The full Traction Avant 11A history


Pre production

The car with serial number 100 000 and engine number 000890 is presented for type approval which is granted on June 6th 1934.
The first 11A, a 11 C.P.V.L. (fixed head coupe), is registered June 11th 1934. This prototype is equipped with the 7S engine which has a sump breather that differs from the later 11 engines. It also features the Pausodyne engine suspension unlike first production cars which have the old Moteur Flottant system until November 1934.


In 1934, from June onwards, 5052 11As are built. Only 3300 cars are sold and therefore in October 1934 production is temporarly ceased in order to sell the remaining stock first. The cars get their serial number when the purchase order has been confirmed and it is quite likely that the cars put into storage first, came out last.

Characteristics for the 1934 11A when launched:



  • Bumpers:
    The bumpers are the same as on all Traction Avants until 1952 with the difference that the 11A doesn't have overriders (just like other 1934 Traction Avants).

  • Horns:
    The very early 1934 11As have their horns on the front bumper as on the 7A and 7B. From October onwards the horns are fitted behind grilles in the front wings. First these are secured to the back of the horn grille with a rubber ring in between. Due to the extra strain this puts on the wings this is later replaced by fitting the horns on a bracket on the bumper supports. These horns are still located behind the grilles in the wings.

  • Grille:
    The first 11As have a grille which is very similar to those found on the 7 and 11AL with the curved top, but this is soon changed to a more flat top. These grilles have a shallow dent for the grill nose. All 1934 11As have chromed grilles made from cupper with a round crank hole. All 1934 cars have the chevrons behind the grille. On some cars the bars and grille surround are seperate pieces.

  • Front wings:
    The first cars with the horns on the bumper don't have the grilles in the wings.
    Width (measured along headlight support): 68 cm.
    Height (measured from headlight support straight down): 29,5 cm.
    In October these wings are replaced by ones with small round grilles behind which the horns are mounted. The grilles are 9 cm from the bottom of the wing and are painted the same color as the wings but chromed or enamelled grilles are an option. Width and height of the wing are still the same.

  • Headlights:
    The headlights are 220mm in diameter and have flat glass. The headlight supports are completely closed.

  • Bonnet:
    11As built before early 1936 have an extra edge along the front of the bonnet. All 1934 11As have the bonnet shutter handles on the rear of the shutters. The early cars have shutters which all open at the rear, later cars have front shutters which open at the front.

  • Windscreen surround:
    All 1934 cars have a chromed steel windscreen surround. Later cars have an aluminium windscreen surround.

  • Wheels:
    Some 1934 11As have 5 stud wheels, but most have 6 stud ones. Hubcaps for both wheels are secured without the center bolt. The 5 stud hubcap is pressed into a ring on the wheel, the 6 stud hubcap is pressed over a ring on the wheel. The 6 stud hubcaps have a rounded edge, so that it is possible to tell from the covers whether 5 or 6 stud wheels are mounted. Tyre sizes are 150x40 for the Berline and 160x40 for Familiale and Limousine.

  • Body:
    All 1934 11As have ventilated sills with a cold air feed for the right jambonneau which has the exhaust going through it. Other features are twin air inlets below the windscreen, no bootlid, flat floor without reinforcement dents and no raingutters. From July 1934 the Familiales and Limousines are available and these have a hole below the rear door which is covered by a plug. On the Cabriolet, there is no dickey seat lid handle. The dickey is opened by a lever on the hood tray.

  • Doors:
    The doors don't have the alu trim strip and the rubber knobs are mounted in the doors, while on later cars these rubbers are mounted in the body. On the long wheelbase cars, the front and rear doors look identical.

  • Rear wings:
    The wings have a very small width and are the identical to those of a 7 of the same age. Each wing has a hole with a curved edge for a rear light 29 cm above the bottom of the wing.

  • Rear lights:
    Two round rear lights are located in the rear wings. The lights have a pressed steel profiled edge and flat red glass with a small "lump" in the center.

  • Rear license plate holder:
    The illuminated license plate holder is mounted in the middle above the rear bumper, mounted on brackets secured between the body and the dress panel between the wings. The license plate is lit by painting the digit negatives on transparent plastic, with two lights behind the plastic in the holder.

  • Spare wheel cover:
    The spare wheel cover is made up by several pieces. One piece is put on the body, after which the wheel is placed on the body and secured. Then the outer piece is put on the wheel. A chromed steel ring with a spring in it keeps the 2 pieces together. The hubcap is put on last securing the cover to the wheel.


  • Floor:
    The floor is flat without reinforcement dents. The sill which carries the front seats/bench has a compartment for the jack if a front bench is fitted to the car. When separate seats have been fitted (optional) the compartment is not available (the space is used for fixation of the seats).

  • Dashboard:
    The dashboard has a central placed combined speedometer (130 km/h), oil pressure meter, fuel gauge (50 liter) and amp meter with black digits on white background and red meter hands. It also has 2 glove compartments. The lights are operated by a switch to the right of the speedometer and a ring on the steering wheel. The horns are operated by a knob in the centre of the steering wheel. The gear selector surround has arabic digits and is the same shape and size as the light switch surround. On early cars the dashboard is painted with wood imitation paint.

  • Pedals:
    11As built before November 1934 (Moteur Flottant) have the same round pedals as the 7. From November onwards side mounted square pedals (fully rubber covered and different to later types) are fitted. (Note: We know of at least 1 Moteur Flottant engined car that has these pedals.)

  • Front seat:
    Normally 11As have a front bench for 3 persons without the chrome bar at the top of the back rest. This bench is covered with plain grey cloth with two longitudinal bars stitched in it. Separate seats are optional.

  • Rear seat:
    The rear bench is upholstered the same way as the front one. Because these cars don't have a boot lid, the rear back rest can be opened, hinging at the top and secured with 2 leather straps.

  • Door panels:
    The door panels are from the same material as the benches and have a curve stitched into them, filled with wood. The doors have a small pocket for roadmaps.

  • Window surrounds:
    On early cars the window surrounds are painted with wood imitation paint.


Early 1935 the Tracta driveshafts are replaced by Rzeppa ones. The body now gets raingutters above the doors and a reinforced floor. The front bonnet shutters now have their handles at the front. On the Cabriolet the dickey seat lid now has an exterior handle.


In the beginning of 1936 the upholstery is simplified and less luxureous. A new air filter makes the engine less loud. 14 berlines without bootlid are built this year. The Familiale and Limousine now also get the bootlid (2 without bootlid are built).


In February, because of standarisation of parts, the 11A is renamed to 11B and is now largely identical the the 11BL. The detailed history of this type can be found in the Traction Avant 11B section.
