INTRODUCTION

Launched in 1981 under prototype rules (Group 5), the Visa Trophée was to be Citroën Compétitions‘ bid in rallying competition to help promote the image of the Visa as being a tough and reliable car aimed towards the female market. In 1982, when Group B was implemented to replace Group 4, Citroën was the very first manufacturer to homologate their machine in the new category.

HISTORY (summary)

  • VISA TROPHÉE

While the fire-breathing Group B/12 supercars gathered most of the attention and are responsible for the legendary fame behind Group B, they actually are but a very small portion of the cars that got homologated over the Golden Era‘s history. In fact, some lesser Group B classes actually were of lower performance than Group A cars. It is a common oversight to forget the more humble B9-10-11 classes that provided the low-powered, cheap to buy, entry level cars with the same liberties for improvement as the B/12 “top dogs”.

The Visa Trophée was designed specifically for the entry-level rally car market such as privateers and dealership teams. Based on the production Visa GT, the cars were built by French firm Heuliez, and subsequently shipped to Citroën Competitions to be prepped as rally cars. Per the Group B engine displacement regulations, the Visa Trophée would compete in the lowest B/9 class for engines under 1300 cc. In France, the car was also heavily marketed towards women in hopes of luring them into the world of competitive rallying.

  • VISA CHRONO

By the end of 1982, Citroën updated the Visa rally car with the “Chrono” evolution (ET). It sported a larger displacement engine (1360 cc) and minor exterior changes, shifting the car into the B/10 class. Only 20 of these cars were built to satisfy evolution homologation; 12 were reserved for Citroën Competitions, the remaining 8 were offered to the most successful privateers who had run Visa Trophées in the previous year of the French Rally Championship.

  • VISA MILLE PISTES

Encouraged by their good results with the front wheel drive rally Visas, Citroën Competitions wanted to up the ante with yet another more evolved version. At the time, Citroën was very busy developing their top tier Group B contender, the BX 4TC, so they entrusted the primary development of the future Visa entry-level rally car via a design contest between various engineering firms.

Between 1981 and 1983, multiple prototype variations of the Visa were built and tested (click on the link for more details on those). Citroën set out their chosen prototypes to the 1983 Mille Pistes Rally for final review. The winner ended up being prototype #202 code-named “4×4 M”: a four wheel drive design of the firm Denis Mathiot Compétition (DMC).  200 cars were subsequently produced to officially homologate the car into Group B (B/10) on March 1st of 1984. In recompense, Mathiot would get the contract of building the twenty evolution (ET) cars.

The Visa Mille Pistes had a bit of a hard time competing in tarmac rallies since the car’s four wheel drive system didn’t include a centre differential. However, it felt much more at home on slippery surfaces and was the definitive car to beat in its class.

All Visa Group B cars were not included into the infamous 1986 Group B ban and were allowed to continue on competing up until the expiration of their respective homologation. The Mille Pistes in particular would give the finest crop of Group A cars a run for their money early on.

HOMOLOGATION VERSIONS

  • VISA TROPHÉE

Built in late 1981, the Visa Thophée was produced at 200 examples to satisfy the Group B regulations and was the very first car officially homologated into the new category (# B-200). All of the road cars were built by Carrosserie Heuliez.

Sporting a 1219 cc engine and light weight plastic panels, the Visa Trophée was a peppy car perfect for blazing away in the French countryside.

  • VISA CHRONO / II

Presented to the public in the spring of 1982, the Chrono sported a larger 1360 cc engine, upscale dashboard, lightweight wheels, riveted extended wheel arches, sportier bodywork, and special graphics. Only 20 of these cars were actually built with the new engine to satisfy the “evolution” Group B homologation requirement. However, Citroën would offer the appearance package to the public with the “Chrono II” series. A total of 3810 of these specially-trimmed cars were produced over a two year period.

  • VISA MILLE PISTES / 1000

The Mille Pistes, originally designed by Denis Mathiot Compétitions, was Citroën’s first attempt at a four wheel drive rally and homologation vehicle. As were the other rally inspired Visas it was based on the GT model but was much modified underneath the skin.

A limited production of 200 cars was made to homologate the car for Group B competition. It can be easily differentiated from the other Visa models by the “X”  in between the “Citroën chevrons” on the front grille.

The car was quite difficult to handle in tight spaces since it didn’t sport a centre differential. As such, a button was placed on the dashboard to disconnect the read axle and allow for easier parking manoeuvres. This made the Mille Pistes not quite the ideal city car but it could humble sportier cars on the dusty back roads.
