's Île Seguin plant located on an island in the river opposite Billancourt, the 4CV was also assembled in seven other countries, being Australia, Belgium, England, Ireland, Japan (where the Hino assembled examples gained a reputation for superior quality), Spain and South Africa] 1,105,543 cars were produced; the 4CV became the first French car to sell over a million.

The 4CV was easily modified and was used extensively as a racing car. The first collaboration between the Alpine company and Renault was the Alpine A-106 which was based on the 4CV. The partnership which would go on to win the World Rally Championship with the legendary Alpine A-110 in later years,

Let's keep driving with the car on display las September 19th/20th

The "Thirty Glorious Years" locally referred as Les Trente Glorieuses are elapsing and France's yard was shopping around for a suitable replacement of the Renault Juva Quatre in use since the late 30s. In 1955, an initial batch of ten cars is taken up for full scale trial. Success with regular users and public at large was instant. Representatives dispatched by various foreign police forces even come on fact-finding trips. In 1956, 20 cars are added. Before actual use, the french yard's technical dept conducted a number of alterations to correct drawbacks from the standard model.

Together with the introduction of the black and white "magpie" livery which stayed until the early 1980s, they featured a lightened custom rebuilt aluminium alloy body coming along with

a more powerful engine fitted with a compressor. Most visble alterations included a much enlarged rear window

plus new side doors and windows

Road stability was also improved by shortening the shock absorbers. However, modifications proved to be too expensive on a large fleet scale and the then new coming Renault Dauphine was finally selected. The car on display is not an original. But the restoration was conducted to render one of those custom rebuilt 4CV once on use.

Heritage Days, Police Headquarters, Part-II, Citroën Traction Avant 11 cv

Let's start

with some history to start with (source Wikipedia)

The Traction Avant, French for "forward traction", was designed by André Lefèbvre and Flaminio Bertoni in late 1933 / early 1934. While not the first production front wheel drive car - Alvis built the 1928 FWD in the UK , Cord produced the L29 from 1929 to 1932 in the United States and DKW the F1 in 1931 in Germany - it was the most successful.

Not only was the Traction Avant's drive train innovative, so was its arc-welded monocoque (unitized body). Most other cars of the era were based on a separate frame (chassis) onto which the non-structural body ("coachwork") was built. Monocoque construction (also called Unit Body or "Unibody" today) results in a lighter vehicle, and is now used for virtually all car construction, although body-on-frame construction is still suitable for larger vehicles such as trucks.

This method of construction was viewed with great suspicion in many quarters, with doubts about its strength. A type of crash test was developed, taking the form of driving the car off a cliff, to illustrate its great inherent resilience.

The novel design made the car seem very low-slung relative to its contemporaries — the Traction Avant always possessed a unique look, which went from appearing rakish in 1934 to familiar and somewhat old fashioned by 1955.

The suspension was very advanced for the car's era. The front wheels were independently sprung, using a torsion bar and wishbone suspension arrangement, where most contemporaries used live axle and cart-type leaf spring designs. The rear suspension was a simple steel beam axle and Panhard rod, trailing arms and torsion bars attached to a 3-inch (76 mm) steel tube, which in turn was bolted to the "monocoque".

Since it was considerably lighter than "conventional" designs of the era, it was capable of 100 km/h (62 mph), and consumed gasoline / petrol only at the rate of 10 litres per 100 kilometres (28 mpg-imp; 24 mpg-US).

Some summarized history

about the one on display during Heritage Days on September 19th and 20th.

The Traction Avant was quickly noticed by the Police-Headquarter which then shopped around for a sturdy, access friendly, fast and road capable car. Selecting the Citroën was not a surprise.

In 1939, the first cars were put in use. Together with strenghened torsion bars and an hydraulic braking system, the cars delivered to the HQ came along with a bulbed custom arranged grille, which concealed an advanced radio set for communication while batteries were fitted in the boot.
Last but not least, deilivered cars were powered by the 11 CV/1911 cc engine. The car on display was restored in 2008.

Main missions conducted with the Tractions were escort and security over a long period of time.

From 1945 ownwards, the Traction-Avants became a must among the pieces of equipment in use by the "Police Judiciaire" or "PJ" as most refer to the department. As the detective division of the national police, the "PJ" is the French equivalent of the Yard.
